Fruit surface feeding by casebearer or bag moth caterpillars

 Casebearer (bag moth) caterpillars live within their conical cases from which they graze the surface of fruit or eat holes in the leaves. The edges of the damage to fruit is a series of small curves where the caterpillar has fed, and the healed depression caused by the feeding is often shiny in appearance. The caterpillars often feed at a number of discrete sites on the surface of a single fruit.
