Recent Status: A common species probably under-recorded in Suffolk owing to identification constraints.
Life Style: A single brooded night flying species that comes to light. It can be found in June and July. The larvae mine leaves of Quercus. They hibernate and continue feeding in spring until pupation on the foodplant.
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. C. flavipennella may have a paler basal streak on the costa but this is not normally sufficient to allow identification. It is less pronounced than in the C. milvipennis group. 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. They are otherwise the same. C. gryphipennella larvae feed on Rosa and has a case differing in appearance to the others. More Info
