Lead Belle Scotopteryx mucronata
Wingspan 30-38 mm.
Locally common in much of Britain, this species inhabits moorland and heathland, and can be disturbed in the daytime from its resting places. In the northern parts there is a darker subspecies (scotica), which also has a melanic form.
There is one generation, flying in May and June.
The overwintering larvae feed mainly on gorse (Ulex) and broom (Cytisus).
