Not sure if this site has already been posted. I will post three separate sightings, though all quite close together, different vegetation is involved, and the ants even looked different. At this spot I did the small test, but not the other two spots.
Thanks Christine this is an old woodland Travelling Stock Reserve and quite close to the hill-top that was the only known location of the small ant-blue butterfly before you came on the scene - so this is probably a spot to keep an eye on.
