A rare species throughout Belgium, mostly found as a case. Most observations are from the western part of the country and in the Kempen, where it is sometimes not rare.
The fore wings are shiny ochreous grey, sometimes with darker stipples to the tip. The antennae are ringed alternately brown and white till 2/3 or more, sometimes even till the tip. The wingspan is 12–15 mm.
The larva makes a tubular leaf case. The case is almost barrel-shaped, with a large leaf fragment that, while withering, folds itself untidily around the tube. So giving the name "siccifolia" = dryed leave, to this species.

At first the lava makes little mines. After that the larva feeds from a tubular leaf case. The caterpillars are fully grown in Oktober.
Pupation in the case attached to a stem of the food plant, vegetation or tree trunks.
The adults fly in one generation a year: in May, June and July.
