Davey, P., 2009: A species found throughout south-east England, becoming scarcer the further north and west one travels, the polyphagous larva feeding nocturnally and a noted pest species of cabbage crops (Brassicae spp.). In Dorset, the moth was: "a serious agricultural pest in gardens, market gardens and fields, and does at times serious damage to food for man and cattle - no cultivated land in the county where it cannot be found." (W Parkinson Curtis ms). Today this is certainly not true, and the species has undergone a dramatic decline, perhaps due to the widespread application of toxins on vegetable crops. It is best described as widespread but at low density, rising to frequent along the Purbeck coast and Portland where cabbage (Brassica oleracea) grows naturally on chalky cliffs and undercliffs. The species apparently overwinters either as a larva or as a pupa, the former producing broods from mid-June to early July and a main brood from mid-August to mid-September, and the latter producing moths between late May and mid-June, with a main generation between mid-July and mid-August. A bilateral gynandromorph was trapped at Hurn on 17 September 2003 (M Jeffes).
