Food Plant: Quercus spp. (Oaks)

Mine: Late September to late October, then April to late May

Notes: First case formed of silk, including a small leaf fragment, larva mining leaves. The winter case is shown - to the naked eye it appears to have a pale patch on the anal end. The winter case of C. lutipennella does not have this patch. Feeding in spring in a new case on catkins and also mining leaves. Very similar to case of C. lutipennella. The larva is orange-brown (as shown) with a large prothoracic plate with a fine median sulcus.
