Common Footman Eilema lurideola
Wingspan 28-35 mm.
A widespread species in most of Britain, except in Scotland where it is local. Quite common in the south of its range.
The forewings are greenish-grey, with a leading yellow stripe, tapering to a point at the tip. The wings are folded flat over the back when at rest. In flight, the yellow hindwings are noticeable, and it looks a much larger moth.
It is on the wing in July and August and frequently comes to light. The larvae feed on various lichens.
