Nationally scarce (Nb) in damp heathland, mosses, bogs, fens and other damp areas in parts of England. In Hampshire fairly frequent in the New Forest, on boggy heathland; away from there, it is known from the north-east where, in 1957, it was reported as being fairly common in the Farnborough area and was reported in the Rushmoor district in 2011 and again in 2022/2023. Not recorded from the Isle of Wight to date (where there is little suitable habitat). Wingspan 18-20 mm. Small size and day-flying habits could result in confusion with pyralids such as
Gold Triangle Hypsopygia costalis and
Pyrausta sanguinalis. Larva feeds on Marsh Cinquefoil.
