FLIGHT TIMES AND PREFERRED FOOD PLANTS:

A single specimen has been taken in July. There are probably additional flight months.

Larvae feed upon West Indian Locust (Hymenaea courbaril) and West Indian Cedar (Cedrela odorata).

ECLOSION, SCENTING AND MATING:

Males use highly developed antennae to locate females at night by tracking their airbourne pheromone plumes.

EGGS, LARVAE, COCOONS AND PUPAE:

White eggs with a black micropyle are laid in large clusters and larvae feed gregariously.

Typical of the Subfamily Hemileucinae, Dirphia species all have urticating spines.

The species name is indicative of a close similarity to Dirphia horca and a specimen type locale in Amazonas, Peru.

It is hoped that this alphabetical listing followed by the common name of the anticipated foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.
