The Emerald Jewel Wasp is an evil insect , This creature is the real zombie maker. The female, not being content with just laying her eggs in a hole and hoping the larvae find a way to survive like other insects, makes sure that her larvae will hatch right on top of their preferred food source: a cockroach. The problem with that is a typical cockroach is aggressive, and two to three times larger and beefier than the female. Like a surgeon, the wasp uses her long stinger to penetrate the surprised cockroach, to paralyze and anesthetize the front section of its body. Now, she can take her sweet time, to make sure the second injection of her stinger is perfectly placed into a specific area of the roach's brain. She injects more venom directly into it, precisely blocking very specific receptors of neurotransmitters that essentially destroy the roach's fight or flight responses and leave it zombified.
