Other wasps — especially parasitic ones — resort to similarly grisly measures to protect their offspring. The parasitic wasp Dinocampus coccinellae, for example, hijacks ladybug bodies, turning its victims into zombie slaves that keep predators away from its larvae. And elsewhere in the animal world, other creatures — even snakes — have taken advantage of the bad reputation of ants to survive. A 2009 study in the journal Insectes Sociaux described how banded cat-eyed snakes lay their eggs in the fungus-filled chambers of aggressive leaf-cutter ants to keep their reptilian babies safe before they hatch.
