Bluish grey, with many conspicuous white-ringed raised black spinacula on all segments; head capsule black, prothoracic plate dark brown, last abdominal segment ochreous to dark brown.


The eggs are oviposited singly.
The larva mines at first in the flowering stems and umbels of their host plant. In a later stage, the larva feeds within a tough silken spinning externally among flowers and developping seeds. Larval stage from the end of May till early August.
Pupation in a flimsy silken cocoon in a hole in the main stem of the food plant. If the potential pupation side is too small in diameter, it pupates in the soil or among plant debris on the ground. Pupal stage in July–August.
The species hibernates in the adult stage. Adults are active at night and come to light.
