The males have triangular grey-brown forewings with dark-edged jagged crossbands which are distinctively held overlapping at rest. The females are completely wingless with a barrel-shaped body and a tuft of hairs on the end of the abdomen. The adult males fly after dark and are attracted to light in March and April.

The light green caterpillars can be found from late April to June overwintering as pupae in a fragile cocoon under the ground.
