Nationally scarce (Na) in saltmarshes along the southern and eastern coasts of England, from Devon to south-east Yorkshire, largely absent from the west coast. In Hampshire and on the Isle of Wight occurs on the saltmarshes around the three harbours in the south-east of the county and on the north-west coast of the Island. Wingspan 10-15 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 Sea Aster, living within a movable case. The case is similar to that of C. virgaureae.
