Delivery of Shareholder Documents. The Securities and Exchange Commission (the “SEC”) permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called “householding” and it helps eliminate duplicate mailings to shareholders.

Eaton Vance, or your financial adviser, may household the mailing of your documents indefinitely unless you instruct Eaton Vance, or your financial adviser, otherwise.

If you would prefer that your Eaton Vance documents not be householded, please contact Eaton Vance at 1-800-262-1122, or contact your financial adviser.

Your instructions that householding not apply to delivery of your Eaton Vance documents will be effective within 30 days of receipt by Eaton Vance or your financial adviser.

Portfolio Holdings. Each Eaton Vance Fund and its underlying Portfolio (if applicable) will file a schedule of its portfolio holdings on Form N-Q with the SEC for the first and third quarters of each fiscal year. The Form N-Q will be available on the Eaton Vance website www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR database on the SEC’s website at www.sec.gov. Form N-Q may also be reviewed and copied at the SEC’s public reference room in Washington, D.C. (call 1-800-732-0330 for information on the operation of the public reference room).

Proxy Voting. From time to time, funds are required to vote proxies related to the securities held by the funds. The Eaton Vance Funds or their underlying Portfolios (if applicable) vote proxies according to a set of policies and procedures approved by the Funds’ and Portfolios’ Boards. You may obtain a description of these policies and procedures and information on how the Funds or Portfolios voted proxies relating to portfolio securities during the most recent 12 month period ended June 30, without charge, upon request, by calling 1-800-262-1122.

Eaton Vance Insured Municipal Bond Funds as of March 31, 2009

INVESTMENT UPDATE

Eaton Vance Insured Municipal Bond Funds (the “Funds”) are closed-end funds traded on the NYSE Alternext U.S., which are designed to provide current income exempt from regular federal income tax, federal alternative minimum tax and, in state specific funds, state personal income taxes. The Funds invest primarily in high-grade municipal securities that are insured as to the timely payment of principal and interest.

Economic and Market Conditions

The six-month period ending March 31, 2009, was characterized by continued market and economic upheaval during the first two and a half months of the period, followed by the first sustained municipal bond rally of this bear market in the second half. The U.S. economy, as measured by gross domestic product (GDP), contracted sharply in both the fourth quarter of 2008 and the first quarter of 2009 by 6.2% and 6.1%, respectively, according to the U.S. Department of Commerce. The first quarter 2009 figure was a preliminary estimate. Most of the major GDP components contributed to the decline, but a sharp downturn in consumer spending was particularly influential and continued to weigh on the economy in early 2009. While high commodity prices eased since their summertime peaks, consumers continued to pare spending as they remained cautious of what increasingly became a weaker economic environment. Rising unemployment levels, at a five-year high at period end, led to constrained personal consumption and overall economic contraction. The housing market continued to weigh on the economy during the first three months of the period, with new and existing home sales falling hard in the fourth quarter of calendar 2008.

In the first quarter of 2009, the U.S. economy began showing some signs of life. Although most economists forecast anemic growth for the remainder of the year, some of the data turned more positive early on. February was a particularly strong month for economic data: factory orders increased 1.8%; new home sales rose 4.7% — the first increase in seven months; and existing home sales surged 5.1%, the largest monthly gain since 2003. The upturn in the housing market was bolstered by historically low mortgage rates, an $8,000 tax credit for first-time home buyers that was part of President Obama’s stimulus legislation; and a plethora of distressed properties on the market.

The capital markets experienced steep declines in the first two and a half months of the period, followed by a welcome rally during the latter three and a half months. The semiannual period was preceded by a number of distressing events in the fall of 2008, resulting in a freefall in both the credit and equity markets. Several calamitous events occurred in September alone, including the federal takeover of federally chartered mortgage giants Fannie Mae and Freddie Mac, the bankruptcy of Lehman Brothers and the announcement by Bank of America that it was acquiring Merrill Lynch. These actions, along with several other corporate shakeups, bank failures and bailouts, drastically redefined the Wall Street landscape.

In response, the U.S. government enacted a number of bold stimulus programs. Last fall, Congress approved a $700 billion program authorizing the federal government to purchase troubled assets from financial institutions, a program that continued to evolve since the bill was enacted into law. On February 17, 2009, President Obama signed a historic $787 billion stimulus program into law and outlined a $50 billion foreclosure rescue plan. Additionally, between September 30, 2008, and December 31, 2008, the U.S. Federal Reserve (the Fed) lowered the federal funds rate to a range of 0.0% to 0.25% from 2.00%. Also during the six-month period, the Fed took extraordinary actions through a variety of innovative lending techniques in an attempt to ease the credit crisis.

Management Discussion

Relative to the Funds’ primary benchmark, the Barclays Capital Municipal Bond Index¹ (the Index) — a broad-based, unmanaged index of municipal bonds — the Funds underperformed for the six months ending March 31, 2009. As a result of an active management style that focuses on income and longer call protection, the Funds generally hold longer-maturity bonds relative to other bond funds and the Index. Much of their underperformance occurred in the first

Fund shares are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

These views are subject to change at any time based upon market or other conditions, and the investment adviser disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a fund are based on many factors, may not be relied on as an indication of trading intent on behalf of any Eaton Vance fund.

