(Coleophora fuscocuprella)
Coleophora fuscocuprella is a moth of the family Coleophoridae. It is found from Fennoscandia to the Pyrenees, Italy, Albania and Romania and from Ireland to Russia. The wingspan is 8–10 mm. Head shining dark bronzy-fuscous. Antennae dark fuscous, apical half white with dark fuscous rings, indistinct towards apex. Forewings dark bronzy-fuscous. Hindwings dark grey. There is one generation per year with adults on wing from mid-May to late June. The larvae feed on Alnus, Betula pendula, Betula pubescens, Carpinus betulus and Corylus avellana. They create a lobe case with many small leaf fragments attached to it. The larvae are attached to the leaf underside, where they make a large number of relatively small fleck mines. Full-grown cases can be found in August and October. Pupation takes place in the case, usually attached to a trunk just above ground level.
