FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Moths are observed in January-March, May, August-September and November (SB) - December, suggesting multiple broods.

Larvae feed upon Salix, Schinus terebinthifolius and Robinia pseudoacacia.

ECLOSION, SCENTING AND MATING:

Males use highly developed antennae to locate females at night by tracking her airbourne pheromone plume.

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.
