Betula pendula, Reusel
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 seamless. 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).
Alnus glutinosa; Betula nana, pendula; Carpinus betulus; Corylus avellana.
Larve are found from mid August; they are full grown end October. Pupation only after thibernation (Emmet, Langmaid, Bland ao, 1996a).
BE Recently rediscovered in Belgium in the province of Liège (ident. HW van der Wolf) (De Prins & Steeman, 2007); the case above represents a new observation.
NE recorded (Kuchlein & de Vos, 1999a); rare (Microlepidopter.nl, 2008).
LUX not recorded (Fauna Europaea, 2008).
