Identification. The larvae are light brown to yellow green with a brown head. Full grown larvae are ¾-inch long, but can be as small as a 2-3 mm. When disturbed, they wiggle backwards and drop to the ground on a silken thread. Rolled leaves webbed together form a protective nest indicating the presence of leafroller larvae. Adult moths are tan or gray with darker mottling on the forewings.
Life Cycle. Overwintering in canes and dried leaves, larvae may feed during winter warm periods, but become active in spring. Adult moths emerge in late spring to lay eggs. Hatch of 1st summer brood often coincides with harvest and therefore contaminates fruit. There are 3 or 4 overlapping generations a year.
