(Linnaeus, 1761)493 / 37.015

Morley’s Final Catalogue: An abundant and polyphagous kind. Copdock (Hkg); Bentley Woods in July, Gorleston and Fritton marshes (Mly); Campsey-ash ; Lowestoft.

Recent Status: A common species that is well recorded in Suffolk.

Life Style: The moth is single brooded night flying and comes to light flying in June and July. The larvae feed by mining leaves of Ulmus, Betula, Alnus, Corylus and Carpinus. They have also been reported, probably xenophagously feeding, on Sorbus, Malus, Salix cinerea and herbaceous plants. They hibernate and continue feeding in spring. They pupate in the larval case on a leaf or twig.

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 final larval case. C. serratella is by far the commoner species. 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.
The larvae of C. serratella initially form a gallery mine leading to a blotch which is excised for the first case. Subsequent cases vary in structure and are described in detail in the Moths and Butterflies of Great Britain and Ireland. More Info
