Widespread, in woodland, heathland, scrub, hedgerows and gardens, throughout much of the British Isles. In Hampshire and on the Isle of Wight, rare but perhaps overlooked. Wingspan 32-40mm. The most likely confusion species is Common Marbled Carpet C. truncata
, but that species has a less acutely angled postmedian fascia on the hindwing, more obvious on the underside. Good photographs of both the upper AND underside or a specimen is required for this species to be considered for acceptance
. Larva feeds on Silver Birch, Downy Birch, Heather and Sallow, over-wintering as an egg or small larva.
