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 ...
European hornets have been observed to steal prey from spiders, which can be classified as an example of kleptoparasitism. This behavior was first documented in 2011 against a yellow garden spider, Argiope aurantia. A European hornet flew into the spider’s web and appeared entangled.
The hornets can devastate a colony of honey bees, especially if it is the introduced western honey bee. A single hornet can kill as many as 40 bees per minute due to its large mandibles, which can quickly strike and decapitate prey. [91] The honey bees' stings are ineffective because the hornets are five times their size and heavily armored.
Insect sting allergy is the term commonly given to the allergic response of an animal in response to the bite or sting of an insect. [1] Typically, insects which generate allergic responses are either stinging insects ( wasps , bees , hornets and ants [ 2 ] ) or biting insects ( mosquitoes , ticks ).
Vespa tropica, the greater banded hornet, is a tropical species of hornet found in Southern Asia, New Guinea and west Africa, and which has recently been discovered to be an invasive species on the Pacific island of Guam. It is a predator of paper wasps and possesses a potent sting, which can cause extreme pain and swelling.
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.

Many arthropods bite or sting in order to immobilize their prey or deter potential predators as a defense mechanism. Stings containing venom are more likely to be painful. Less frequently, venomous spider bites are also associated with morbidity and mortality in humans. Most arthropod stings involve Hymenoptera (ants, wasps, and bees). While ...
