not so common species in Belgium, probably overlooked.
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.
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.
