Nationally scarce (Nb) in hedgerows and heathland throughout much of Britain, but not in northern Scotland. In Hampshire continues to be recorded very infrequently, latterly at Botley Wood in 1990. Not recorded from the Isle of Wight to date. Wingspan 12-14 mm. Like many of the Coleophora, imagines are virtually impossible to identify without recourse to dissection, and the larvae, which live in cases of characteristic form and which can sometimes be found on the foodplant, may be easier to identify by comparison against a reference collection. Larva mines leaves of Birch, Hawthorn, Apple and Rowan, living within a movable case, over-wintering twice.
