First-generation larvae are active before and during bloom. Focus scouting on flower buds and look for webbed flowers and leaves. The summer generation larvae are active during fruit ripening, feeding on fruit and foliage. Larvae are green with a dark head and about 25 mm long when fully grown. They feed on flower clusters, leaves, and green fruit. Larvae feed inside webbing used to pull together plant tissues into a protective shelter and may be hard to find.

Pheromone traps can be used to determine adult emergence. This information can be combined with growing degree days to predict egg hatch, larval development, and optimal timing for control. Timing of treatment may depend on the type of insecticide.
