I've been stung by Rhytidoponera so many times already... what's once more?
Also they are one of the ants that made me hate ants for many years because when I moved from NSW to QLD I sat down on grass in School for remembrance day and there happen to be a huge nest of them there. I got stung and bitten all up my leg. I was paranoid for many years after that about big black ants. I was told they were called Green ants (Their nickname) but they always looked black to me. Only until a month ago have I had a closer look at them in the sun and seen they shiny really nice green. xD
There are colonies of them around here everywhere. Its like they had a boom in population as soon as I started to keep ants and started to see ants in a new light. I'm still not going near them tho hahaha
Wait I wrote out a whole reply thinking you were talking about green tree ants/weaver ants/Oecophylla-
I only realised that you meant Rhytidoponera when you said they were in the ground oof
I am yet to be stung by Rhytidoponera but I'm sure it will happen soon, having a few queens.
Rhytidoponera stings are easy to avoid imo since they can't climb and aren't the quickest ants.
