Japanese wasps are also referred to as the Asian Giant Hornet and are the largest hornet in the world, growing to around 50 millimetres in length. The Japanese wasps are native to Asia and can ferociously destroy a hole honey bees hive in hours with very little numbers. The Japanese wasps are also known as Giant Sparrow bees. Japanese wasps have unusually large heads that have also large mandibles giving them a very ferocious appearance. They search out and feed on the likes of other large insects such as , mantises and other hornet species. The Japanese wasps will also feast on a honey bees nest with one or two scouts searching for a thriving nest. Once found, the scouts will produce a pheromone that will attract more of their kind and with as little as a dozen Japanese wasps, the bees have no chance against them. With between 20 and 30 Japanese wasps, a honey bee hive of 30,000 bees plus will be destroyed in only a matter of hours with the fight being more like a massacre. Each individual Japanese wasp can kill dozens of honey bees in minutes with their main goal being the collection of the bees larvae and pupae to feed to their own young. With the bees having very little defence, they are doomed from the begging. The Japanese wasps fly around grabbing the bees with their large mandibles and chop their heads of and crush them to death.
