A very rare and local species in Belgium.
The adults are easy to disturb during the day out of vegetation. They are active at dusk and later come to light in small numbers.
The adults have been observed from May till early August and fly in two generations a year.
The larva lives in the roots of Hieracium umbellatum, Sonchus and Vaccinium.
Xerotherm places with slate stone.
