Very rare immigrant (less than 10 previous UK records) from mainland Europe, just one example has occurred in Britain, reared from an egg or larva found in north Norfolk in 1882. Not recorded in Hampshire or on the Isle of Wight to date. Wingspan 46-50 mm. Intermediate between
Iron Prominent Notodonta dromedarius and
Great Prominent Peridea anceps, it is unlikely that records of this species will be accepted unless the specimen is retained for examination. Larva feeds on Aspen, White Poplar, Black Poplar, Silver Birch and Downy Birch, no evidence of breeding in the UK.
