A rare and local species in Belgium, but probably overlooked in many regions. Recent observations only from the northern part of the country.

The larva mines at first in the flowering stems and umbels of various species of Oenanthe and Carum verticillatum and occasionally on Sison amonum. In a later stage, the larva feeds within a tough silken spinning externally among flowers and developping seeds. Pupates 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.

The adults fly in one generation a year; from August till September and after hibernation again from March towards April. They fly by night and later come to light.
