Food Plant: Alnus glutinosa (Alder), A.incana (Grey Alder)

Mine: June-September

Notes: The mine formed in the leaf-veins and midrib leads to an oval blotch, then a cut-out in leaf-blade. The initial mine is shown - the larva re-enters then leaf midrib and mines back, almost to the petiole. It will alter re-enter the leaf to form the cut out.
