Western strawberry leafroller

Compsolechia fragariella

The adult is a reddish brown moth with distinctive yellow markings on the forewings, and has a wingspan of about 11-14 mm. Eggs are laid on leaves in clusters; they are translucent to pale green at first but turn yellowish as they reach maturity. They hatch in about 10 to 14 days. The larvae are pale green at first but change to grayish brown as they feed and mature. Mature larvae are about 12 mm long. The larvae roll and tie leaves together with silk for shelter and feeding, and wriggle and thrash about violently when disturbed. Larval feeding on buds can damage developing flowers which results in deformed fruit.
