Caterpillars affect many garden plants. Caterpillars are one stage of moths and butterflies. In large numbers, even small caterpillars can cause extensive damage to leaves.
These 1/2" — 3/4" caterpillars eat ornamental and fruit trees, shrubs, perennials, annuals, bulbous plants, and roses. These are the caterpillars of moths such as Archips argyrospila. They feed on apples, oaks, quinces, and roses. Pandemis limitata attack many trees and shrubs.
They graze away the inner surfaces of leaves and are generally a greenish color with a brownish head. When disturbed they wriggle backward rapidly.