INVESTMENT UPDATE

three months of the period and, management believes, can be attributed to the continued shift of investors’ capital into shorter-maturity bonds — a result of the broader-based credit crisis — during this period. The move to shorter-term investments was originally driven by uncertainty surrounding financial companies’ exposure to subprime mortgage-backed debt, but it later spread to the muni market when major municipal bond insurers suffered rating downgrades due to their exposure to mortgage-related structured products.

Since mid-December 2008, however, the municipal market rallied considerably, and the Funds outperformed the Index. A number of factors appeared to be at work in the market’s rebound. Municipal demand, while anemic for much of last year, returned in dramatic fashion during the first quarter of 2009. Retail muni investors — those who buy municipal bonds directly or through managed products such as mutual funds — were the predominant force behind the renewed demand. While many retail investors fled the market in 2008 as a result of market volatility and intimidating news reports, the perception of risk began to mitigate during the early stages of the new year. While institutional demand was largely absent during the first quarter — as it was for much of 2008 — retail purchases kept overall demand levels strong.

Against this backdrop, we continue to manage our municipal funds with the same relative value approach that we have traditionally employed, maintaining a long-term perspective when markets exhibit extreme short-term volatility. We believe this approach has provided excellent long-term benefits to our investors over time. Furthermore, we believe that the 138.9% yield ratio of insured municipal bonds to 30-year Treasuries as of March 31, 2009 — as compared with the long-term average of 85%-90% — indicates that there is still relative value in municipal bonds when compared with their taxable counterparts.¹

Acquisition of Insured Florida Plus Municipal Bond Fund

As of the close of business on December 15, 2008, Eaton Vance Insured Municipal Bond Fund acquired the net assets of Eaton Vance Insured Florida Plus Municipal Bond Fund pursuant to a plan of reorganization approved by the shareholders of the two Funds. The acquisition was accomplished by a tax-free exchange of common shares of Eaton Vance Insured Municipal Bond Fund for the common shares of Eaton Vance Insured Florida Plus Municipal Bond Fund outstanding on December 15, 2008. See Note 11 to the Financial Statements for more information on the reorganization.

^*		The rating distribution presented above includes the ratings of securities held by special purpose vehicles in which the Fund holds a residual interest. See Note 1H to the Fund’s financial statements. Absent such securities, the Fund’s rating distribution at 3/31/09 is as follows, and the average rating is AA-.


AAA		27.2%
AA		34.0%

• Number of Issues:		157
• Average Maturity:		26.5 years
• Average Effective Maturity:		24.7 years
• Average Call Protection:		9.9 years
• Average Dollar Price:		$97.19
• TOB Leverage^**:		46.8%


**		See Note 1H to the Fund’s financial statements. Tender option bonds (TOBs) are a form of investment leverage that create an opportunity for increased income but, at the same time, create special risks (including the likelihood of greater volatility of net asset value). TOB leverage represents the amount of Floating Rate Notes outstanding at 3/31/09 as a percentage of the Fund’s net assets plus Floating Rate Notes.

¹		Returns are historical and are calculated by determining the percentage change in share price or net asset value (as applicable) with all distributions reinvested. The Fund’s performance at market share price will differ from its results at NAV. Although share price performance generally reflects investment results over time, during shorter periods, returns at share price can also be affected by factors such as changing perceptions about the Fund, market conditions, fluctuations in supply and demand for the Fund’s shares, or changes in Fund distributions. Performance results reflect the effects of auction preferred shares (for certain periods) outstanding and/or TOB investments, which are forms of investment leverage. Use of leverage creates an opportunity for increased income but, at the same time, creates special risks (including the likelihood of greater volatility of net asset value and market price of common shares). ² The Fund’s market yield is calculated by dividing the last dividend paid per common share of the semiannual period by the share price at the end of the semiannual period and annualizing the result. ³ Taxable-equivalent figure assumes a maximum 35.00% federal income tax rate. A lower tax rate would result in a lower tax-equivalent figure. ⁴ It is not possible to invest directly in an Index. The Indices’ total returns do not reflect the expenses that would have been incurred if an investor individually purchased or sold the securities represented in the Indices. Index performance is available as of month end only. ⁵ The Lipper Averages are the average annual total returns, at net asset value, of the funds that are in the same Lipper Classification as the Fund. It is not possible to invest in a Lipper Classification. Lipper Classifications may include insured and uninsured funds, as well as leveraged and unleveraged funds. The Lipper Insured Municipal Debt Funds (Leveraged) Classification (closed-end) contained 25, 25, 25 and 20 funds for the 6-month, 1-year, 5-year and Life-of-Fund periods, respectively. Lipper Averages are available as of month end only. ⁶ Rating Distribution is determined by dividing the total market value of the issues by the total investments of the Fund. Although the investment adviser considers ratings when making investment decisions, it performs its own credit and investment analysis and does not rely primarily on the ratings assigned by the rating services. Credit quality can change from time to time, and recently issued credit ratings may not fully reflect the actual risks posed by a particular security or the issuer’s current financial condition. ⁷ Fund holdings information excludes securities held by special purpose vehicles in which the Fund holds a residual interest.

