The first observation for this species in Belgium was on 11 October 2007 in NA. Hitherto still a very rare and local species.
The forewings are yellowish brown with dark stipples at the tip of the wings. There is a whitish costa line. Wingspan is 9–10 mm. The antennae are alternately ringed brown and white till the tip.
The case is reddish brown, tubular and made of silk. It is 5–6 mm. This case is strongly constricted just behind the mouth, and weakly near the anal end. The mouth angle is 0°. Therefore the case lays flat on the leave. The fully developed case normally is trivalved.

Larvae live at the underside of the leaf, perhaps in springtime more often on the buds. Fully developed cases in late April, early May.
The adults fly from late May till the beginning of July.
The larva lives on Rosaceae like: Amelanchier, Crataegus, Cotoneaster, Malus, Prunus and Sorbus. Especially Crataegus and also Sorbus are the most taken plants in Belgium.
