MD and Quicksilver,
I suspect you are correct. The thing that attacked me was big and fat while the things flying around the food are smaller and skinny.
So just so I'm understanding, the thing that stung me was a bee, but the things flying around the food are yellowjackets?
This is what the food guys look like (I think)
And surprisingly, they LOVE Smirnoff ICE. If you leave an open bottle of Smirnoff ICE out, within a few hours there will be 6-8 dead ones in the bottle.
I want to add, other than the flying thing that deliberately attacked my nose, it seems as though all the other bee stings have been, non-aggressive. It's not as if a swarm has attacked anyone. One of our friends got stung on the top of her toe and my wife got stung on her leg. Our other friend got stung by lying on the dead insect.
My point is, they don't seem "sting" aggressive, but they are food and pool aggressive.
