MuniYield
Michigan Insured
Fund II, Inc.


www.mlim.ml.com




MuniYield Michigan Insured Fund II, Inc. seeks to provide
shareholders with as high a level of current income exempt from
Federal and Michigan income taxes as is consistent with its
investment policies and prudent investment management by investing
primarily in a portfolio of long-term municipal obligations the
interest on which, in the opinion of bond counsel to the issuer, is
exempt from Federal and Michigan income taxes.

This report, including the financial information herein, is
transmitted to shareholders of MuniYield Michigan Insured
Fund II, Inc. for their information. It is not a prospectus. Past
performance results shown in this report should not be considered a
representation of future performance. The Fund has leveraged its
Common Stock and intends to remain leveraged by issuing Preferred
Stock to provide the Common Stock shareholders with a potentially
higher rate of return. Leverage creates risks for Common Stock
shareholders, including the likelihood of greater volatility of net
asset value and market price of shares of the Common Stock, and the
risk that fluctuations in the short-term dividend rates of the
Preferred Stock may affect the yield to Common Stock shareholders.
Statements and other information herein are as dated and are subject
to change.

The Benefits
And Risks of
Leveraging


MuniYield Michigan Insured Fund II, Inc. utilizes leveraging to seek
to enhance the yield and net asset value of its Common Stock.
However, these objectives cannot be achieved in all interest rate
environments. To leverage, the Fund issues Preferred Stock, which
pays dividends at prevailing short-term interest rates, and invests
the proceeds in long-term municipal bonds. The interest earned on
these investments is paid to Common Stock shareholders in the form
of dividends, and the value of these portfolio holdings is reflected
in the per share net asset value of the Fund's Common Stock.
However, in order to benefit Common Stock shareholders, the yield
curve must be positively sloped; that is, short-term interest rates
must be lower than long-term interest rates. At the same time, a
period of generally declining interest rates will benefit Common
Stock shareholders. If either of these conditions change, then the
risks of leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock
capitalization of $100 million and the issuance of Preferred
Stock for an additional $50 million, creating a total value of
$150 million available for investment in long-term municipal bonds.
If prevailing short-term interest rates are approximately 3% and
long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million
of Preferred Stock based on the lower short-term interest rates. At
the same time, the fund's total portfolio of $150 million earns the
income based on long-term interest rates. Of course, increases in
short-term interest rates would reduce (and even eliminate) the
dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term
investments, and therefore the Common Stock shareholders are the
beneficiaries of the incremental yield. However, if short-term
interest rates rise, narrowing the differential between short-term
and long-term interest rates, the incremental yield pickup on the
Common Stock will be reduced or eliminated completely. At the same
time, the market value of the fund's Common Stock (that is, its
price as listed on the New York Stock Exchange) may, as a result,
decline. Furthermore, if long-term interest rates rise, the Common
Stock's net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Stock does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain
securities whose potential income return is inversely related to
changes in a floating interest rate ("inverse floaters"). In
general, income on inverse floaters will decrease when short-term
interest rates increase and increase when short-term interest rates
decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of
reduced or eliminated interest payments and losses of invested
principal. In addition, inverse floaters have the effect of
providing investment leverage and, as a result, the market value of
such securities will generally be more volatile than that of fixed-
rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the
net asset value of the Fund's shares may also be more volatile than
if the Fund did not invest in these securities.



Swap
Agreements


The Fund may also invest in swap agreements, which are over-the-
counter contracts in which one party agrees to make periodic
payments based on the change in market value of a specified bond,
basket of bonds or index in return for periodic payments based on a
fixed or variable interest rate or the change in market value of a
different bond, basket of bonds or index. Swap agreements may be
used to obtain exposure to a bond or market without owning or taking
physical custody of securities.

DEAR SHAREHOLDER


For the six months ended April 30, 2003, the Common Stock of
MuniYield Michigan Insured Fund II, Inc. had a net annualized yield
of 5.85%, based on a period-end per share net asset value of $15.42
and $.447 per share income dividends. Over the same period, the
total investment return on the Fund's Common Stock was +6.85%, based
on a change in per share net asset value from $14.91 to $15.42, and
assuming reinvestment of $.447 per share ordinary income dividends.

For the six-month period ended April 30, 2003, the Fund's Auction
Market Preferred Stock had an average yield of 1.09% for Series A
and 1.10% for Series B.

For a description of the Fund's total investment return based on a
change in the per share market value (as measured by the trading
price of the Fund's shares on the New York Stock Exchange), and
assuming reinvestment of dividends, please refer to the Financial
Highlights section of the Financial Statements included in this
report. As a closed-end fund, the Fund's shares may trade in the
secondary market at a premium or discount to the Fund's net asset
value. As a result, total investment returns based on changes in the
Fund's market value can vary significantly from total investment
return based on changes in the Fund's net asset value.


