A rare species in Belgium, mainly distributed in the northern part of the country.
The larvae from the spring generation, living in the upper part of the stem immediately below the flowerhead, eating the developing seeds of the host plant. Those of the second generation have been found on the shoots, feeding on the pith of the stems. Pupation in a silken cocoon in the earth or in debris.
The moths fly actively above the foodplants from dusk onwards, and later come to light.
The adults fly in two generations: end of May to early July, and again from August to September.
The larva lives on Scabiosa and on Centaurea nigra.
