North American Ecology (US and Canada)

Hamadryas guatemalena is found in North America only as an occasional stray in to s. Texas from Mexico; it ranges south to Costa Rica (Scott 1986). Habitats are tropical open areas with trees. Host plants are restricted to one vine species: Dalechampia scandens (Euphorbiaceae) in Central America. Eggs are laid on the host plant singly, or in a stack of two or three. There are multiple flights all year in Mexico (Scott 1986).
