They are big, have long legs, and move fast.
M. bagoti is one of the most heat tolerant ant in the world. It is active in the heat of the day. Behaviour is one component of foraging in the heat. When the ground gets really hot, the ant spends more and more time climbing onto plants to escape the heat.
Some of these ants have been painted for identification. The winged ones are queens.
Ants at the CSIRO
After working at Simpson's Gap, we then rented the house at what was then the CSIRO Centre for Arid Zone Research, and found the ants roaming around the grounds. The CSIRO site became our new field site. It is still cluttered with grass tussocks, bushes, and trees.

In the 2008-2009 season, we witnessed a large number of queens and males emerging, as well as some queens establishing (or trying to) nests on our field site. We got some good shots.
