A very local species in Belgium, only observed in the southern provinces.

The larva lives in a spun terminal shoot on Origanum, Mentha or Calamintha. It constructs a lare web intermixed with dead leaves of the foodplant. It hibernates and pupates in July of the next year in the earth or amongst leaf-litter in a tough, papery cocoon.

The adults fly in July and August. They are active at dusk and later come to light.
