A fairly common species throughout Belgium, especially in the northern part.
The adults have been observed from the beginning of May till the end of August. They are active in early evening and later come to light.
The larva feeds September till May in spun flowers or seed-heads of Achillea millefolium, Centaurea spp. or Anthemis arvensis. It hibernates in the larval feeding place. Pupation in a silken cocoon amongst detritus.
