Wasp Image (IMAGE) Simons Foundation Caption A specimen of Megaphragma viggianii, a parasitic wasp the size of some single-celled organisms such as amoebas. The tiny insect exhibits complex behaviors such as flight despite its small stature and brain, making it a useful tool for understanding how brains work. In a recent study, researchers at the Flatiron Institute and their colleagues mapped out the wasp’s full early visual system.
