The habitat consists of subtropical forests and forest edges, scrubs, roadsides and pastures.
The wingspan is 38–51 mm (1.5–2.0 in). Adults are on wing from April to November in southern Texas and northward. They are on wing year round in the tropics. Adults feed on flower nectar.
The larvae feed on Cassia species.