The Fund invests primarily in debt securities issued by New York municipalities. The ability of the issuers of the debt securities to meet their obligations may be affected by economic developments in a specific industry or municipality. In order to reduce the risk associated with such economic developments, at March 31, 2009, 93.0% of total investments are backed by bond insurance of various financial institutions and financial guaranty assurance agencies. The aggregate percentage insured by an individual financial institution ranged from 3.3% to 27.2% of total investments.

1 Significant Accounting Policies

Eaton Vance Insured Municipal Bond Fund (Insured Municipal Fund), Eaton Vance Insured California Municipal Bond Fund (Insured California Fund) and Eaton Vance Insured New York Municipal Bond Fund (Insured New York Fund), (each individually referred to as the Fund, and collectively, the Funds), are Massachusetts business trusts registered under the Investment Company Act of 1940, as amended (the 1940 Act), as non-diversified, closed-end management investment companies. Each Fund seeks to provide current income exempt from regular federal income tax, including alternative minimum tax, and, in state specific funds, taxes in its specified state.

The following is a summary of significant accounting policies of the Funds. The policies are in conformity with accounting principles generally accepted in the United States of America.

A Investment Valuation — Municipal bonds and taxable obligations, if any, are generally valued on the basis of valuations furnished by a pricing vendor, as derived from such vendor’s pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and asked prices, broker/dealer quotations, benchmark curves or information pertaining to the issuer. The pricing vendor may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security. Financial futures contracts and options on financial futures contracts listed on commodity exchanges are valued based on the closing price on the primary exchange on which such contracts trade. Interest rate swaps are normally valued using valuations provided by a pricing vendor. Such vendor valuations are based on the present value of fixed and projected floating rate cash flows over the term of the swap contract. Future cash flows are discounted to their present value using swap curves provided by electronic data services or by broker/dealers. Short-term obligations, maturing in sixty days or less, are valued at amortized cost, which approximates market value. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued at fair value using methods determined in good faith by or at the direction of the Trustees of a Fund in a manner that most fairly reflects the security’s value, or the amount that the Fund might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of all relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies, quotations or relevant information obtained from broker-dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s financial condition, and an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

B Investment Transactions and Related Income — Investment transactions for financial statement purposes are accounted for on a trade date basis. Realized gains and losses on investments sold are determined on the basis of identified cost. Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of discount.

C Federal Taxes — Each Fund’s policy is to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders each year substantially all of its taxable, if any, and tax-exempt net investment income, and all or substantially all of its net realized capital gains. Accordingly, no provision for federal income or excise tax is necessary. Each Fund intends to satisfy conditions which will enable it to designate distributions from the interest income generated by its investments in municipal obligations, which are exempt from regular federal income tax when received by each Fund, as exempt-interest dividends.

At September 30, 2008, the following Funds, for federal income tax purposes, had capital loss carryforwards which will reduce the respective Fund’s taxable income arising from future net realized gains on investment transactions, if any, to the extent permitted by the Internal Revenue Code, and thus will reduce the amount of distributions to shareholders which would otherwise be necessary to relieve the Funds of any liability for federal income or excise tax. The amounts and expiration dates of the capital loss carryforwards are as follows:


Fund	Amount		Expiration Date

Insured Municipal	$	1,865,536		September 30, 2016
Insured California		533,889		September 30, 2016
Insured New York		125,998		September 30, 2013

Additionally, at September 30, 2008, the Insured Municipal Fund, Insured California Fund and Insured New York Fund had net capital losses of $15,093,874, $6,143,626 and $3,724,445, respectively, attributable to security transactions incurred after October 31, 2007. These net capital losses are treated as arising on the first day of the Funds’ taxable year ending September 30, 2009.

As of March 31, 2009, the Funds had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. Each of the

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT’D

Funds’ federal tax returns filed in the 3-year period ended September 30, 2008 remains subject to examination by the Internal Revenue Service.

D Expense Reduction — State Street Bank and Trust Company (SSBT) serves as custodian of the Funds. Pursuant to the respective custodian agreements, SSBT receives a fee reduced by credits, which are determined based on the average daily cash balance each Fund maintains with SSBT. All credit balances, if any, used to reduce each Fund’s custodian fees are reported as a reduction of expenses in the Statements of Operations.

E Legal Fees — Legal fees and other related expenses incurred as part of negotiations of the terms and requirement of capital infusions, or that are expected to result in the restructuring of, or a plan of reorganization for, an investment are recorded as realized losses. Ongoing expenditures to protect or enhance an investment are treated as operating expenses.

F Use of Estimates — The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates.

G Indemnifications — Under each Fund’s organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to each Fund, and shareholders are indemnified against personal liability for the obligations of each Fund. Additionally, in the normal course of business, each Fund enters into agreements with service providers that may contain indemnification clauses. Each Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against each Fund that have not yet occurred.

