Researchers named a newfound wasp Ampulex dementor, or "dementor wasp" for short: The name was inspired by Harry Potter's dementors, ghostlike creatures that suck away a person's happy thoughts (and soul, if they're feeling ravenous).

The wasp eats cockroaches in an impressively scary way. It injects venom into the cockroach's belly, turning its prey into an immobile "passive zombie," the researchers told Live Science in May. But the venom doesn't actually kill it, meaning the cockroach gets eaten alive by the dementor wasp afterward.
