A rather common species in Belgium, especially in the south. It is rarely observed in the northern parts.
The bionomics are described elaborately on the Butterflies in the Benelux website.
The adults fly in two generation a year: from early May till mid June, and from early July till the end of August.
The larva lives on Lathyrus and Lotus.