H Floating Rate Notes Issued in Conjunction with Securities Held — The Funds may invest in inverse floating rate securities, also referred to as tender option bonds (TOBs), whereby a Fund may sell a fixed rate bond to a broker for cash. At the same time, the Fund buys a residual interest in the assets and cash flows of a Special-Purpose Vehicle (the SPV), (which is generally organized as a trust), set up by the broker, often referred to as an inverse floating rate obligation (Inverse Floater). The broker deposits a fixed rate bond into the SPV with the same CUSIP number as the fixed rate bond sold to the broker by the Fund, and which may have been, but is not required to be, the fixed rate bond purchased from the Fund (the Fixed Rate Bond). The SPV also issues floating rate notes (Floating Rate Notes) which are sold to third-parties. The Inverse Floater held by a Fund gives the Fund the right (1) to cause the holders of the Floating Rate Notes to tender their notes at par, and (2) to have the broker transfer the Fixed Rate Bond held by the SPV to the Fund, thereby terminating the SPV. Should the Fund exercise such right, it would pay the broker the par amount due on the Floating Rate Notes and exchange the Inverse Floater for the underlying Fixed Rate Bond. Pursuant to Financial Accounting Standards Board (FASB) Statement No. 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities” (FAS 140), the Funds account for the transaction described above as a secured borrowing by including the Fixed Rate Bond in their Portfolio of Investments and the Floating Rate Notes outstanding as a liability under the caption “Payable for floating rate notes issued” in their Statement of Assets and Liabilities. The Floating Rate Notes have interest rates that generally reset weekly and their holders have the option to tender their notes to the broker for redemption at par at each reset date. Interest expense related to the Funds’ liability with respect to Floating Rate Notes is recorded as incurred. The SPV may be terminated by the Fund, as noted above, or by the broker upon the occurrence of certain termination events as defined in the trust agreement, such as a downgrade in the credit quality of the underlying bond, bankruptcy of or payment failure by the issuer of the underlying bond, the inability to remarket Floating Rate Notes that have been tendered due to insufficient buyers in the market, or the failure by the SPV to obtain renewal of the liquidity agreement under which liquidity support is provided for the Floating Rate Notes up to one year. Structuring fees paid to the liquidity provider upon the creation of an SPV have been recorded as debt issuance costs and are being amortized as interest expense to the expected maturity date of the related trust. At March 31, 2009, the amounts of the Funds’ Floating Rate Notes and related interest rates and collateral were as follows:

139,875,000

0.68 – 1.75

140,182,909

The Funds may enter into shortfall and forbearance agreements with the broker by which a Fund agrees to reimburse the broker, in certain circumstances, for the difference between the liquidation value of the Fixed Rate Bond held by the SPV and the liquidation value of the Floating Rate Notes, as well as any shortfalls in interest cash flows. The Funds’ exposure under shortfall and forbearance agreements that were entered into as of March 31, 2009 was approximately $17,606,000,

Eaton Vance Insured Municipal Bond Funds as of March 31, 2009

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT’D

$5,770,000 and $1,169,000 for the Insured Municipal Fund, Insured California Fund and Insured New York Fund, respectively.

The Funds may also purchase Inverse Floaters from brokers in a secondary market transaction without first owning the underlying fixed rate bond. Such transactions are not required to be treated as secured borrowings. Shortfall agreements, if any, related to Inverse Floaters purchased in a secondary market transaction are disclosed in the Portfolio of Investments. The Funds’ investment policies and restrictions expressly permit investments in Inverse Floaters. Inverse floating rate securities typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality and maturity. These securities tend to underperform the market for fixed rate bonds in a rising long-term interest rate environment, but tend to outperform the market for fixed rate bonds when long-term interest rates decline. The value and income of inverse floating rate securities are generally more volatile than that of a fixed rate bond. The Funds’ investment policies do not allow the Funds to borrow money for purposes of making investments. Management believes that the Funds’ restrictions on borrowing money and issuing senior securities (other than as specifically permitted) do not apply to Floating Rate Notes issued by the SPV and included as a liability in the Funds’ Statements of Assets and Liabilities. As secured indebtedness issued by an SPV, Floating Rate Notes are distinct from the borrowings and senior securities to which the Funds’ restrictions apply. Inverse Floaters held by the Funds are securities exempt from registration under Rule 144A of the Securities Act of 1933.

I Financial Futures Contracts — The Funds may enter into financial futures contracts. The Funds’ investment in financial futures contracts is designed for hedging against changes in interest rates or as a substitute for the purchase of securities. Upon entering into a financial futures contract, a Fund is required to deposit with the broker, either in cash or securities an amount equal to a certain percentage of the purchase price (initial margin). Subsequent payments, known as variation margin, are made or received by the Fund each business day, depending on the daily fluctuations in the value of the underlying security, and are recorded as unrealized gains or losses by the Fund. Gains (losses) are realized upon the expiration or closing of the financial futures contracts. Should market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. In entering such contracts, the Fund bears the risk if the counterparties do not perform under the contracts’ terms.

J Interest Rate Swaps — A Fund may enter into interest rate swap agreements to enhance return, to hedge against fluctuations in securities prices or interest rates, or as substitution for the purchase or sale of securities. Pursuant to these agreements, a Fund makes periodic payments at a fixed interest rate and, in exchange, receives payments based on the interest rate of a benchmark industry index. During the term of the outstanding swap agreement, changes in the underlying value of the swap are recorded as unrealized gains or losses. The value of the swap is determined by changes in the relationship between two rates of interest. A Fund is exposed to credit loss in the event of non-performance by the swap counterparty. Risk may also arise from movements in interest rates.

