FIG. 6 in Foraging ecology of the giant Amazonian ant Dinoponera gigantea (Hymenoptera, Formicidae, Ponerinae): activity schedule, diet and spatial foraging patterns

FIG. 6. Ritualized territorial contest between Dinoponera gigantea foragers from diVerent colonies at the border of their foraging areas. (A) Ants lock their mandibles together, vigorously antennate each other's head, and constantly kick one another with the Žrst pair of legs. (B) As the contest escalates the dominant ant (right) directs the tip of the gaster against the opponent's body. The subordinate ant eventually walks away as she breaks free.
