ECLOSION, SCENTING AND MATING:

Females extend a scent gland from the tip of the abdomen, and the night-flying males pickup and track the airbourne pheromone plume with their well-developed antennae.

Females are likely most active right after dusk. The male, above, was taken early in the evening.

Eggs are deposited in clusters on hostplant foliage.

Hirpida mavanschaycki larvae are highly gregarious and have the urticating spines typical of larvae from the Subfamily Hemileucinae.

The species name is honourific for Manfred van Schayck.
