Species Account


Similar species: 1764 Chloroclysta truncata (Common Marbled Carpet).

For further information refer UK Moths.

Davey, P., 2009: A local species in southern England but widespread elsewhere, the larva feeding on sallow (Salix spp.), birch (Betula spp.), bilberry (Vaccinium myrtillus) and wild strawberry (Fragaria vesca) In Dorset, the moth is local, occurring on chalky soils in central and north-east Dorset, typically in open woodland such as Stubhampton Bottom where it is frequent, and on the Purbeck Ridge where it is very local. Elsewhere, it is found in the west of the county in open woodland on clay soil, for example, Powerstock Common and Hooke Park. It is absent from sandy soils.

Care is needed in identifying this species as it closely resembles the Common Marbled Carpet1764, and both species have many colour forms. Diagnostics include: a single-brooded species and on the wing between the first and second broods of the Common Marbled Carpet1764; the angle made by the post-median line where it turns on the fore-wing is acute but on the Common Marbled Carpet1764 tends to be obtuse.

Hill, L., 2013:

Ignore the many colour forms which can add to confusion. The underside hindwing diagnostic should be referred to in all cases; on Dark Marbled Carpet the hindwing underside postmedian line turns sharply and is usually acutely angled, it is more rounded and obtusely angled on Common Marbled Carpet.
