Zombie Roaches

Ampulex compressa is a wasp that uses its stinger to temporarily paralyze and then hot-wire a cockroach so that the wasp can "drive" the larger critter home, where it can lay its egg on the roach host and seal it into a nursery. When the egg hatches, the larva chews its way into the host, where it feeds itself and then spins a cocoon.

Carl Zimmer writes about how complex all of this really is.
