Remember the horrifying dream sequence from David Cronenberg's The Fly, where Geena Davis gives birth to a squirming, slimy, ten-pound larva? Well, brace yourself, because a creature almost exactly like it actually exists.
Native mostly to Central and South America, the Hercules beetle (species: Dynastes hercules) is king of the rhinoceros beetle family, and one of the world's largest insects. It also looks a lot like the giant space-bugs in Starship Troopers, and no doubt inspired the design of some of the creatures in that film.
Its babies are just as large, with some specimens reaching nearly five inches. But instead of looking alien and exotic, they just look... well, disgusting. Sure, most of us have gone through an awkward phase growing up, but... damn.
