Genus:Notodonta
Species:tritophus
Authority:([Denis & Schiffermüller], 1775)

Very rare immigrant (less than 10 previous UK records) from mainland Europe, appearing in southern England. First recorded in Britain in Bedfordshire in 1907, with a total of ten in the 20th Century, subsequently recorded in Kent in 2004 and 2006. In Hampshire recorded at Havant and Waterlooville in 1920. On the Isle of Wight, recorded at Freshwater in 1956 and Cranmore in 1960. Wingspan 54-62 mm. Although fairly distinctive, could be confused with both Iron Prominent N. dromedarius and Pebble Prominent N. ziczac, and it is unlikely that records of this species will be accepted unless the specimen is retained for examination. Larva feeds on Aspen, Black Poplar and White Poplar, no evidence of breeding in the UK.
