A fairly common species throughout Belgium, especially in the northern part.
The larva lives in a silken web in the seed-pods of their foodplant. Sometimes a single web contains more than one larva. The larvae hibernate in the web and pupate in spring. Pupation in a tough cocoon in the soil.
The adults are active at dusk and later come to light.
One generation a year from late April till the end of September with a peak in August.
