Maple Pug Eupithecia inturbata
Wingspan 13-15 mm.
One of the smaller 'pug' moths, this species is relatively scarce, though distributed over the larger part of England and Wales.
It occupies a variety of wooded and semi-wooded habitats, and the larvae feed on the flowers of field maple (Acer campestris).
The adults are on the wing in July and August and come to light.