K When-Issued Securities and Delayed Delivery Transactions — The Funds may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. At the time the transaction is negotiated, the price of the security that will be delivered is fixed. The Funds maintain security positions for these commitments such that sufficient liquid assets will be available to make payments upon settlement. Securities purchased on a delayed delivery or when-issued basis are marked-to-market daily and begin earning interest on settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

L Statement of Cash Flows — The cash amount shown in the Statement of Cash Flows of a Fund is the amount included in the Fund’s Statement of Assets and Liabilities and represents the cash on hand at its custodian and does not include any short-term investments.

M Interim Financial Statements — The interim financial statements relating to March 31, 2009 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Funds’ management, reflect all adjustments, consisting of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2 Distributions to Shareholders

Each Fund intends to make monthly distributions of net investment income to common shareholders. In addition, at least annually, each Fund intends to distribute all or substantially all of its net realized capital gains, (reduced by available capital loss carryforwards from prior years, if any). Distributions are recorded on the ex-dividend date.

The Funds distinguish between distributions on a tax basis and a financial reporting basis. Accounting principles generally accepted in the United States of America require that only distributions in excess of tax basis earnings and profits be reported in the financial statements as a return

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT’D

of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid-in capital.

3 Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Eaton Vance Management (EVM) as compensation for investment advisory services rendered to each Fund. The fee is computed at an annual rate of 0.65% of each Fund’s average weekly gross assets and is payable monthly. Average weekly gross assets include the principal amount of any indebtedness for money borrowed, including debt securities issued by a Fund. Pursuant to a fee reduction agreement with EVM, average weekly gross assets are calculated by adding to net assets the amount payable by the Fund to floating rate note holders, such adjustment being limited to the value of the Auction Preferred Shares (APS) outstanding prior to any APS redemptions by the Fund. EVM also serves as the administrator of each Fund, but receives no compensation.

In addition, EVM has contractually agreed to reimburse the Funds for fees and other expenses at an annual rate of 0.32% of average weekly gross assets of each Fund during the first five full years of its operations, 0.24% of a Fund’s average weekly gross assets in year six, 0.16% in year seven and 0.08% in year eight. The Funds concluded their first six full years of operations on August 30, 2008. For the six months ended March 31, 2009, the investment adviser fee and expenses contractually reduced by EVM were as follows:


			Expenses
	Investment		Reduced by
Fund	Adviser Fee		EVM

Insured Municipal	$	4,047,278	$	1,023,204
Insured California		1,358,972		334,491
Insured New York		985,327		246,682

Except for Trustees of the Funds who are not members of EVM’s organization, officers and Trustees receive remuneration for their services to the Funds out of the investment adviser fee. Trustees of the Funds who are not affiliated with the investment adviser may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the six months ended March 31, 2009, no significant amounts have been deferred. Certain officers and Trustees of the Funds are officers of EVM.

4 Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations, for the six months ended March 31, 2009 were as follows:

7 Overdraft Advances

Pursuant to the respective custodian agreements, SSBT may, in its discretion, advance funds to the Funds to make properly authorized payments. When such payments result in an overdraft, the Funds are obliged to repay SSBT at the current rate of interest charged by SSBT for secured loans (currently, a rate above the Federal Funds rate). This obligation is payable on demand to SSBT. SSBT has a lien on a Fund’s assets to the extent of any overdraft. At March 31, 2009, the Insured Municipal Fund and Insured California Fund had payments due to SSBT pursuant to the foregoing arrangement of $2,063,106 and $786,560, respectively.

8 Financial Instruments

The Funds may trade in financial instruments with off-balance sheet risk in the normal course of their investing activities. These financial instruments may include financial futures contracts and interest rate swaps and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial statement purposes. The notional or contractual amounts of these instruments represent the investment a Fund has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered.

A summary of obligations under these financial instruments at March 31, 2009 is as follows:

9 Fair Value Measurements

The Funds adopted FASB Statement of Financial Accounting Standards No. 157 (FAS 157), “Fair Value Measurements”, effective October 1, 2008. FAS 157 established a three-tier hierarchy to prioritize the assumptions, referred to as inputs, used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.


	•	Level 1 – quoted prices in active markets for identical investments

Eaton Vance Insured Municipal Bond Funds as of March 31, 2009

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT’D


	•	Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

	•	Level 3 – significant unobservable inputs (including a fund’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

At March 31, 2009, the inputs used in valuing the Funds’ investments, which are carried at value, were as follows:


Insured Municipal Fund

		Investments in		Other Financial
	Valuation Inputs	Securities		Instruments*

Level 1	Quoted Prices	$	—	$	—
Level 2	Other Significant Observable Inputs		1,309,211,069		(6,726,452	)

Level 3	Significant Unobservable Inputs		—		—


Total		$	313,503,477	$	(328,060	)


*		Other financial instruments are futures and swap contracts not reflected in the Portfolio of Investments, which are valued at the unrealized appreciation (depreciation) on the instrument.

The Funds held no investments or other financial instruments as of September 30, 2008 whose fair value was determined using Level 3 inputs.

