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:

Larve feed gregariously and have urticating spines.

The species name, roseobasalis, is indicative of a rosy tint in the hindwing basal area.

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