Coleophora argenteonivea Walsingham, 1907
Before the hibernation the larva makes two or three cases consisting of a single leaf fragment; after the winter a composite leaf case is made. The latter consists of 3 – 4 leaf fragments; the case is brown, c. 15 mm long, bivalved, and has a mouth angle of c. 45°; dorsally and ventrally the case bears a strong but irregular keel.
Probably on more species of these or related genera.
