Considering this, how is the gypsy moth harmful?
Gypsy moths do not kill trees directly they defoliate them. Severe defoliation can add to other stresses such as weather extremes or human activities. This cumulative stress can leave trees vulnerable to disease or other pest infestation that can cause death.
Gypsy moth females lay between 500 to 1,000 eggs in sheltered areas such as underneath the bark of trees. The eggs are covered with a dense mass of tan or buff-colored hairs. The egg mass is approximately 1.5 inches long and 0.75 inches wide. The eggs are the overwintering stage of the insect.
