A common throughout Belgium.
The adults have been observed from late May till late September. The males fly by day active in sunshine. Both sexes are active from dusk onwards and come to light.
The larva lives first on the surface of the roots and later inside the roots of Taraxacum. The larva hibernates. It pupates in a cocoon in or near the roots.
