Occurs in a range of habitats, including suburbia. This species rests by day on stone walls and rocks.

The flight time is during July and August, and the adults, which vary somewhat in size, are frequent visitors to light.

The larvae feed on lichens, especially rock-growing species like Lecidia confluens.

Fairly common over the larger part of Britain, it is somewhat more local in Scotland.  In a recent survey to determine the status of all macro moths in Britain this species was classified as common.
