Stinging wasps are precious, not pointless, say scientists

Much-hated insects are voracious predators of pests, produce powerful antibiotics and pollinate plants

For those who have asked what the point of wasps is, there is now a comprehensive answer. They are voracious predators of pest insects, produce powerful antibiotics in their venom, pollinate plants and even make a nutritious snack.

The benefits to humans of the much-hated insects are revealed in the first major scientific review of the ecosystem services they provide. It focused on the 33,000 known species of hunting wasps, which carry stings and live in every corner of the world.
