Morley’s Final Catalogue: Copdock (Hkg); Ipswich in 1904 (Mly) and bred freely from larvae on Bentley Woods' oaks in 1934 (Trans, u, p. clxxvi); Brandon (Barrett).
Recent Status: This common species is recorded in Suffolk.
Life Style: A single brooded species that flies at night and comes to light. It can be found during June and July. The larvae mine Quercus leaves and catkins from a mobile case. They hibernate and feed again in the spring before pupation.
Identification: Three species C. lutipennella, C. gryphipennella and C. flavipennella are very similar as the adult moth and can only be reliably identified by dissection of the genitalia. They sit with their wings fairly flat at rest and are a buff, ochre or pale ferruginous colour. More Info The larvae of C. lutipennella and C. flavipennella are very similar and both feed on Quercus. The first case of C. lutipennella is of silk and that of C. flavipennella is constructed from leaf cuticle. C. lutipennella may also feed on Quercus catkins during spring as well as mining leaves. They are otherwise the same. More Info