The Municipal Market Environment
During the six-month period ended April 30, 2003, amid considerable
weekly and monthly volatility, long-term fixed income interest rates
generally declined. Geopolitical tensions and volatile equity
valuations continued to overshadow economic fundamentals as they
have for most of the last 12 months. Reacting to the strong U.S.
equity rally that began last October, fixed income bond yields
remained under pressure in November 2002, as U.S. equity markets
continued to strengthen. During November, the Standard & Poor's 500
(S&P 500) Index rose an additional 5.50%. Equity prices were
supported by further signs of U.S. economic recovery, especially
improving labor market activity. In late November, third-quarter
2002 U.S. gross domestic product growth was 4%, well above the
second-quarter 2002 rate of 1.30%. Financial conditions were also
strengthened by a larger-than-expected reduction in short-term
interest rates by the Federal Reserve Board in early November. The
Federal Funds target rate was lowered 50 basis points (0.50%) to
1.25%, its lowest level since the 1960s. This action by the Federal
Reserve Board was largely viewed as being taken to bolster the
sputtering U.S. economic recovery. Rebounding U.S. equity markets
and the prospects for a more substantial U.S. economic recovery
pushed long-term U.S. Treasury yield levels to 5.10% by late
November.

However, into early 2003, softer equity prices and renewed investor
concerns about U.S. military action against Iraq and North Korea
again pushed bond prices higher. Reacting to disappointing holiday
sales and corporate managements' attempts to scale back analysts'
expectation of future earnings, the S&P 500 Index declined more than
10% from December 2002 to February 2003. Fearing an eventual
U.S./Iraq military confrontation in 2003, investors again sought the
safety of U.S. Treasury obligations and the prices of fixed income
issues rose. By the end of February 2003, U.S. Treasury bond yields
had declined approximately 40 basis points to 4.67%.

Bond yields continued to fall into early March. Once direct U.S.
military action against Iraq began, bond yields quickly rose. Prior
uncertainty surrounding the Iraqi situation was obviously removed
and early U.S. military successes fostered the hope that the
conflict would be quickly and positively concluded. Concurrently,
the S&P 400 Index rose over 6% as investors, in part, sold fixed
income issues to purchase equities in anticipation of a strong
U.S. economic recovery once the Iraqi conflict was resolved. By
mid-March, U.S. Treasury bond yields again rose to above 5%.
However, as there was growing sentiment that hostilities may not be
resolved in a matter of weeks, U.S. Treasury bond yields again
declined to end the month at 4.81%.

For the six months ended April 30, 2003, long-term U.S. Treasury
bond yields ratcheted back to near 5% by mid-April, as U.S. equity
markets continued to improve and the safe-haven premium U.S.
Treasury issues had commanded prior to the beginning of the Iraqi
conflict continued to be withdrawn. However, with the quick positive
resolution of the Iraqi war, investors quickly resumed their focus
on the fragile U.S. economic recovery. Business activity in the
United States has remained sluggish, especially job creation.
Investors have also been concerned that the recent SARS outbreak
would have a material, negative impact on world economic conditions,
especially in China and Japan. First quarter 2003 U.S. gross
domestic product was released in late April initially estimating
U.S. economic activity to be growing at 1.60%, well below many
analysts' assessments. These factors, as well as the possibility
that the Federal Reserve Board could again lower short-term interest
rates to encourage more robust U.S. economic growth, pushed bond
prices higher during the last two weeks of the period. By April 30,
2003, long-term U.S. Treasury bond yields had declined to almost
4.75%. Over the past six months, long-term U.S. bond yields fell
more than 20 basis points.

For the six months ended April 30, 2003, long-term tax-exempt bond
yields also fell modestly. Yield volatility was reduced relative to
that seen in U.S. Treasury issues, as municipal bond prices were
much less sensitive to worldwide geopolitical pressures on a daily
and weekly basis. Tax-exempt bond yields generally followed their
taxable counterparts higher, responding to a more positive U.S.
fixed income environment and continued slow economic growth. After
rising approximately 10 basis points in November 2002 to 5.30%,
municipal bond yields generally declined through February 2003. At
February 28, 2003, long-term tax-exempt revenue bond yields, as
measured by the Bond Buyer Revenue Bond Index, fell to approximately
5.05%. However, similar to U.S. Treasury bond yields, once military
action began in Iraq, municipal bond yields rose sharply to nearly
5.20% before declining to approximately 5.10% by the end of April.
Over the past six months, long-term tax-exempt bond yields fell
approximately 11 basis points, slightly less than U.S. Treasury
obligations.

