Biology. This is one of the commonest European species and is often especially evident at sites of human disturbance including towns, villages and quarries. Nests may occur in walls, pavements, tree stumps in open woodland, pasture and open heath. Occasionally earth mounts are formed and foraging tracks are frequently covered by surface tunnels of earth. This species is aggressive and readily attacks other ants. Nests are single queened and moderately populous with several hundred up to 10,000 workers. Aphids on shrubs and herbs as well as subterranean species are tended. Mating swarms occur from July to late August and in some years huge numbers may fly over a large district on the same date.
