Season
Two annual generations over much of its range. Adults are present in May to June and again in August.
Food
In addition to feeding on various stone-fruits, larvae have also been recorded feeding inside galls.
Life Cycle
Females lay eggs singly on young fruits or on the upper surface of leaves. Lavae tunnel into the fruit at the calyx end and feed inside. In apple, larvae may feed directly under the skin of the fruit, creating a blotchy mine. Overwintering occurs as a mature larva and pupation occurs in the spring.

This is one of the smallest North American tortricids. Fresh specimens are unlikely to be confused with any other species.
