Memorial Day Weekend means hitting the road for many of us – vacations, camping, or even moving to a new home. But watch out for an invasive pest that also enjoys new destinations—the destructive gypsy moth. Gypsy moth caterpillars can defoliate, weaken and kill more than 300 different species of trees and shrubs. Since 1970, more than 83 million acres have been defoliated by the gypsy moth in the U.S.

While being outside in Massachusetts this June, I first noticed it.  A lot of leaves were falling from the trees, only these were chewed leaf parts, not whole leaves.

Similar to the children's book, The Very Hungry Caterpillar written by Eric Carle, some leaves didn’t just have chew marks but actual holes going straight through them.  Unlike the children’s book, this damage isn’t being caused by a friendly caterpillar who turns into a butterfly.  Instead it’s the result of ravenous gypsy moth caterpillars feeding…and feeding.  It’s so bad that in some areas, on walkways and roadways, it looks like fall.  Brown, dried up leaves are a contrast to summer’s lush greenery.
