Moore (1957) gave a detailed account of the biology. Larvae are saprophagous and feed on dying or dead leaves of eucalypts which they skeletonise. Females oviposit in eucalypt leaves or in grass blades in close proximity to suitable food for larvae. The life cycle lasts, depending on temperature conditions, from 3 to 6 months. In the study area near Sydney, adults are on the wing from August to May. Males and females can be seen flying among leaves of felled trees, with females closer to the ground than the males. Females feign death when disturbed. Eggs are placed into the leaf margin in rows of up to 30. Larvae hatch after 1-2 weeks and feed mostly at night, but also during the day on cloudy days. The black cocoons are attached to sticks, rocks, rotten leaves, etc. The species is polyvoltine.