A number of factors have combined to generate consistently strong
demand for municipal bonds throughout the six-month period ended
April 30, 2003. Generally weak U.S. equity markets have supported
continued positive demand for tax-exempt products as investors have
sought the relative security of fixed income issues. Also, with tax-
exempt money market rates near 1%, the demand for longer maturity
municipal issues has increased as investors have opted to buy longer
maturity issues rather than remain in cash reserves. Additionally,
investors received approximately $30 billion in January 2003 from
bond maturities, coupon income and proceeds from early redemptions.
However, these positive demand factors were not totally able to
offset the increase in tax-exempt new-issue supply, preventing more
significant declines in tax-exempt bond yields. This modest
underperformance has served to make municipal bonds a particularly
attractive purchase relative to their taxable counterparts.
Throughout most of the yield curve, municipal bonds have been able
to be purchased at yields near or exceeding those of comparable
Treasury issues. Compared to their recent historical averages of
82% - 88% of U.S. Treasury yields, municipal bond yield ratios in
their current 95% - 105% range are likely to prove attractive to
long-term investors.

Declining U.S. equity markets and escalating geopolitical pressures
have resulted in reduced economic activity and consumer confidence.
It is important to note that, despite all the recent negative
factors impeding the growth of U.S. businesses, the U.S. economy
still grew at an approximate 2.50% rate for all of 2002, twice that
of 2001. Similar expansion is expected for early 2003. Lower oil
prices, reduced geopolitical uncertainties, increased Federal
spending for defense, and a likely Federal tax cut are all factors
which should promote stronger economic growth later this year.
However, it is questionable to expect that business and investor
confidence can be so quickly restored as to trigger dramatic,
explosive U.S. economic growth and engender associated, large-scale
interest rate increases. The resumption of solid economic growth is
likely to be a gradual process accompanied by equally graduated
increases in bond yields. Moderate economic growth, especially
within a context of negligible inflationary pressures, should not
greatly endanger the positive fixed income environments tax-exempt
products currently enjoy.



MuniYield Michigan Insured Fund II, Inc., April 30, 2003


Specific to Michigan, the state maintains the highest possible
credit ratings of Aaa and AAA from Moody's and Standard & Poor's,
respectively (although with a negative outlook from both), and is
rated AA+ by Fitch. Michigan ranks 33rd in debt per capita and 35th
in debt as a percentage of personal income nationally. These ratios
are quite low for a populous state and indicate flexibility in
responding to economic downturns relative to other states. In line
with the national economy, revenues have consistently fallen below
state projections with even recent projections off by 15% compared
to actual revenues. Accordingly, the state has resorted to drawing
down on its Budget Stabilization Fund, from $1 billion in fiscal
year 2001 to under $100 million to date, as well as revenue
enhancements, such as the sale of state property and expenditure
reductions, including delaying capital projects, in order to balance
its current budget. For the first time in six years, Michigan will
issue cash flow notes in the amount of more than $1.2 billion during
May 2003. The state's new governor, Jennifer Granholm, faces a
projected $1.6 billion budget shortfall for fiscal year 2004. This
fiscal deficit will likely be addressed by delaying scheduled state
employees' pay raises and a hiring freeze, utilizing the Michigan
Economic Development Corp. for revenue enhancement, further delaying
state capital projects, and repealing business tax cuts.


Portfolio Strategy
Portfolio activity during the six-month period ended April 30, 2003
was limited and largely focused on adding higher-yielding, corporate-
backed issues to the Fund's holdings. The resultant increase in
dividend income should allow the Fund to maintain its attractive
dividend throughout 2003. Current general market municipal bond
yields have not proven to be historically attractive long-term
investments. Our strategy has been to purchase insured state general
obligation bonds and their equivalents rather than unenhanced
general obligation bonds since virtually no spread is evidenced. As
Michigan's economy continues to weaken, we believe credit
deterioration will lead to better relative performance of the
insured bonds. This was another reason for our focus on lower-rated
issues, which continue to trade at historically attractive yield
spreads. When the U.S. economy recovers in the future, these higher-
yielding issues are expected to retain more of their market value
than higher-rated, general obligation issues. The overall credit
quality of the Fund remained high. At April 30, 2003, over 85% of
the Fund's assets were insured and rated AAA by at least one of the
major rating agencies.

