A vulnerable Red Data Book species, in reed-beds, in East Anglia. It was first recorded in the Norfolk Broads in 1961 with the existence of a colony at Hickling being confirmed by a number of sightings in the 1980s. Although it is now known from four 10km squares, the occupied sites are not large and are rather close together (MBGBI Vol 9). One was taken at light in Ashurst, New Forest, in 2023, presumed to have originated from the continent, but dispersal within the UK cannot be ruled out. Wingspan 25-30 mm. The most likely confusion species is
Dotted Footman P. muscerda, which see for differences. Larva feeds on various lichens.