10 Recently Issued Accounting Pronouncement

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161 (FAS 161), “Disclosures about Derivative Instruments and Hedging Activities”. FAS 161 requires enhanced disclosures about an entity’s derivative and hedging activities, including qualitative disclosures about the objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk related contingent features in derivative instruments. FAS 161 is effective for fiscal years and interim periods beginning after November 15, 2008. Management is currently evaluating the impact the adoption of FAS 161 will have on the Funds’ financial statement disclosures.

11 Reorganization

As of the close of business on December 15, 2008, the Insured Municipal Fund acquired the net assets of Eaton Vance Insured Florida Plus Municipal Bond Fund (Insured Florida Plus Fund) pursuant to a plan of reorganization approved by the shareholders of the Insured Municipal Fund and Insured Florida Plus Fund. The acquisition was accomplished by a tax-free exchange of 2,748,089 common shares of the Insured Municipal Fund for the 2,575,502 common shares of Insured Florida Plus Fund outstanding on December 15, 2008. The aggregate net assets of the Insured Municipal Fund immediately before the acquisition were $487,655,526. The net assets of Insured Florida Plus Fund at that date of $20,638,318, including $10,469,624 of unrealized depreciation, were combined with those of the Insured Municipal Fund, resulting in combined net assets of $508,293,844.

DIVIDEND REINVESTMENT PLAN

Each Fund offers a dividend reinvestment plan (the Plan) pursuant to which shareholders may elect to have dividends and capital gains distributions automatically reinvested in common shares (the Shares) of the same Fund. You may elect to participate in the Plan by completing the Dividend Reinvestment Plan Application Form. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you by American Stock Transfer & Trust Company as dividend paying agent. On the distribution payment date, if the net asset value per Share is equal to or less than the market price per Share plus estimated brokerage commissions, then new Shares will be issued. The number of Shares shall be determined by the greater of the net asset value per Share or 95% of the market price. Otherwise, Shares generally will be purchased on the open market by the Plan Agent. Distributions subject to income tax (if any) are taxable whether or not shares are reinvested.

If your shares are in the name of a brokerage firm, bank, or other nominee, you can ask the firm or nominee to participate in the Plan on your behalf. If the nominee does not offer the Plan, you will need to request that your shares be re-registered in your name with each Fund’s transfer agent, American Stock Transfer & Trust Company, or you will not be able to participate.

The Plan Agent’s service fee for handling distributions will be paid by each Fund. Each participant will be charged their pro rata share of brokerage commissions on all open-market purchases.

Plan participants may withdraw from the Plan at any time by writing to the Plan Agent at the address noted on the following page. If you withdraw, you will receive shares in your name for all Shares credited to your account under the Plan. If a participant elects by written notice to the Plan Agent to have the Plan Agent sell part or all of his or her Shares and remit the proceeds, the Plan Agent is authorized to deduct a $5.00 fee plus brokerage commissions from the proceeds.

If you wish to participate in the Plan and your shares are held in your own name, you may complete the form on the following page and deliver it to the Plan Agent.

Any inquiries regarding the Plan can be directed to the Plan Agent, American Stock Transfer & Trust Company, at 1-866-439-6787.

BOARD OF TRUSTEES’ ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENTS

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended (the “1940 Act”), provides, in substance, that each investment advisory agreement between a fund and its investment adviser will continue in effect from year to year only if its continuance is approved at least annually by the fund’s board of trustees, including by a vote of a majority of the trustees who are not “interested persons” of the fund (“Independent Trustees”), cast in person at a meeting called for the purpose of considering such approval.

At a meeting of the Boards of Trustees (each a “Board”) of the Eaton Vance group of mutual funds (the “Eaton Vance Funds”) held on April 21, 2008, the Board, including a majority of the Independent Trustees, voted to approve continuation of existing advisory and sub-advisory agreements for the Eaton Vance Funds for an additional one-year period. In voting its approval, the Board relied upon the affirmative recommendation of the Contract Review Committee of the Board (formerly the Special Committee), which is a committee comprised exclusively of Independent Trustees. Prior to making its recommendation, the Contract Review Committee reviewed information furnished for a series of meetings of the Contract Review Committee held in February, March and April 2008. Such information included, among other things, the following:

Information about Fees, Performance and Expenses


	•	An independent report comparing the advisory and related fees paid by each fund with fees paid by comparable funds;
	•	An independent report comparing each fund’s total expense ratio and its components to comparable funds;
	•	An independent report comparing the investment performance of each fund to the investment performance of comparable funds over various time periods;
	•	Data regarding investment performance in comparison to relevant peer groups of funds and appropriate indices;
	•	Comparative information concerning fees charged by each adviser for managing other mutual funds and institutional accounts using investment strategies and techniques similar to those used in managing the fund;
	•	Profitability analyses for each adviser with respect to each fund;

Information about Portfolio Management


	•	Descriptions of the investment management services provided to each fund, including the investment strategies and processes employed, and any changes in portfolio management processes and personnel;
	•	Information concerning the allocation of brokerage and the benefits received by each adviser as a result of brokerage allocation, including information concerning the acquisition of research through “soft dollar” benefits received in connection with the funds’ brokerage, and the implementation of a soft dollar reimbursement program established with respect to the funds;
	•	Data relating to portfolio turnover rates of each fund;
	•	The procedures and processes used to determine the fair value of fund assets and actions taken to monitor and test the effectiveness of such procedures and processes;

