Only known from a single record: Belgium, NA, Rochefort, 1849, 1 specimen, leg. J. Colbeau. Probably extinct now.
Ground colour either brownish or greyish white, both forms without a real pattern but with a lot of darker scales all over the wing giving a mottled appearance. There exist also many mixed forms.
A greyish green, transparant cocoon on the underside of a leaf.
Free living instars at first feed under a folded leaf margin and then roll a leaf tip downwards. The caterpillars make two such rolls. They have a preference for fresh leaves. The species hibernates in the adult stage.
Two generations per year: May–June and July–August.
