July Belle Scotopteryx luridata
Wingspan 32-38 mm.
Very similar in appearance to Lead Belle (Scotopteryx mucronata), some examples can only be separated by genitalia examination.
The single generation flies in from June to August, and the species inhabits open heathland, downland and similar localities.
The larvae feed on gorse (Ulex) and petty whin (Genista anglica).
