Similar species: 1760 Red-green Carpet. For further information refer UK Moths.

Davey, P., 2009: A species occurring widely in northern and western Britain, but local and decreasing in the south and east, the larva feeding on sallow (Salix spp.) and birch (Betula spp.). This species has a similar life-cycle to the Red-green Carpet1760 in the adult stage, with females on the wing during the spring months only. In Dorset, old records exist from damp habitat on chalky and clay soils: Norden, female at rest inside porch on 15 January 1902, and Corfe Castle, at ivy blossom on 13 November 1891 (Reverend E Bankes), Milton Abbey, two at MV light on 14 October 1965 (H Edmunds), Iwerne Minster, at MV light on 20 October 1956, 27 August 1959,6 September 1959, 11 November 1965 (H Moore), Chamberlaynes, at honeycomb on 20 September 1935, 21 September 1935, 26 September 1935, 28 September 1935, 3 October 1935, 14 October 1935, 15 October 1935, at light on 17 October 1938 (H Andrews).

The species has decreased dramatically in recent years in south-east England, and it was doubted whether it still occurred in Dorset, however, a single moth was discovered at Alners Gorse, on 13 April 2006 (P Butter).

Care is needed in identifying potential Autumn-green Carpet as they closely resemble Red-green Carpet1760. Diagnostics include: pale ground colour with no reddish colouration plus whitish hindwings.
