Local on saltmarshes, waste ground and farmland in England and Wales, as far north as Co. Durham, and the Isle of Man (MBGBI Vol 3). In Hampshire largely restricted to the south-east coast, but there are a few inland records identified through dissection that indicate it is very likely to be more widespread than records suggest. Certainly, detailed work on the Isle of Wight since 2020 has indicated that it is likely to bre relatively common and under-recorded. Wingspan 11-15 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 href="lep.php?code=37.083">
