I have seen these little ant/wasp insects before, but I can't remember if I ever put a name on them...
I think they are a kind of ant, but I'm not totally positive...
New species for me, too bad I wasn't in a great position to photograph it. I would have put the box on it if I could.
ID based on discussion with a few people, and it favourably matches online images too.
