Gypsy Moth

2016
The Nature Conservancy and Southern Regional Extension Forestry
The European gypsy moth is firmly established in the eastern and midwestern U.S. and southeastern Canada. The Asian gypsy moth is not yet established in North America, but is occasionally intercepted at ports of entry. Both moth species look the same and have similar biology – the only difference being that adult female European gypsy moths cannot fly, whereas adult female Asian gypsy moths can. These moths have one generation per year, and larvae feed on hundreds of different tree species. Oaks are preferred, but caterpillars also utilize birch and poplar as food. Larval feeding can completely defoliate trees. A single defoliation event probably will not kill the tree, but multiple successive defoliations can severely weaken trees. Gypsy moths lay egg masses on nearly any surface – including cars and trailers – and this is a primary method in which gypsy moths are spread.
