A rather rare species throughout Belgium, more frequently observed in the sandy areas of the north of the country.
The larvae live in a tubular case covered with sand, on the stems and the roots of Ammophila, Corynephorus, Festuca ovina and probably other grasses. They hibernate. Pupation in a cocoon in sand at the base of the foodplant.
The adults fly in June and July. They are active at dusk and come to light.
