Known from old records in NA and LX. Now extinct, but there are some small populations not so far from the Belgian border!
Last observation in 1971 at Dourbes (NA).
Native
The larva is attended by ants of the genera Lasius and Myrmica. The species hibernates as a larva or as a pupa.
The adults fly usually in two generations a year onwards from April towards June and again from late July to early September.
