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 are reported to feed on Ficus microcarpa, Ficus prinoides, Ficus ovalis and Artocarpus integrifolia in Brazil.

Jean Haxaire: "Moraceae. Moss (1920) has reared it on Artocarpus integrifolia and Cecropia sp. In Costa Rica, on species of Ficus spp."

In the early instars, larvae greatly resemble Pseudosphinx tetrio or a coral snake. They thrash about when disturbed and also "squeak".
