Tiny fairy wasps are so small they can lay their eggs inside other insects eggs, but they punch above their weight when it comes to keeping pests down.
To understand why insects sting and why the stings of such tiny animals hurt so much, we first needed a way to measure the pain they cause. So I created a sting pain index.
