Endangered (proposed as a future Red Data Book species) in mountains and on limestone pavements in the central highlands of Scotland around Braemar and on the Burren in Ireland. Unlikely to be recorded in Hampshire or on the Isle of Wight. Wingspan 11-13 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 feeds on seeds of Mountain Everlasting, living within a movable case.
