Podomyrma adelaidae is found throughout temperate Australia and is easily recognised by the pair of white spots on the gaster. Workers can be seen foraging on the trunks of eucalypts, particularly smooth- barked eucalypts.

  • P. adelaidae workers engaging in an apparent territorial dispute. Usually when workers from different colonies intrude on each other's territory, they will antennate or engage in ritualised fighting to resolve the dispute. But when this fails they will attack one another. A dominance battle ensues, with the victor retaining rights to forage in the area. In this case one worker has a strong grip on the other's antennae and showed no signs of releasing it while being photographed.
  • Part of the same territorial battle, this pair of workers were engaged in a struggle nearby. The smaller worker kept trying to escape but the larger worker had a firm grasp of its postpetiole.
  • Podomyrma adelaidae tends to a Lycaenid caterpillar. These caterpillars secrete substances that the ants find attractive, and the ants in turn provide protection from parasites. Poochera, South Australia. © Alex Wild.
