Food
Larvae recorded feeding on several species of Blechum, Justicia, & Ruellia (Acanthaceae).
Also, reported from Petitia (Verbenaceae), Breadfruit - Artocarpus altilis (Moraceae), Cajon - Colubrina cubensis (Rhamnaceae), and Sea Grape - Coccoloba uvifera (Polygoniaceae), but these, particularly the last two seem unlikely.
Adults usually feed on rotting fruit, occasionally bird droppings and nectar.

Apparently all U.S. specimens are referable to subspecies biplagiata (Fruhstorfer).
