Four-spotted Footman Lithosia quadra
Wingspan 35-55 mm.
This sexually dimorphic species is resident along the south-west coast of England and Wales, and is also an occasional immigrant.
Only the females have the spots which give the species its name; often there appears to be only three spots, as the wings overlap when at rest.
The larvae feed on lichens on the bark of deciduous trees.
It flies from July to September.
