A future generation of antiaircraft missiles could be made far harder to dodge by a guidance system inspired by the flight of dragonflies and hoverflies. The missiles will mimic a strategy called motion camouflage, which predatory insects use to trick prey into thinking they are stationary. Insects that use this technique sneak up on their prey in a way that makes them seem stationary even though they are in fact moving closer. They do this by keeping themselves positioned between a fixed point in the landscape and their prey.
