I took a stroll downtown at noon to see the sights and grab some lunch. Along the way, I ran across a raised flower bed positively teeming with large, angry-looking wasps. Leah and I had seen one of these bugs flying around the front stoop at home the other day, and it sure looked menacing. Like, if you got stung by one of these suckers, it’d hurt 10X worse than being stung by a regular wasp.
As luck would have it, I bumped into a colleague shortly after passing the wasps who told me they’re colloquially called cicada killers. Google and Wikipedia came to the rescue, as they have so many times.
While they may be frightfully large,[1] female Cicada killer wasps are not aggressive and rarely sting unless they are grasped roughly, stepped upon with bare feet, or caught in clothing, etc. Males aggressively defend their perching areas on nesting sites against rival males but they have no sting. Although they appear to attack anything which moves near their territories, male cicada killers are actually investigating anything which might be a female cicada killer ready to mate. Such close inspection appears to many people to be an attack, but the wasps rarely even land on people. If handled roughly females will sting, and males will jab with a sharp spine on the tip of their abdomen. Both sexes appear to be well equipped to bite, as they have large jaws; however, they are unable to grasp human skin and cannot bite. They are non-aggressive towards humans and fly away when swatted at, instead of attacking. Cicada killers exert a natural control on cicada populations and thus may directly benefit the deciduous trees upon which cicadas feed.
