Forest Tent Caterpillar Upper Midwest NA-PR-02-01

The forest tent caterpillar (FTC), Malacosoma disstria, is a native species found throughout hardwood forests of North America. It feeds on the leaves of many trees, but in Michigan, Minnesota and Wisconsin, outbreaks occur in aspen, birch, basswood and oakstands. Sugar maple is a favorite host in Michigan's Lower Peninsula, but is not highly preferred in other parts of the Midwest.  Regional outbreaks occur at 5-15 year intervals, each outbreak lasting 2-5 years. At the peak of an outbreak, millions of acres of trees can be stripped of their leaves by mid-summer.
