Solitary wasps like the eastern cicada killer are very different in their behavior from the social wasps such as hornets, yellowjackets, or paper wasps. Cicada killer females use their stings to paralyze their prey (cicadas) rather than to defend their nests; unlike most social wasps and bees, they do not attempt to sting unless handled roughly.
Hornet stings are more painful to humans than typical wasp stings because hornet venom contains a large amount (5%) of acetylcholine. [ 8 ] [ 9 ] Individual hornets can sting repeatedly. Unlike honey bees , hornets do not die after stinging because their stingers are very finely barbed (only visible under high magnification) and can easily be ...
The toxicity of the venom of the Maricopa harvester ant is well known. Its LD 50 value is 0.12 mg/kg (injected intravenously in mice); 12 stings can kill a 2-kg rat. In comparison, the LD 50 of the honey bee is 2.8 mg/kg—less than one-twentieth as strong. In humans, a Pogonomyrmex sting produces intense pain that can last up to four hours. [3 ...

The description of barbed or unbarbed is not precise: there are barbs on the stings of yellowjacket wasps and the Mexican honey wasp, but the barbs are so small that the wasp can sometimes withdraw its sting apparatus from ...
