Larvae feed at dusk and at night on Hamelia patens, Psychotria chiapensis, Psychotria horizontalis, Psychotria microdon, Psychotria pubescens, P. hebeclada and Palicourea grandifolia in the madder family (Rubiaceae). During the day, larvae hide near the base of their hosts or in surrounding vegetation.

Moths emerge from pupae in 14-25 days.
