Fairy Wasp is Smaller Than an Amoeba

It’s pictured next to a Paramecium and an amoeba at the same scale. Even though both these creatures are made up of a single cell, the wasp – complete with eyes, brain, wings, muscles, guts and genitals – is actually smaller. At just 200 micrometres (a fifth of a millimetre), this wasp is the third smallest insect alive and a miracle of miniaturisation.

It has no heart, neurons without a nucleus, and only lives an action-packed 5 days. Enough to lay its eggs and move on.
