I got stung by a bee while riding about a month ago. I open my helmet as I reach a stop, ride for about 1/2 mile with it open and I see something, then feel a lot of pain. It was probably a hornet because I don't think they leave stingers behind, but it hurt alot. Got me about 1/2" from my eye; luckily I have to wear glasses.
The only difference is I did have a little swelling, but a nice red mark and the pain lasted for less than a day.
