Formica rufa group
Ants of the Formica rufa group are large, aggressive, ecologically dominant ants in the northern hemisphere. Some European species are among the few ants with legal protection because of their importance in the control of forest insect pests.
Many rufa group species construct large thatch mounds (such as this one) and most are probably temporary social parasites of Formica fusca group ants during nest founding.
