These attractive moths resemble a shrivelled leaf when resting, and are most commonly encountered during the winter when they can be found hibernating on the ceilings of dark outhouses, porches, cellars and caves. The legs and the underside are spotted with white which looks like the mould formations seen on rotting leaves.

In the autumn they visit ivy blossom and ripe blackberries, as well as being attracted to light.
