Europe
This is the common black ant of Europe. It nests variously in banks, under stones and in tree stumps along hedgerows and woodland borders. Workers are timid, fast moving and forage singly, predating small insects but also feeding on extra floral nectaries and on aphid honeydew. Colonies are usually small with up to 500 workers and one or a few queens present. Alatae are developed in June and July and fly off the nests in July and early August (Collingwood 1979).
