Modlmeier hat in seinen Versuchen einzelne Ameisen mit toten Artgenossen zusammengebracht und beobachtet, wie häufig es zu aggressiven Interaktionen kommt.
Dazu zählte er die Öffnung der Mandibeln, was eine Drohgebärde darstellt, Beißen, Zerren oder Stechen.
Von 39 verschiedenen Kolonien wurden jeweils 10 Arbeiterinnen ausgesucht und anhand ihrer Größe, ihrer Aggressivität und ihres Explorationsverhaltens charakterisiert.

He registered actions such as the opening of the mandibles (threat display), biting, pulling, and stinging.
Ten worker ants were selected from each of 39 different colonies to be classified by their size, level of aggression, and exploratory behavior.
