Distribution. Present in Scandinavia only on the islands of Gotland and Gland. It occurs on sandy heaths and along the coast in South England and in the Channel Isles. - Range: throughout Central Europe from Spain to the Caucasus and from the mountains of South Italy to North Germany.

Biology. This is a small black ant, agile and aggressive on disturbance. Colonies usually contain several hundred workers and many queens. Nests are constructed under stones or in bare ground in dry sunny places and loose earth solaria for brood incubation are often constructed during the early summer. This species is partly aphidicolous and partly carnivorous. Alatae are developed in June with flights occurring during July.
