They fly at night so most people rarely notice them.
Eggs are light green and dome shaped.
In May the moths emerge from overwintering pupae and lay their eggs on the upper surface of leaves. The larvae feed for 2-4 weeks, then pupate for 10 days in thin silk cocoons attached to stems or leaves. There are three to four generations per year in most areas. Spray severe infestations with garlic oil, pyrethrin, ryania, or sabadilla.
