A fairly common species throughout Belgium.
Native
The larva lives in the seeds and sometimes burrowing into the stem on the host plant. It overwinters in a cocoon in the soil and pupation takes place inside that cocoon.
They fly from late evening and later come to light.
The adults fly from late May till late August, occasionally later. Most observations during July.
It has a preference for dry places like pasture land, uncultivated ground, gravel pits, chalk downland etc...
