Identification

Habitat
Tropical and subtropical lowland environments; associated with forest edges and disturbed where larval plants occur.

Primarily Neotropical, ranging from Mexico through Central America to South America. Records from southern Florida and South Carolina represent vagrant or peripheral .
Similar Taxa
- AelloposSimilar size and wing shape; both in Dilophonotini, but Aellopos have more uniform dark forewings and different abdominal patterning.
- EupyrrhoglossumOverlapping distribution and ; Eupyrrhoglossum have more rounded wing apices and distinctively patterned hindwings.
