Europe
(Native Range), Collingwood (1979) - This is a lowland species often abundant where it occurs in sheltered valleys, usually in alluvial soil by riversides and on the coast. Colonies are normally polygynous with several to many queens and up to 1000 or more workers (Elmes, 1973b) nesting in the ground or under stones. Microgynes are quite frequent with this species (Collingwood, 1958; Elmes, 1973a). This is the most aggressive of the Myrmica species and stings freely. This ant tends aphids more consistently than other members of the genus and is frequently found collecting nectar on the inflorescence of umbelliflorae and other herbs. Mating flights occur in August and are orientated towards high buildings.
