Who knew again?

It wasn't me. Probably. But still, this is the worst bit:

Over a period of eight days, the wasp larva consumes the roach's internal organs in an order which guarantees that the roach will stay alive, at least until the larva enters the pupal stage and forms a cocoon inside the roach's body.

The larva instinctively knows to do that. Apparently it's possible to be born knowing how to prolong suffering in the natural world.
