Local on waste ground, farmland and rough ground throughout much of the British Isles, but not in the Highlands or Islands of Scotland. In Hampshire widely distributed in small numbers, mainly inland; recorded once on the Isle of Wight, to light at Ventnor in August 1987. Wingspan 13-16 mm. Imago very similar to C. sternipennella, from which only reliably separated by dissection of the genitalia. Larva feeds on seeds of Orache and Goosefoot, living within a movable case. Case indistinguishable from those of C. sternipennella, C. versurella and C. vestianella.
