Account: Previously considered to be widespread, in woodland, heathland, scrub, hedgerows and gardens, throughout much of the British Isles, but appears to have collapsed as a breeding species in the southern part of the country 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, and is double brooded: citrata has a limited flight period, in the literature generally quoted as running from June to August.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.
