Davey, P., 2009: A cosmopolitan species north of the sub-tropics, and widespread in lowland Britain, the larva feeding on various herbaceous plants. In Dorset, the moth is ubiquitous and abundant. The species is double brooded with the peak of the second brood on average, more than three times greater than that of the first. Indigenous populations in northern Europe are reinforced with migrants from further south, sometimes influxes are huge, and in Dorset, large single night catches often coincide with notable immigration events. The following light trap records show instances of two hundred moths or more: Scar Bank, 500 on 28 August 1949 (A Russell), West Bexington, 273 on 18 September 2001 (R Eden), Puddletown, 745 on 24 September 2000 (H Wood Homer), Gaunts Common, 200 on 18 September 1992 (P Davey), Durlston, 200 on 2 September 1998 (P Davey).
