The Pepsis wasp http://tbn2.google.com/images?q=tbn:Z2hi鈥?/a> is by far the most painful sting by a winged insect rating a 4.0 on the The Schmidt Sting Pain Index where as a fire ant is only 1.2!!!! and a yellow jacket is only 2.0. The only insect above the pepsis wasp is the south american bullet ant (called so because it feels like a gun shot wound) at 4.0+.





Here is the full list:
