Status and ecology:

National Status: Nb

This resident species is extremely local and in East Sussex the moth usually occurs sparingly at mv light and sugar, but is sometimes fairly common or even common on vegetated shingle beaches and near chalk cliffs within sound of the sea between Newhaven and Pevensey and at Lewes and Rye. This species is presumed extinct in West Sussex since 1953. Single-brooded flying mainly from the second week of August to late September, but occasionally from late July. The larval foodplant is not known in this country. (Pratt, 2011)
