Gypsy Moth Damage

This section provides examples of the damage gypsy moths do to trees.

More than 320,000 acres of trees were defoliated by gypsy moth caterpillars in New Jersey during the spring of 2007, the highest amount since 1990 when 431,000 acres of trees experienced leaf loss. Two or three consecutive years of significant defoliation (defined as 75 percent or more) can kill an otherwise healthy tree. However, any gypsy moth defoliation can make trees more susceptible to other damage that can lead to the death of the tree.
