Can confirm, ants in Australia are evil.

Though I haven't done research on this topic, I do have a first hand account of how freaky red bull ants are.

I've gone hiking and sometimes I come across them. I usually hike with poles, so I always look before I plant. I planted by a red bill ant once, and it really took offense. It kept facing me no matter which direction I was from it, like it was waiting for an opening to climb my shoe, sock, and get my leg. I have been "stalked" when taking small steps away.

I don't think they sting, but their mandibles, though. 💀 Not sure if there's any documented deaths caused by this ant, but it sure would hurt being bit. Same with bull ants. Deaths from anaphylaxis probably, though.
