Life cycle and behaviour

Eggs are laid on leaves close to the ground, hatch in the autumn, and the young larvae hibernate. The larvae feed on grasses, various shrubs and deciduous trees, such as oak, European beech, poplar and Calluna.{{citation needed|date=September 2022}} The cocoon is formed on the ground.

Adults' wingspan is 40–55 mm and it flies from June to September depending on the location (in Britain it is on the wing in August). They fly during the day, but also at night, and will come to a light. The female is larger than the male.