Information about each Adviser


	•	Reports detailing the financial results and condition of each adviser;
	•	Descriptions of the qualifications, education and experience of the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and information relating to their compensation and responsibilities with respect to managing other mutual funds and investment accounts;
	•	Copies of the Codes of Ethics of each adviser and its affiliates, together with information relating to compliance with and the administration of such codes;
	•	Copies of or descriptions of each adviser’s proxy voting policies and procedures;
	•	Information concerning the resources devoted to compliance efforts undertaken by each adviser and its affiliates on behalf of the funds (including descriptions of various compliance programs) and their record of compliance with investment policies and restrictions, including policies with respect to market-timing, late trading and selective portfolio disclosure, and with policies on personal securities transactions;
	•	Descriptions of the business continuity and disaster recovery plans of each adviser and its affiliates;

Other Relevant Information


	•	Information concerning the nature, cost and character of the administrative and other non-investment management services provided by Eaton Vance Management and its affiliates;

Eaton Vance Insured Municipal Bond Funds

BOARD OF TRUSTEES’ ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENTS CONT’D


	•	Information concerning management of the relationship with the custodian, subcustodians and fund accountants by each adviser or the funds’ administrator; and
	•	The terms of each advisory agreement.

In addition to the information identified above, the Contract Review Committee considered information provided from time to time by each adviser throughout the year at meetings of the Board and its committees. Over the course of the twelve-month period ended April 30, 2008, the Board met eleven times and the Contract Review Committee, the Audit Committee and the Governance Committee, each of which is a Committee comprised solely of Independent Trustees, met twelve, seven and five times, respectively. At such meetings, the Trustees received, among other things, presentations by the portfolio managers and other investment professionals of each adviser relating to the investment performance of each fund and the investment strategies used in pursuing the fund’s investment objective. The Portfolio Management Committee and the Compliance Reports and Regulatory Matters Committee are newly established and did not meet during the twelve-month period ended April 30, 2008.

For funds that invest through one or more underlying portfolios, the Board considered similar information about the portfolio(s) when considering the approval of advisory agreements. In addition, in cases where the fund’s investment adviser has engaged a sub-adviser, the Board considered similar information about the sub-adviser when considering the approval of any sub-advisory agreement.

The Contract Review Committee was assisted throughout the contract review process by Goodwin Procter LLP, legal counsel for the Independent Trustees. The members of the Contract Review Committee relied upon the advice of such counsel and their own business judgment in determining the material factors to be considered in evaluating each advisory and sub-advisory agreement and the weight to be given to each such factor. The conclusions reached with respect to each advisory and sub-advisory agreement were based on a comprehensive evaluation of all the information provided and not any single factor. Moreover, each member of the Contract Review Committee may have placed varying emphasis on particular factors in reaching conclusions with respect to each advisory and sub-advisory agreement.

Results of the Process

Based on its consideration of the foregoing, and such other information as it deemed relevant, including the factors and conclusions described below, the Contract Review Committee concluded that the continuance of the investment advisory agreements of the following funds:


	•	Eaton Vance Insured Municipal Bond Fund
	•	Eaton Vance Insured California Municipal Bond Fund
	•	Eaton Vance Insured New York Municipal Bond Fund

(the “Funds”), each with Eaton Vance Management (the “Adviser”), including their fee structures, is in the interests of shareholders and, therefore, the Contract Review Committee recommended to the Board approval of each agreement. The Board accepted the recommendation of the Contract Review Committee as well as the factors considered and conclusions reached by the Contract Review Committee with respect to each agreement. Accordingly, the Board, including a majority of the Independent Trustees, voted to approve continuation of the investment advisory agreement for each Fund.

Nature, Extent and Quality of Services

In considering whether to approve the investment advisory agreements of the Funds, the Board evaluated the nature, extent and quality of services provided to the Funds by the Adviser.

The Board considered the Adviser’s management capabilities and investment process with respect to the types of investments held by each Fund, including the education, experience and number of its investment professionals and other personnel who provide portfolio management, investment research, and similar services to the Funds. In particular, the Board evaluated, where relevant, the abilities and experience of such investment personnel in analyzing factors such as credit risk, tax efficiency, and special considerations relevant to investing in municipal bonds. Specifically, the Board considered the Adviser’s large municipal bond team, which includes portfolio managers and credit specialists who provide services to the Funds. The Board also took into account the resources dedicated to portfolio management and other services, including the compensation paid to recruit and retain investment personnel, and the time and attention devoted to each Fund by senior management.

The Board also reviewed the compliance programs of the Adviser and relevant affiliates thereof. Among other matters, the Board considered compliance and reporting matters relating to personal trading by investment personnel, selective disclosure of portfolio holdings, late trading, frequent trading, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also evaluated the responses of the Adviser and its affiliates to requests from regulatory authorities such as the Securities and Exchange Commission.

Eaton Vance Insured Municipal Bond Funds

BOARD OF TRUSTEES’ ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENTS CONT’D

The Board also considered shareholder and other administrative services provided or managed by Eaton Vance Management and its affiliates, including transfer agency and accounting services. The Board evaluated the benefits to shareholders of investing in a fund that is a part of a large family of funds.

