Davey, P., 2009: A species occurring throughout Britain, the larva feeding on hawthorn (Crataegus monogyna), sallow (Salix spp.) and various herbaceous plants. In Dorset, the moth is at low density, ubiquitous and more frequently observed at sugar bait than at light traps, although it seems to have declined in recent years. Unusually high numbers of adults were trapped in the last few days of July 1995 (see graphic), and immigration from north-east France or sources further east in northern Europe is suspected on this occasion. Unusually high numbers of Least Yellow Underwing2112 moths were also recorded at this time. Relatively high numbers were also noted in 1992 and 1994 at light traps. Maximum counts recorded in 1992, 1994 and 1995 are as follows: West Bexington, fifteen on 6 August 1994, sixty-six on 30 July 1995 (R Eden), Fontmell Down, eighteen on 30 July 1995 (P Davey), St Albans Head, seventeen on 7 August 1992 (P Davey), Durlston, twenty-one on 7 August 1992 (P Davey).
