case

Composite leaf case. The material used to enlarge the case consists of large pieces of fleck mine, that are attached with such precision that they may seem seemless. In the course of summer an autumn two (sometimes three, according to Hering, 1927b) pieces are added. No more material is added after hibernation, causing the case in spring to be rather uniformly coloured (contrary to C. binderella, that does add an extension in spring, made of fresh leaf material).

host plants

Betulaceae, oligophagous

Alnus glutinosa; Betula nana, pendula; Carpinus betulus; Corylus avellana.