After consideration of the foregoing factors, among others, the Board concluded that the nature, extent and quality of services provided by the Adviser, taken as a whole, are appropriate and consistent with the terms of the respective investment advisory agreement.

Fund Performance

The Board compared each Fund’s investment performance to a relevant universe of similarly managed funds identified by an independent data provider and appropriate benchmark indices. The Board reviewed comparative performance data for the one-, three- and five-year periods ended September 30, 2007 for each Fund. On the basis of the foregoing and other relevant information, the Board concluded that the performance of each Fund was satisfactory.

Management Fees and Expenses

The Board reviewed contractual investment advisory fee rates, including any administrative fee rates, payable by each Fund (referred to collectively as “management fees”). As part of its review, the Board considered each Fund’s management fee and total expense ratio for the year ended September 30, 2007, as compared to a group of similarly managed funds selected by an independent data provider. The Board considered the fact that the Adviser had waived fees and/or paid expenses for each of the Funds.

After reviewing the foregoing information, and in light of the nature, extent and quality of the services provided by the Adviser, the Board concluded with respect to each Fund that the management fees charged to the Fund for advisory and related services and the total expense ratio of the Fund are reasonable.

Profitability

The Board reviewed the level of profits realized by the Adviser and, if applicable, its affiliates in providing investment advisory and administrative services to each Fund and to all Eaton Vance Funds as a group. The Board considered the level of profits realized with and without regard to revenue sharing or other payments by the Adviser and its affiliates to third parties in respect of distribution services. The Board also considered other direct or indirect benefits received by the Adviser and its affiliates in connection with their relationship with the Funds.

The Board concluded that, in light of the foregoing factors and the nature, extent and quality of the services rendered, the profits realized by the Adviser and its affiliates are reasonable.

Economies of Scale

In reviewing management fees and profitability, the Board also considered the extent to which the Adviser and its affiliates, on the one hand, and each Fund, on the other hand, can expect to realize benefits from economies of scale as the assets of the Fund increase. The Board acknowledged the difficulty in accurately measuring the benefits resulting from the economies of scale with respect to the management of any specific fund or group of funds. The Board also considered the fact that none of the Funds is continuously offered and concluded that, in light of the level of the adviser’s profits with respect to each Fund, the implementation of breakpoints in the advisory fee schedule is not appropriate at this time. Based upon the foregoing, the Board concluded that the benefits from economies of scale are currently being shared equitably by the Adviser and its affiliates and each Fund.

The Board of Trustees of the Trust has adopted a proxy voting policy and procedure (the “Fund Policy”), pursuant to which the Trustees have delegated proxy voting responsibility to the Fund’s investment adviser and adopted the investment adviser’s proxy voting policies and procedures (the “Policies”) which are described below. The Trustees will review the Fund’s proxy voting records from time to time and will annually consider approving the Policies for the upcoming year. In the event that a conflict of interest arises between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund, the investment adviser will generally refrain from voting the proxies related to the companies giving rise to such conflict until it consults with the Board’s Special Committee except as contemplated under the Fund Policy. The Board’s Special Committee will instruct the investment adviser on the appropriate course of action.

The Policies are designed to promote accountability of a company’s management to its shareholders and to align the interests of management with those shareholders. An independent proxy voting service (“Agent”), currently Institutional Shareholder Services, Inc., has been retained to assist in the voting of proxies through the provision of vote analysis, implementation and recordkeeping and disclosure services. The investment adviser will generally vote proxies through the Agent. The Agent is required to vote all proxies and/or refer then back to the investment adviser pursuant to the Policies. It is generally the policy of the investment adviser to vote in accordance with the recommendation of the Agent. The Agent shall refer to the investment adviser proxies relating to mergers and restructurings, and the disposition of assets, termination, liquidation and mergers contained in mutual fund proxies.

The investment adviser will normally vote against anti-takeover measures and other proposals designed to limit the ability of shareholders to act on possible transactions, except in the case of closed-end management investment companies. The investment adviser generally supports management on social and environmental proposals. The investment adviser may abstain from voting from time to time where it determines that the costs associated with voting a proxy outweighs the benefits derived from exercising the right to vote or the economic effect on shareholders interests or the value of the portfolio holding is indeterminable or insignificant.

In addition, the investment adviser will monitor situations that may result in a conflict of interest between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund by maintaining a list of significant existing and prospective corporate clients. The investment adviser’s personnel responsible for reviewing and voting proxies on behalf of the Fund will report any proxy received or expected to be received from a company included on that list to the personal of the investment adviser identified in the Policies. If such personnel expects to instruct the Agent to vote such proxies in a manner inconsistent with the guidelines of the Policies or the recommendation of the Agent, the personnel will consult with members of senior management of the investment adviser to determine if a material conflict of interests exists. If it is determined that a material conflict does exist, the investment adviser will seek instruction on how to vote from the Special Committee.

Information on how the Fund voted proxies relating to portfolio securities during the most recent 12 month period ended June 30 is available (1) without charge, upon request, by calling 1-800-262-1122, and (2) on the Securities and Exchange Commission’s website at http://www.sec.gov.
