Abstract Die Libelle Anax junius legt Eier im Tandem ab. Die Eier werden in Pflanzen eingebohrt. Fremde Männchen greifen die Tandems an und versuchen diese zu trennen. Die Attacken können so heftig sein, daß die erschöpften Tiere ins Wasser fallen und ertrinken.
The dragon fly Green Dander lays egg "in tandem" in pond areas rich in vegetation. Single males approach pairs in tandem and attack them. The male in the tandem defends itself from its attackers by beating its wings, clinging to plants and shaking them off. Attacks can be so violent that the animals fall in the water and drown.
