ECLOSION, SCENTING AND MATING:
Males use their more highly 
developed antennae to seek out females who release an airbourne 
pheromone into the night sky.
EGGS, LARVAE, COCOONS AND PUPAE:
Eggs are deposited in 
clusters of 6-40+ on hostplant twigs.  Larvae have urticating spines 
and are gregarious, especially in the early instars. 
Larval Food Plants
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.
