Coleophora fuscocuprella  Herrich-Schäffer, 1855

A rare species in Belgium.

The larva lives in a greyish brown lobe case on Betula, Carpinus and Corylus and mines from the underside, peppering the leaf with numerous small blotches. The rear end of the case is strongly bent, almost pointing back towards the mouth angle, which is being set between 60 and 80° to the long axis. Pupation in the case, usually attached to a trunk just above ground level.

The adults fly in one generation a year occuring from mid May towards late June. They come infrequently to light.
