Hoary Footman Eilema caniola
Wingspan 28-35 mm.
Paler and greyer than similarly patterned 'footmen', the range of this moth is more or less restricted to the south-west coasts of England and Wales, although occasional specimens do turn up further east along the coast, and sometimes inland.
The normal flight period is between July and September, and the adults are attracted to light.
Occupying rocky seaside cliffs and shingle beaches, the larvae feed on lichens growing on rocks.
