They are large-bodied moths with a 4 to 5 inch wingspan that resemble humming birds in flight as they hover around flowers from which they obtain nectar at dusk. The moth's abdomen is marked with five pairs of orange-yellow spots. Female moths deposit greenish-yellow eggs single on the undersides of host plant leaves. Unless the pupa over-winters, adults can emerge in about 3 weeks, producing two generations per year. Caterpillars have chewing mouthparts.
Adults have siphoning mouths.
Caterpillars feed of leaves of tomato, eggplant, pepper, potato and some weeds. Adults are attracted to lights. For additional information, contact your local Texas extension service agent, or search for other state extension service offices.
