Used to be a rather common species throughout Belgium, but nowadays rather rare. Can be locally fairly common especially on sandy soils. Adults are very variable according to habitat.
The larva feeds mainly at night.
The adults fly from late June till the beginning of September in one generation a year.
The larva feeds on roots of the host plant. Hibernates as an egg. The adults come to light and sugar.
