Coleophora milvipennis explained

Coleophora milvipennis is a moth of the family Coleophoridae. It is found in all of Europe, east to Japan (Hokkaido).^[1]

The wingspan is 10–13 mm.^[2] Plain buff brown forewing with a pale costal streak. Only reliably identified by dissection and microscopic examination of the genitalia.

Adults are on wing in one generation per year from late June to July.^[3]

The larvae feed on Alnus glutinosa, Alnus incana, Alnus viridis, Betula nana, Betula pubescens, Carpinus betulus, Corylus avellana and Myrica gale. They create a spatulate leaf case. It is slender, bivalved and 8–11 mm long, with a slight curve at the rear end. The end is laterally compressed. The mouth angle is about 45°. The fleck mines are often conspicuously brown.^[4] Larvae can be found almost year-round.
