Pat - thanks for the updated location - this doesn't look like the usual coconut ant which has a dark single tone abdomen. Did it have the coconut ant smell - the grass/carton construction or sapling "base camps"?
Hi Pat & Michael. I can't really see the ant well enough to ID it positively. The light and dark bands on the abdomen are caused when the ant has sucked up a lot of honeydew, and the abdomen swells up like a balloon, exposing the thinner, more lightly coloured sections of each of the plates which makes up the abdomen. So it could be Papyrius, but the smell test would be important to confirm the ID. Cheers, Jon
They definitely had the grass carton construction and smelled like coconut when squashed. I had photographs of the nests but there was some kind of issue when uploading the images
