The adult moths have brown wings with scalloped edges. The females have thread-like antennae, a fat abdomen, and a wingspan of about 5 cms. The females have an obtuse angle at the tornus of each forewing.
The males have forewings that have nearly a right angle at the tornus. The males have feathery antennae, and a wingspan of about 4 cms.
The males often rest facing downwards on a tree trunk by day.
