Spongy Moths

The Lymantria dispar dispar (LDD) is a major forest pest concern because the caterpillar, or larva stage of the insect, eats the leaves of trees, defoliating them which makes them more susceptible to disease and damage from other insects, like tent caterpillars. Continued defoliation of trees can lead to their decline and eventual death. While this pest can consume the leaves of most trees, it tends to feed mostly on Oak, Cherry, Birch, Beech, Spruce, and Pine.
