Principally found in the east of the country from Norfolk to Kent, with recent evidence of an expansion westward in central and southern England. In Hampshire a colony in Emer Bog persisted for many years and may still remain, although there have been no reports since 1993. In recent years, particularly since 2020, it has been recorded annually from scattered localities across the county. Not recorded from the Isle of Wight to date. Wingspan 27-30 mm. Larva feeds on Hairy Wood-rush, Field Wood-rush and Sedge in fens, marshes, bogs and ditches, although there has been no direct evidence of breeding in our area.
