A common species throughout Belgium.
The larva lives on the seeds of the host plant. When full grown it enters the stem by gnawing a small hole in it. Overwinters and pupates in a cocoon in the stem.
The adults fly in the sunshine and often can be seen on the white flowers of different Umbelliferae or the yellow flowers of Rancunculus spp.
One generation a year: from mid May till mid June, most common in the second half of May.
Meadows, forest edges, road sides.
