Notes:
Local on rough grassland and waste ground, although the exact status and distribution of this species is unclear due to past confusion with C. frischella, which is very similar and can only be separated through dissection of the genitalia. In Hampshire there have been a few confirmed records, mainly in the south-east, with five at Sherborne St John in the north of the county. Not recorded from the Isle of Wight to date. Wingspan 11.5-14.5 mm. Larva feeds within seedheads of White Clover, living within a movable case.
