Nationally scarce (Nb) in saltmarshes, waste ground, farmland and fens throughout much of England and Wales, south of a line from The Wash to the Mersey estuary (MBGBI Vol 3). In Hampshire largely restricted to the south-east coast, with just a few inland records, including one in northern Hampshire, at Greywell in July 2004. Not recorded from the Isle of Wight to date. Wingspan 13-16 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 feeds on seeds of Grass-leaved Orache and Sea-purslane, living within a movable case.
