Often at light in Ipswich; abundant at Beccles; Gorleston. Unnoted in west Suffolk up to 1890, though actually frequent in the Breck marhses, where it feeds on any Salicineae; pupae at Rushbrook (Norgate); larvae common on osiers at Sudbury in spring of 1898 (Ransom).
Recent Suffolk status: Locally common.
