And speaking of endoparasitoids …

Wasps of the genus Glyptapanteles, also known as “voodoo wasps”, lay their eggs inside various caterpillar species. The eggs hatch and most of the wasp larvae eat their way out of the body of the caterpillar host and begin to pupate.

But some larvae stay behind and take over the caterpillar’s nervous system, effectively transforming the host into a zombie. The half-eaten-from-the-inside zombie caterpillar then proceeds to starve itself to death while protecting the baby wasp cocoons.

No, I’m not making this up.
