Common on heathland and moorland throughout the British Isles, becoming established even on isolated gorse bushes. Common and widespread in Hampshire and on the Isle of Wight. Wingspan 11-16 mm. Reminiscent of
C. splendana in general appearance but differs in its smaller size and the weaker ocellus of the forewing [Bradley]. Larva feeds within seedpods of Gorse and, less frequently, Dyer's Greenweed, Petty Whin, Broom and Bird's-foot Trefoil, over-wintering in a cocoon.
