There are two to four generations each year. The fruittree leafroller overwinters in the egg stage. Hatching will occur about the time buds begin to open. Larvae feed on buds, blooms, leaves and fruits. In June, full grown larva transform into pupae, inside folded or rolled up leaves.
Moths appear in about two weeks, lay their eggs, and die.
Only one generation occurs each year. Overwintering of the obliquebanded leafroller occurs as partially grown larva inside tightly woven cases, on the host trees. During spring, larva emerge and resume feeding until late May. Pupation occurs and adults will emerge in June. One or two generations may occur each year. Damage is done by young larva mining the leaves, with larger larva feeding inside rolled up leaves or leaves attached to fruits.
