These are also referred to as Ambush Bugs and they earn this name because of their habit of hiding and preying on those who don’t notice them. They kill their prey with a sharp beak that injects venom and they can give a pretty nasty sting with it, too. This venom liquifies the insides of the prey so they can be sucked out. These are not well known insects although they can be found across the US. They have wings and do fly and on occasion are caught in spider webs; they will the bite spiders and the venom will kill them. If the bite to the spider is in their leg, they can release that leg and save their lives. Most of these bugs are harmless to humans but there are a few that an inflict a painful bite. There are around 7,000 species of this family.
