This is really living - and dying :o( - on the edge: two on one wrestling on the edge of a match!
If there's one thing I've learned from taking ant macros, it's that those large black ants and large brown ants don't enjoy each other's company! This is the only session where I put them together. The black one is the same type that bit my thumb, so I have a feeling that kind of ant might have a bit too much testosterone. The brown ones are called honey ants and they have an unusual smell.
In this shot, the ant on its back beneath the other one on the match head is a brown one and the other brown ant is pulling the leg of the black ant to try to stop it from attacking its brown friend. In the previous shot, the 'free' brown ant was hanging from the end of the match with the other two dangling via the black ant's leg, but that wasn't a very good shot at all, so I couldn't use it.
