Executioner wasps are a species of social wasp found in Central and South America, mostly being spotted in Mexico, Paraguay, Argentina, and Brazil. Though they’re not commonly found in the United States, they are sometimes discovered in Texas.

Nicknamed the King of Sting, the executioner wasp is considered the most venomous wasp in the world with the most painful sting of them all. The pain encountered once stung is due to the histamine (inflammation, dilates blood vessels, affects muscle contractions) and norepinephrines (increases heart rate) properties in their venom that break down living cells and tissues around the sting site. It has a near unparalleled burning and throbbing sensation that can leave the effected area swollen and painful for days following the initial sting. Chances are, you would be okay if you got stung. But, if you’re allergic to insect stings, or if you’re a child or elderly individual, this would be one of the very worst insects to get stung by and it could certainly lead to your death.

Executioner wasps mainly feed on caterpillars before they turn into moths and butterflies. This gnarly insect often times decapitates its prey, much like that of a praying mantis.

They have an impressive longevity to them, generally living between 6-and-18 months, which is just astounding when considering the lifespan of other insects.
