Recent Status: There are records of this species for Suffolk. The species is reported to be commoner than C. serratella in southern England.
Life Style: A single brooded species flying in June and July. The larvae mine leaves of Crataegus, Malus, Pyrus, Prunus, Sorbus and Cotoneaster. They hibernate in their first instar. They 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
