Recorded only once from Belgium during an excursion to Kalmthout (AN) on 05.viii.1861, leg. E. Fologne, L. Mors & J. Weyers, where they found this species "very common on an arid sand dune without any vegetation, running more than flying".
Nowadays probably extinct in our country.
Wingspan 9 mm.
The larva spins a long, tubular gallery of silk, mixed with sand, extending beneath the sand. Its development is very slow. It can be found in April–May.
Pupation in June in a long, curved cocoon just below the sand surface.
Adults do not fly often, when disturbed they prefer to run or jump. They can hardly be seen because they rest on the food plant and resemble very much a leaf of heather.
One generation a year: June–July.
Heathland on xerothermic sandy soils.
