This is a video made by someone who obviously admires the "Schmidt Pain Index," which rates the stings of insects on a scale of 1-4. Justin O. Schmidt, an ESA emeritus member at the Southwestern Biological Institute in Tucson, Arizona, created the index. This video shows the amount of pain caused by different insect stings. NOTE: It has been pointed out that there are a few misidentifications of insects in this video, but Dr. Schmidt wrote, "I noted the small errors, but overall thought it was a nice job."
