very local species in Belgium, only observed in the southern provinces.
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
adults fly in July and August. They are active at dusk and later
come to light.
