The birth scene from Alien was inspired by parasitic wasp embryos!


That’s right; the infamous birth scene from the 1979 horror movie ‘Alien’ was actually derived from something right down here on planet Earth! Parasitic wasp embryos are injected into caterpillars by their mothers, and use a virus in their DNA to paralyze their host. 

For 14 days they peacefully develop. Then, they bite their way out of the caterpillar, and without a second glance begin spinning cocoons. Instead of getting out of there as fast as they can, the brain-addled caterpillars build blankets over their attackers to defend them against predators until they emerge as fully-formed wasps ready to create parasitic babies of their own.
