Zombie Spiders Exist
There’s a type of Costa Rican wasp that attacks a local org spider and paralyzes it. From there, it lays eggs in the spider’s abdomen. The spider wakes back up, until about two weeks later, when the larvae that are growing on the spider’s belly take over the spider’s brain, causing it to create a strange web. They then burst out of the spider and use the web to create their own wasp nest.
