Found as larvae in Port Saint John (Cocoa), Florida, USA in September, 1997.  Larval foodplant is Mandevilla (an imported vine with pink or yellow flowers and milky sap).As with Syntomeida epilais, the larvae tend to be communal, staying in close proximity to each other, even when pupating.  The young larvae skeletonize the leaves on which they feed.  Eggs are laid in large rafts on leaf undersides.  If not controlled, one such cluster of larvae can consume an entire plant.  The cocoons are loosely formed and include the hair bristles, also as does Syntomeida epilais.
