I found this phenomenon, of extreme parasitism in the insect kingdom, illuminating:

“Imagine you are a caterpillar. You’re sitting down for a nice picnic lunch with your caterpillar buddies in the shade of a eucalyptus tree, munching on the tasty leaves and joking about caterpillar things (“Why did the butterfly get kicked out of the dance? Because it was a mothball! LOLOLOL”), when suddenly, you feel it — a stabbing pain in your stomach. Your whole body starts to quake. You feel heavy inside, like something is trying to break free. Then, something does. One bite at a time, dozens of black larval wasps gnaw their way through your body. Your buddies freak out until they are silenced by the same fate — each one split open by a brood of black alien babies. Needless to say, this is not the picnic you hoped for. Unfortunately for caterpillars, similar incidents happen all over the world, all the time. This is the grim calling card of Microgastrinae, a subfamily of parasitoid wasps that reproduce by injecting their eggs into caterpillars and then allowing their young to literally eat their way through the host bug’s body.
