Stings are usually located at the rear of the animal. Animals with stings include bees, wasps (including hornets), some ants like fire ants, and scorpions, [2] [3] as well as a single beetle species (Onychocerus albitarsis) that can deliver a venomous sting from its antennae, whose terminal segments have evolved to resemble a scorpion's tail.

Yellowjackets have lance-like stingers with small barbs, and typically sting repeatedly, [1] though occasionally a stinger becomes lodged and pulls free of the wasp's body; the venom, like most bee and wasp venoms, is primarily dangerous to only those humans who are allergic or are stung many times. All species have yellow or white on their faces.
A European hornet stinger under an optical microscope. Hornets have stingers used to kill prey and defend nests. 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.
Yellowjackets and paper wasps are the two most common social wasp species in Northern California, Kimsey said. Social wasp colonies are started from scratch each spring by a queen who survives ...
Typically, paper wasps are relatively unaggressive, only attacking humans and animals if they or their nests are being threatened. As in other aculeate wasps, only females have the ability to sting. [16] Unlike bees, wasps do not have barbed stingers that can be lost, so they are able to sting multiple times to defend a nest. [17]

The 2-inch-long hornet, with a stinger longer than that of a typical wasp, can deliver potent venom, but is largely dangerous to bees and other insects, not humans. Eradication efforts started ...
Once prey has been found, a female wasp will typically attack a target beetle by alighting on it, climbing over it, and grabbing it by the thorax with her mandibles before inserting her stinger into the base of the beetle's leg (in the membrane of the coxal joint, a gap in the buprestid's armour) and injecting a paralytic venom.
