Pest Type: Insect
Damage to Plant: Fruit is tunneled and often drops prematurely; the caterpillar may still be inside.
This 1 inch long caterpillar, with a white or pinkish body and a dark head, is one of the most stubborn orchard pests. The damage is worse during warm, dry springs.
Life Cycle: Coppery-banded moths lay eggs in spring when host trees are in bloom. After hatching, caterpillars tunnel to the core of the developing fruit or nut. They eventually burrow out, leaving excrement, then drop to the ground or crawl down the trunk to pupate in cocoons under loose bark or in debris. There are two to four generations a year.
