Status insufficiently known (thought likely to be a future Red Data Book species), Found in woodland in parts of Britain, although distribution poorly know due to having previously been lumped with E. regificella and only recognised as a separate species in 2001, when the two species were split. In Hampshire known to occur in a few woods in the south of the county, including Havant Thicket and Crab Wood, Sparsholt. Not recorded from the Isle of Wight to date. Wingspan 7-9.3 mm. Larva mines leaves of Hairy Wood-rush. Probably more widespread than the extent of available records indicate, due to its relatively recent discovery.
