If you think only zombies are brain hungry than you must see this parasite
We all have seen brain hungry zombies in movies but there is one creature on earth which eats brain inside out of its and finally it decapitate its host’s head.
The Phorid fly is a parasite to fire ants. The fly lays eggs on larva food however sometimes they lay eggs on the thorax of fire ants the larva migrate to the head and then the larva starts eating ant’s brain this period lasts for two weeks in this period the infected ant roams aimlessly. After two to four week it completely eats the ant’s brain after which it releases an enzyme which dissolves the attachment between ant’s head and body eventually ant’s head fall.
After the head is separated from the body it usually takes 2 weeks for the fly to emerge from the head.
You could imagine if some other bigger parasite like this thing could infect humans what would have happened.
