(Hymenoptera: Formicidae) Myrmica ants attacking queen horse ant Camponotus herculeanum, Torsby, Värmland (Sweden). The horse ant queen was unlucky and got caught by a small red ant and others joined to make the kill. The queen may also have been run over by a car and then the ants are scavanging. Either hypothesis is farily likely as the queen was found in the road.
