Thanks Jon. Do you know what area a colony of coconut ants might occupy- 10, 50, 100 metres wide? I imagine this sapling is a foraging site for a nest in a stump a few metres away, but there are many nests across the track.
Hi Mike, I have measured the area of the colony of Papyrius near the Namadgi visitor centre (the larger, hairy undescribed species) and it was around 60m long and 10 - 20 m wide, with GPS sampling points giving minimum polygon area of about 460 sqr m. Other sites are fairly commonly around 200 sqr m. So, yes, it is certainly possible that any sightings within 10 or 20 m are all the same colony. Cheers, Jon
