Naturalised in aquatic nurseries through accidental introduction in aquatic plants from Maryland, U.S.A; first recorded breeding in Hemel Hempstead, Hertfordshire in 1967, subsequently found at Enfield, Middlesex. Not recorded in Hampshire or on the Isle of Wight to date. Wingspan male 14-16 mm, female 17-19 mm. One of several related species established through the horticultural trade, of which the main confusion species are P. diminutalis (different pattern on hindwing) and P. fluctuosalis (outer part of forewing banded with orange). Larva feeds on water plants, causing sufficient damage to be a serious pest in some areas.
