Common in rough grassland, downland and woodland clearings and in marshes and other damp places throughout much of the British Isles, except the Shetland Islands. In Hampshire and on the Isle of Wight rather infrequently recorded, with the usual concentration of records in the south-east of the county, probably under-recorded elsewhere. Wingspan 11-12.5 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 Common Bird's-foot Trefoil and Greater Bird's-foot Trefoil, living within a movable case.
