Davey, P., 2009: Found throughout Britain in most habitats, the larva feeding nocturnally on most plant species. In Dorset, the moth is ubiquitous and frequent, increasing to common in open areas and amongst scrub. The flight period between July and September holds true, although singletons have been trapped as early as mid-May and as late as early November. Aestivation may account for the dip in numbers in the middle of August, see phenology chart. The following light trap records are of single night catches in excess of fifty moths, all noted from coastal localities. Unusually high numbers of Large Yellow Underwing2107 were noted on the same dates: West Bexington, 53 on 6 August 1994 (R Eden), St Albans Head, 150 on 7 August 1992 (P Davey), Durlston, 100 on 29 July 1992, 65 on 26 July 2006 (P Davey).
