What's the biggest wasp?
Asian giant hornet
The Asian giant hornet (Vespa mandarinia), including the subspecies Japanese giant hornet (V. m. japonica),[2] colloquially known as the yak-killer hornet,[3] is the world's largest hornet, native to temperate and tropical Eastern Asia. They prefer to live in low mountains and forests, while almost completely avoiding plains and high-altitude climates. V. mandarinia creates nests by digging, co-opting pre-existing tunnels dug by rodents, or occupying spaces near rotted pine roots.[4] It feeds primarily on larger insects, colonies of other eusocial insects, tree sap, and honey from honey bee colonies.[5] The hornet has a body length of 45mm (1.8in), a wingspan around 75mm (3.0in), and a stinger 6mm (0.24in) long, which injects a large amount of potent venom.[6]
Wasp
Wasps have appeared in literature from Classical times, as the eponymous chorus of old men in Aristophanes' 422 BC comedy (), "The Wasps", and in science fiction from H. G. Wells's 1904 novel "The Food of the Gods and How It Came to Earth", featuring giant wasps with three-inch-long stings. The name "Wasp" has been used for many warships and other military equipment.
