Nationally scarce (Nb) in chalk downland and freshwater margins in parts of southern England and southern Wales. In Hampshire mainly confined to the south-east, with just a handful of records in the north of the county and on the Isle of Wight. Wingspan 12-16 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 Ploughman's-spikenard and Common Fleabane, living within a movable case.
