A fairly common species throughout Belgium, more recorded in the northern part of our country.
The most common form, if not the only form in Belgium refers to the parthenogenetic form f. ferchaultella Stephens, 1850.
The larva lives in a conical small case covered with lichen and sand and feeds mainly on lichens growing on rocks, but also on wood, preferably in dry and sunny places. Hibernates as a larva in the case attached on rocks or trunks.
The moths emerge nocturnally and mate in the early morning. The female is apterous. The name f. ferchaultella Stephens, 1850 refers the parthenogenetic form. This form is the most common, if not the only form, in Belgium.
One generation a year: June–July.
Open areas, forest edges, humid habitats.
