A common species throughout Belgium.
Native
The larva lives in the roots and it hibernates full-fed in a silken cocoon in the feeding places or in the soil. Pupation takes place in May in the cocoon.
The adults can easily be disturbed during the day but
are active at dusk and later come to light.
The adults usually fly from mid-May till late September in one long annual generation.
The larva lives on Carduus species, occasionally also on Cirsium.
Found in many habitats including grassland, fens, open woodland, heathland, waste places and gardens, where the foodplant occurs.
