These two beetles have some sort of heavy beef that they needed to take care of.

I'm not quite sure why these two bugs throwing haymakers at one another looks like it could be a legitimate MMA fight, but it really does.

There's definitely some hard punches thrown. There's some grappling happening in there. And even after one beetle runs off, signaling the winner who stays in the middle, the winner has a raging celebration all by himself...very much like an MMA fight!

Also, apparently humans videoing bug fights is a major thing.
