Species Account

Sutton & Beaumont, 1989: Undoubtedly the most numerous and widespread species in the list so far!' (PQW). This is one of the commonest moths in August, often abundant throughout all five vice-counties and often a nuisance in light traps. For example, on 16.8.1987, 1,852 moths of this species were trapped at MV light in one evening! (BRS) and W. Reid estimated a catch exceeding 3,500 individuals on several unusually productive nights in Sheffield in 1955 (Reid, 1955). This species exhibits a very wide range of colour forms but dark varieties are not particularly common.

2012 (CHF): Still the commonest species, widespread across the county in big numbers. Numbers in the autumn may be swollen by migration.
