SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen.

EGGS, LARVAE, PUPAE:

Larvae probably feed on Vitus tiliifolia and other members of the Vitaceae family: Vitis, Cissus rhombifolia, Ampelopsis. Tetracera volubilis, Curatella americana, Tetracera hydrophila and Doliocarpus multiflorus of the Dilleniaceae family likely also serves as a host, as does Ludwigia of the Onagraceae.

The "horn" is very long in early instars and head is relatively large. As the larva matures, the body develops rapidly, leaving the head relatively small and the "horn" relatively short.

The pupa is dark and smooth with a sharp cremaster.
