In Flanders confined to Limburg and in the south of Belgium mainly occurring in the limestone area. Populations are declining everywhere. Lower risk.
The adults fly usuallt in one generation a year; from early May towards late June. Occasionally a second generation occurs from early July till late August.
The larva lives on several species of Fabaceae, like Lotus corniculatus, Lotus uliginosus, Hippocrepis comosa. Hibernates as a larva in a sturdy cocoon made of spun leaves on the ground or on the food plant.
