A very rare and local species in Belgium, mainly observed in the southern provinces.
The adults are active at dusk and later come to light.
The adults fly from mid June towards early August.
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.
