A not so common species in Belgium, probably overlooked.

The monophagous larvae feed on Alnus glutinosa. Initially mining the underside of the leaf and then creating two or three successively folds on the margin of the leaf, which closely resemble those of a Parornix species. It hibernates as an imago.

The adults fly in one generation a year; emerging during September, overwintering and then flying until May. The moths are very elusive and not often seen.
