Cockroach Under Remote Control

There is a species of wasp, called Ampulex compressa, that attacks a cockroach by delivering a sting to the roach's midsection to take out its front legs. Then, with all the time in the world, makes its way towards the head and slowly introduces its stinger under the roach's exoskeleton. With the aid of sensors in the stinger, the wasp delivers a precise venom attack to a tiny part of the roach's brain. This knocks out the roach's escape reflex, allowing the wasp to literally drive the roach towards its burrow by pulling on the roach's antennae. Then the wasp lays its eggs on the outside of the roach, and when the larvae hatch they eat through the exoskeleton and develop inside the roach, slowly feeding from its internal organs. After four weeks the new wasp emerges from the roach's body, a la Aliens. Full article here.
