The passion flower vine outside our kitchen window is a host plant for the caterpillar stage of this butterfly. Males patrol for females, who lay eggs on many parts of the host plant.
Caterpillars feed on most parts of the host.
Adults overwinter in the south. Throughout the year in south Florida and South Texas, January-November in the north. Number of broods has not been determined. Nectar from lantana, shepherd's needle, cordias, composites, and others. South America north through Central America, Mexico, and the West Indies to the southern United States.
