Species Account

Davey, P., 2009: A rare species that has declined since the 1950s in southern England, still headquartered in the New Forest but more scarce there than the Light Crimson Underwing2454, the larva feeding nocturnally, firstly on the buds, and then on the foliage of oak (Quercus spp.). In Dorset, nine moths have been recorded, and seven of these on just three occasions were coincident with south-easterly airflows from central France, the 2005 record was more likely to have been a dispersed example from the New Forest transported on light east to north-easterly winds. The status of the moth in the county is therefore chiefly that of a rare immigrant. The following are from light traps unless stated otherwise: Weymouth, at study window pane in July 1880 (A Pickard Cambridge), on 11 August 1986 (M Parker), Portland, on 11 August 1986 (R Bell), Preston on 2 August 2004 (R Lambert), Durlston, on 9 August 2005 (D Brown), Swanage, at sugar on 21 July 1934 (A Russell), Scar Bank, at sugar on 20 July 1934 (A Russell), Studland, at sugar on 21 July 1934 (A Russell).
