Davey, P., 2009: An unimproved grassland and unimproved arable species in Britain, the larva feeding on the seeds of grasses (Poaceae spp.) and the seeds of cereal crops such as wheat, rye, oats and barley. In Dorset, the moth is widespread and frequent, and has been trapped in every month except December and January. It is locally common in unimproved grassland and most often recorded in coastal areas. The species was undoubtedly abundant on arable in the days before toxins were applied to every last square metre of crop, for example, the caterpillar was found in large numbers on Purbeck by beating haystacks. The national norm is of a bivoltine cycle, but in Dorset the picture is not nearly as clear-cut with a pattern reminiscent of immigrant species such as the Turnip2087 where populations increase through the year, being supplemented by immigration from Europe.
