A local species occuring only in the south of Belgium. Seems to be recovering from a period when only one small population survived in the southernmost tip of Belgium, now it can however be seen again in several calcareous locations in NA and LX.
The adults fly in two generations a year: from mid May till June, and from end of July till end September.
The larva lives on Hippocrepis comosa and Coronilla varia. The larva is attended by different species of ants and hibernates. Pupation usually under a rock or litter near the entrance of an antsnest.
