A rare species in Belgium.
The larva feeds first in epidermis and later inside the roots. Larvae of the summer generation feed in twigs. Pupation outside the feeding place. The adults can sometimes be found at rest on the food plant and later come to light.
The adults fly in two generations a year; during May and June and again onwards from mid July to late August.
The larva feeds on Senecio jacobaea.
