Widespread in Bulgaria, especially frequent on calcareous terrain.
Unimproved grassland. Occurs in appreciably longer herbaceaous vegetation than in the UK and northern Europe, as the warmer climate means that the microclimate is warmer in taller vegetation, presumably providing suitable conditions for the host ants.
Recorded in 43 (2.3%) of the 1900 10km squares of Bulgaria.
