Davey, P., 2009: A widespread species in Britain, the larva feeding on a variety of plants, shrubs and trees. In Dorset, the moth is ubiquitous and common. The first brood is on the wing between late-May and early-August, in a rather protracted emergence period. A partial second brood has been noted in most autumns over the past quarter century. The national norm is for a single brood only between mid-May and mid-July. Extreme examples of variation tend not been noted in the county, however, an example where the usual buff ground colour was replaced by a strong cadmium tint was trapped at Scar Bank by A Russell. Recorded in 40 (100%) of 40 10k Squares. First Recorded in 1934. Last Recorded in 2019. (Data up to end 2019) |
