15. Jewel Wasp
The Jewel Wasp is known for being parasitic. When females want to have their young, they will find a cockroach to lay their eggs in. The wasp will sting the roach in the brain, causing it to become immobile for a period. Yet it will still be able to walk around and some other complex behavior. The wasp will then literally drag the cockroach back to its burrow of sorts where it will lay one egg inside the insect on its abdomen.

This wasp will actually allow the cockroach to go back to its own home too. The wasp will usually follow it and block up the entrance to its home, trapping it inside. About three days later, the wasp larva will hatch and begin to eat its way out of the roach from the inside. Literally, the mother wasp controlled the cockroach and forced it to become a walking zombie that will then become the larva’s own personal zombie that it can control. Imagine if this were used in humans.
