The wingspan is about 13 millimetres (0.51 in). Adults are on wing in September and overwinter, reappearing in the spring.[2]

The larvae feed on alder (Alnus glutinosa). They mine the leaves of their host plant which consists of a small lower-surface blotch near the leaf margin. The mine is in fact a tentiform mine, but so little silk is produced that the blotch hardly contracts at all. The mine is preceded by a quite short corridor, that is overrun by the later blotch. Older larvae leave the mine and start feeding under a flap of the leaf margin that is folded down and attached to the blade underside with silk. Two or three such folds are made on the same or another leaf.[3]
