Recent Suffolk Status: Rare. Scattered colonies across the county still including the Barton Mills area. Coastal records possibly migrants.

Life history: Single-brooded. Appears at light near known sites usually only singly. Has been found on Ivy blossom near to Poplar trees at Little Blakenham (N. Sherman, T. Prichard et. al.). Still recorded as larvae at Barton Mills, using the traditional technique of collecting fallen Poplar catkins in the spring and waiting for the young larvae to emerge from them which then feed on various low growing plants.

Identification: The hooked wing tip and white spot in the kidney mark distinguishes this species from Dusky-lemon sallow and Brick.

Habitat: Poplar plantations and avenues.
