Paraponera is a genus of ant consisting of a single species, the so-calle bullet ant (P. clavata), named on account of its powerful and potent sting, which is said to be as painful as being shot with a bullet. It is called by the locals, "Hormiga Veinticuatro," or "24-hour ant", from 24 hours of pain that follow a stinging. The bullet ant inhabits humid lowland rainforests from Nicaragua south to Paraguay. Workers are 18-25 mm long and look like stout, reddish-black, wingless wasps.
