A day-flying moth, preferring sunshine and taking short, rapid flights. The English name refers to the forewing markings, which appear to show an old lady or witch's head.
Inhabiting waste ground, downland and other open habitats, it is reasonably common over much of the British Isles, becoming scarcer in Scotland and Ireland.
It flies in May and June, and the larvae feed mainly on clover (Trifolium) and various grasses.
