This is an inconspicuous species of slow movement, mainly carnivorous, living in small nests with two or three queens and 12 to 35 workers. Nests are found under stones or moss in broken stony ground, banks or crumbling cliffs and among flints in open woodland. Alates occur during August and September and have been caught by sweeping hedgerows in late summer. Published as part of Collingwood, C.
