Davey, P., 2009: A widespread species in Britain, the larva feeding nocturnally on the roots of Compositae species including dandelion (Taraxacum spp.) and hawk's-beards (Crepis spp.). In Dorset, the moth is frequent to common on dry unimproved grassland on chalky and sandy soils; it is at low density or absent within woodland and wetland. The moth is double-brooded in the county, with a second generation between mid July and mid August; however, the following light trap records suggest a very occasional partial second generation: Puddletown, on 13 September 2000 (H Wood Homer), Gillingham, on 17 September 1997 (G Hopkins), Winterborne Stickland, on 15 September 2002 (L de Whalley), Gaunts Common, on 18 September 1983 (Miss M Brooks), Matchams, on 8 September 1983 (G Le Pard).
