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 ...
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.
European hornets benefit from legal protection in some countries, notably Germany, where killing a European hornet or nest has been illegal since January 1, 1987, with a fine up to €50,000. [25] However, the highest reported fine levied in Germany for killing of wasps was €45, and experts report that fines are rarely imposed.

The Asian giant hornet (Vespa mandarinia) or northern giant hornet, [2] [3] including the color form referred to as the Japanese giant hornet, [4] [5] is the world's largest hornet. It is native to temperate and tropical East Asia , South Asia , Mainland Southeast Asia , and parts of the Russian Far East .
The "spray sting type", the term given to the venom-ejecting mechanism of these wasps, involves the contraction of the venom reservoir muscles. [4] This venom spraying mechanism allows for a greater release of alarm pheromone in the venom, which is key to elicit the attack behavior of yellowjackets.
