Local in grassland, downland, heathland and woodland rides throughout much of the British Isles. In Hampshire recorded from Pamber Heath and Botley Wood, with scattered records elsewhere in the county; there have been a few records from the Isle of Wight. Wingspan 10-13 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 Field Wood-rush and Heath Wood-rush, living within a movable case.
