Natural Habitat

Gardens, urban areas, woodlands, and other places where tree-of-heaven or related plants grow, especially across the southern United States and Central America.

Diet & Feeding

Caterpillars feed on leaves and shoots of mostly Simaroubaceae plants, including tree-of-heaven; adults drink flower nectar.

Behavior Patterns

Adults are primarily nocturnal and rest with wings folded roof-like, exposing orange-red and black markings. Several generations may occur annually in warm climates.

Risks & Benefits

Harmless to people and not medically significant. Larvae can damage host plants, while adults serve as minor pollinators and prey for other animals.