We recently adopted a slightly more defensive market position than
the one held in 2002. It is expected that a number of positive
economic factors, such as those previously mentioned, will result in
stronger U.S. economic activity later this year and into 2004. We
also expect that increased Federal borrowing, both to replenish
recent defense expenditures and offset reduced tax receipts, will
put modest upward pressure on interest rates in the coming months.
Upon signs of a material, sustainable economic recovery, a more
defensive portfolio strategy will be adopted to preserve recent
gains in the Fund's net asset value.

Throughout the period, the Fund's borrowing costs remained in the
1% - 1.5% range, with interest rates presently near 1%. These
attractive funding levels, in combination with a steep tax-exempt
yield curve, continued to generate significant income benefits to
the Fund's Common Stock shareholders. We do not expect any material
reduction in the Fund's borrowing costs in 2003 as no additional
easings by the Federal Reserve Board are anticipated. We expect the
Fund's short-term borrowing costs to remain at current attractive
levels for the coming months. However, should the spread between
short-term and long-term interest rates narrow, the benefits of
leverage will decline and, as a result, reduce the yield paid on the
Fund's Common Stock. (For a more complete explanation of the risks
and benefits of leveraging, see page 1 of this report to
shareholders.)

NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
MuniYield Michigan Insured Fund II, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a non-diversified,
closed-end management investment company. The Fund's financial
statements are prepared in conformity with accounting principles
generally accepted in the United States of America, which may
require the use of management accruals and estimates. These
unaudited financial statements reflect all adjustments, which are,
in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are
of a normal, recurring nature. The Fund determines and makes
available for publication the net asset value of its Common Stock on
a weekly basis. The Fund's Common Stock is listed on the New York
Stock Exchange under the symbol MYM. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, which are traded on
exchanges, are valued at their closing price as of the close of such
exchanges. Options written or purchased are valued at the last sale
price in the case of exchange-traded options. In the case of options
traded in the over-counter-market, valuation is the last asked price
(options written) or the last bid price (options purchased).
Securities with remaining maturities of sixty days or less are
valued at amortized cost, which approximates market value.
Securities and assets for which market quotations are not readily
available are valued at their fair value as determined in good faith
by or under the direction of the Board of Directors of the Fund,
including valuations furnished by a pricing service retained by the
Fund, which may utilize a matrix system for valuations. The
procedures of the pricing service and its valuations are reviewed by
the officers of the Fund under general supervision of the Board of
Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio investment strategies both to increase the return of the
Fund and to hedge, or protect, its exposure to interest rate
movement and movements in the securities market. Losses may arise
due to changes in the value of the contract or if the counterparty
does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
financial futures contracts and options on such futures contracts.
Futures contracts are contracts for delayed delivery of securities
at a specific future date and at a specific price or yield. Upon
entering into a contract, the Fund deposits and maintains as
collateral such initial margin as required by the exchange on which
the transaction is effected. Pursuant to the contract, the Fund
agrees to receive from or pay to the broker an amount of cash equal
to the daily fluctuation in value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Fund
as unrealized gains or losses. When the contract is closed, the Fund
records a realized gain or loss equal to the difference between the
value of the contract at the time it was opened and the value at the
time it was closed.

* Options--The Fund is authorized to write covered call options
and purchase put options. When the Fund writes an option, an
amount equal to the premium received by the Fund is reflected as an
asset and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written.

When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

* Forward interest rate swaps--The Fund is authorized to enter into
forward interest rate swaps. In a forward interest rate swap, the
Fund and the counterparty agree to pay or receive interest on a
specified notional contract amount, commencing on a specified future
effective date, unless terminated earlier. The value of the
agreement is determined by quoted fair values received daily by the
Fund from the counterparty. When the agreement is closed, the Fund
records a realized gain or loss in an amount equal to the value of
the agreement.

(c) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Realized gains and losses on security
transactions are determined on the identified cost basis. Dividend
income is recorded on the ex-dividend dates. Interest income is
recognized on the accrual basis. The Fund amortizes all premiums and
discounts on debt securities.

(e) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

MANAGED DIVIDEND POLICY


The Fund's dividend policy is to distribute all or a portion of its
net investment income to its shareholders on a monthly basis. In
order to provide shareholders with a more consistent yield to the
current trading price of shares of Common Stock of the Fund, the
Fund may at times pay out less than the entire amount of net
investment income earned in any particular month and may at times in
any month pay out such accumulated but undistributed income in
addition to net investment income earned in that month. As a result,
the dividends paid by the Fund for any particular month may be more
or less than the amount of net investment income earned by the Fund
during such month. The Fund's current accumulated but undistributed
net investment income, if any, is disclosed in the Statement of Net
Assets, which comprises part of the Financial Information included
in this report.
