Nationally scarce (Na) in lowland Calluna heathland, moorland, pine woodland and sheltered rock ledges up to 600 m in the Scottish Highlands, from Perthshire to East Ross (MBGBI Vol 3). Unlikely to be recorded in Hampshire or on the Isle of Wight. Wingspan 10-14 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 Cowberry, living within a movable case, over-wintering twice.
