A very rare species, mainly known from some very old records in the southern part of the country, especially in calcareous grassland in the extreme south of LX. A healthy population exist not far from the Belgian border in France.
Recently (2019) an observation became known from LX after a long period of absence. Further research shows that small populations survive here in southern LX.
