not a "wasp", but kinda close.
it is two species of bees though....
sorry i didn't have a better camera, i layed on our hammock, then felt something fall on my leg and it was these two bees fighting... well, one actually trying to kill the other, the other trying to get away.
the bigger one was behind the smaller one, with mandibles on the others waist, trying to cut the smaller one in half, like they do to honey bees. that should be a hint, if you know these bees.
