Notes:
Nationally scarce (Nb) in hedgerows and scrubland throughout England. In Hampshire apparently restricted to the coastal strip east of Southampton, from Brownwich and Titchfield Haven to Hayling Island. Not recorded from the Isle of Wight to date. Wingspan 9-12 mm. Adults are indistinguishable externally from C. coracipennella and C. spinella and identification therefore relies on dissection of the genitalia. Larva mines leaves of Blackthorn and also Dwarf Cherry and Apple, living and feeding within a movable case; no feature is known for distinguishing cases of the three species, and the moths must therefore be bred and dissected.
