A scarce species in Belgium. It used to be more rare in the north of the country but it has increased since the 2010's and can now be observed all over the country again. It is still more commonly observed in the southern part however.
The species hibernates in the adult stage. The imagos can wake up during warm, sunny weather already from mid-February.
The adults fly from the end of June till early May of the next year.
