Davey, P., 2009: A species often associated with cultivated land and one of the most abundant moth species occurring in England and Wales, but becoming less frequent further north, the larva feeding on a wide range of plant species. In Dorset, the moth is ubiquitous and abundant. In favourable years trap totals are vast, for example, 19000 at Furzebrook in 1976 and 11000 at West Bexington in 1996. The national norm is for a single brood from mid-May to late July, but in Dorset the moth is bivoltine, and in ten of the past twenty-five years, potential third-brood individuals have been trapped during the second half of October. The period between the average theoretical brood peaks is roughly sixty days.
