Old Lady Mormo maura

(Linnaeus, 1758)

---

Wingspan 55-65 mm.

A large-winged, sombre-coloured moth, which is distributed locally throughout much of Britain, and common in places.

It hides by day in old buildings and sheds, and frequents damp localities as well as waste ground and gardens.

The adults are not readily attracted to light, but are frequent at sugar, and are on the wing in July and August.

The rather plump caterpillars feed in the spring after overwintering, on blackthorn (Prunus spinosa), and other shrubs and trees.
