A fairly common immigrant throughout Belgium, which can establish itself temporarily for a certain period. Numbers can vary from year to year.
The adults have mainly been observed in June and July. They fly at dusk and later come to light.
The larva feed on the flowers and the seeds of Daucus, Pastinaca, Heracleum sphondylium or Foeniculum. It spins the flowers together and hibernates, sometimes two years, in that spinning. Pupation takes place in a tough silken cocoon in the earth.
