General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
These ants walk around with their backside, or gaster, stuck up in the air. Very unique behaviour.
There's an interesting discussion on iNaturalist about this (and ant "hibernating" stategies) indicating the ants might be lifting their gaster off hot ground.
We will monitor ours to see if we can learn more. At this stage we don't believe it's heat related as their gaster is in the air both in full sun & in the shade (from memory)
