Ampulex compressa – This wasp preys on cockroaches and turn them into zombies that start feeding on their young. The female wasp stings straight into the brain of the roaches, disabling them from escape reflex. The female wasp then leads the roach back to her underground nest, lays her egg on its belly and seals it in. The larvae hatches and borrows themselves into the body of the roach where they devours the insect from inside and form a cocoon. Later they emerge out from the insect body as a new adult.
