Caterpillars are the larvae of moths and butterflies which belong to the large order of insects, Lepidoptera. There are 180,000 known species. Lepidoptera larvae eat foliage, buds, cambium, fruit and roots. Some species, such as the gypsy moth, are highly destructive and can completely defoliate a tree. Successive years of defoliation from caterpillars will weaken a tree and often lead to its death. Feeding damage from caterpillars is most often represented by chewed and/or consumed leaves. Often, the best indicator of caterpillar infestation is the presence of the caterpillar itself.
