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. This patch is formed from old leaf material, incorporated into the first case (as shown).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.
