Morley’s Final Catalogue: Bred plentifully from larval cases beaten from hawthorn at both Bentley Woods and Monks Soham in 1931 (Mly); bred at Ipswich (Whit.); Southwold (Ctw), Blythbro Wood; Tuddenham (Wrn).
Recent Status: The species is recorded in Suffolk.
Life Style: A single brooded species that can be found in June, July and August. The larvae mine the leaves of Prunus and also Malus and Crataegus. They hibernate when young and pupate on the foodplant.
Identification: There are four similar species C. coracipennella, C. serratella, C. spinella and C. prunifoliae that cannot be separated on the superficial characters of either the adult moth or the larval case. To some degree C. serratella can be separated out on its usual foodplant but it is not exclusive to such without sometimes being found on Malus. All adults are dark, grey or fuscous with a lighter fine peppering. C. serratella also has a paler form apparently when it has fed on Ulmus. All have sharply annulate antennae. Adult moths can be identified by genitalia dissection. More Info
