I got stung by a yellowjacket on my face once while riding my motorcycle. It flew up over the windshield and under the visor of my helmet at about 60 mph and stung me just under the eye before it died. It hurt like hell, and when I was able to stop in about a mile my wife and friend wondered why I stopped in a bad spot until I took off the helmet. I used a sting stick on it and the bite went down after a while, but it left a welt for a while too.
