Sharks and crocodiles can snap up legs. The venom in a rattlesnake bite or scorpion sting will shut down a healthy heart in a matter of hours. But only one of nature’s killers sends my adrenal glands into overdrive. There, on the handle of my car door, with yellow and black stripes saying “Don’t mess with me,” it menacingly waits. It may have been a honeybee or a hornet or a wasp, but regardless, it was a member of superfamily Apoidea.
