This very rare and declining species is only known from a few places in the southern provinces in Belgium.
Hibernates as larva and pupates in a cocoon near the ground. They are active during the day and both sexes visiting flowers. They have a slow flight.
The adults fly from late May towards end of July.
The larva lives on Helianthemum nummularium.
