A common species throughout Belgium, especially in the northern part.
The adults fly from the beginning of June till the end of August. They are active from late afternoon and come to light.
The larvae live in the flower heads of Cirsium vulgare, Carduus spp. or Centaurea nigra. They hibernate in a cocoon spun amongst leaf-litter or in the soil and pupate in this cocoon.
