This is probably one of the the most chilling of wildlife stories I have ever read. And the video in the article was as scary.
The wasp, which lives in tropical regions of Africa, India and the Pacific Islands, relies on cockroaches for its grisly life cycle. But unlike many venomous predators, which paralyse their victims before eating them or dragging them back to their lair, the wasp’s sting leaves the cockroach able to walk, but unable to initiate its own movement.
The wasp then grabs the cockroach’s antenna and leads it back to the nest. The cockroach walks “like a dog on a leash”, says Frederic Libersat of Ben-Gurion University of the Negev in Israel, who led the research and has previously described the wasps’ behaviour in detail. Once home, the merciless wasp lays an egg on the docile cockroach’s belly, and the larva, once hatched, devours the hapless insect.comments powered by Disqus
