sciencehabit writes: The green-eyed wasp Dinocampus coccinellae turns ladybugs into zombie babysitters. Three weeks after a wasp lays its egg inside the hapless beetle, a wasp larva bursts from her belly and weaves itself a cocoon between her legs. The ladybug doesn’t die, but becomes paralyzed, involuntarily twitching her spotted red carapace to ward off predators until the adult wasp emerges a week later. How D. coccinellae enslaves its host at just the right time had been a mystery, but now researchers believe the insect has an accomplice: a newly identified virus that attacks the beetle’s brain. The findings raise questions about whether other parasites also use viruses as neurological weapons.
