The wingspan is 21–25 mm. Very similar to forms of Acleris hastiana but the forewing has more pronounced scale-tufts. Certain identification requires genitalia dissection. Julius von Kennel gives a full description.[4]

Adults are on wing in one generation from August to late October and, after hibernation, from mid-March to May.[5]

The larvae feed on Abies alba, Pinus and Picea species (including Picea excelsa and Picea abies). They live in a loose spinning between the needles of their host plant. Larvae can be found from June to July.
