Where the invasive ant Myrmica rubra (L.) has spread in southern New England, U.S.A., populations consist of multiple mutually aggressive colonies that compete for space. Colonies of M. rubra have not undergone the massive expansion in territory sizes observed in the invaded ranges of some other exotic ants. The degree of aggression between pairs of colonies did not vary consistently according to the distance of separation or whether colonies were neighbours.
