Vulnerable (proposed as a future Red Data Book species) in hedgerows and scrubland in parts of south-eastern England. In Hampshire recorded for the first time at Farlington Marsh in 1988, and on the Isle of Wight on 18 September 1977, with few records anywhere since. Wingspan 9-10 mm. Adults are very similar externally to C. badiipennella and C. trigeminella and identification therefore relies on breeding through from mines, or by dissection of the genitalia. Larva mines leaves of Blackthorn, living and feeding within a movable case; case length 6-7 mm.
