Coleophora bilineatella

Description

Coleophora bilineatella is a moth of the family Coleophoridae. It was described by Zeller in 1849. It is found from Germany to the Iberian Peninsula, Sardinia, Italy and Greece and from France to Romania. The larvae feed on Dorycnium pentaphyllum, Dorycnium pentaphyllum germanicum and Dorycnium pentaphyllum herbaceum. The youth case is 2–3 millimetres (0.079–0.118 in) long, laterally compressed, composed of the epidermis, distally narrowed and curved. Later, they create a very slender composite leaf case of 12–19 millimetres (0.47–0.75 in) length, composed of 7-9 leaf fragments. The mouth angle is about 45°. Full-grown larvae can be found from June to April. Hibernation occurs at the foot of the hostplant.
