Davey, P., 2009: A widespread species in Britain, the larva feeding on various herbaceous plants and, unlike their cogeners after hibernation, do not ascend to feed on the young foliage of shrubs and trees during the spring. In Dorset, the moth is common for the most-part, and rises to abundant on unimproved grassland habitat irrespective of geology or moisture levels, and falling to low density in woodland and on core heathland. The two broods are of similar magnitude.
