Description

Family: Erebidae (ABH : 72.063)

Wing span: 36 - 42mm

This moth has a rather slender body and fairly large wings. The head and collar are are dark brown, often appearing black. The forewing is a light pastel grey. There is a rather elongated kidney mark, and the oval is reduced to a dot.

It is found in most of England, excluding the south-west. It is largely coastal in south and west Wales, and almost absent from Scotland.

Habitats are unimproved damp pasture, water- and hay-meadows, fens, marshland, dry calcareous grassland, and damp woodland.

There is one generation in June and July. It overwinters as a small larva.

Larvae feed mainly on Tufted Vetch.

It is easily disturbed during the day, visits flowers, and comes to light.
