In Hampshire locally common in bogs in the New Forest, very local and occasional elsewhere; the first and so far only sighting on the Island was in 2015. Wingspan 22-26 mm. Most like C. pascuella, from which distinguished by the median streak extending beyond subterminal line [Goater]. Larva feeds on Sedge.
