The biggest species of wasps in the world is found in China. Their stings can lead to respiratory distress. If the person who has been stung survives, kidney failure may set in. Moreover, this wasp’s venom contains acetylcholine. This is a neurotransmitter that stimulates the nerve fiber, which increases the level of pain. (These wasps are definitely sadistic!)
Note: Speaking of the Mandarinia de Vespa, which is the scientific name for the wasp in question, some will say it is a hornet. The explanation is that the term « hornet » refers to a very large wasp.
