Where to Look

Inspect the young leaves for signs of silken webbing and rolled leaves. Open these leaves and look for the caterpillar and sign s of chewing damage on the leaf surface.

The female lays eggs in masses on the young leaves. Each mass may have 8-22 eggs. The caterpillar feeds for about 4 weeks and then pupates inside the rolled leaf. In favorable climates there may be three to four generations each year.
