If you're a fan of Harry Potter, you know all about Dementors and what they do. A Dementor is a dark creature that once guarded Azkaban prison, then turned to work for Lord Voldemort. It's a creepy, wraith-like thing (it looks very much like a ring wraith from Lord of the Rings, actually) that can suck out your soul with it's Kiss, leaving you an empty husk. That's what scientists decided to name a wasp that apparently does the same thing.
The Dementor Wasp stings cockroaches to render them into passive zombies that are able to move, but no longer control their own movements. Once the venom sets in, the wasps then drag their prey to a safe area to devour it. Pretty disturbing, isn't it?
