Spongy Moths Are Making A Comeback in Vermont
Many Vermonters around the state are encountering spongy moth (Lymantria dispar dispar or LDD) caterpillars causing defoliation of their trees. This invasive insect arrived in the United States over 100 years ago and has been expanding its range ever since. Spongy moth can be a significant defoliator (leaf eater) of trees and shrubs, and although they prefer oak trees, high populations will cause them to eat many types of leaves, including maple and pine. Spongy moth caterpillars can create a nuisance for homeowners, from the sights of caterpillars climbing the sides of residences and falling frass to the sounds of chewing on leaves.
