Coleophora ibipennella Zeller, 1849

forest case-bearer

case

The full grown larva in a black pistol case of 7 mm long. The mouth angle is c. 80°. From the rear end a grey silken cloak (“pallium”) hangs down to almost halfway the mouth.

hostplants

Fagaceae, monophagous (?)

Quercus pubescens, robur.

Hering (1957a) and others write that the species may also live, albeit rarely, on Betula; this is doubted by Emmet ao (1996a). Zoerner (1971a) found cases on seedlings of Fagus sylvatica; Drăghia (1972a) mentions Pyrus as a host. Probably these cases refer to stray larvae, trying to find a hibernation spot.

phenology

Larvae are full grown in early June (Emmet ao, 1996a).
