How the Zombie Fungus Takes Over Ants’ Bodies to Control Their Minds

One of the most famous fungi in the world is the “zombie ant fungus” aka Ophiocordyceps unilateralis. It takes over the mind of an ant, causing it to climb up a branch and cling to the underside of a leaf before mummification. Once locked in place, the mushroom-like fruiting body of the cordyceps sprouts from the ant and eventually releases its spores.

To find the world’s most sinister examples of mind control, don’t look to science fiction. Instead, go to a tropical country like Brazil, and venture deep into the jungle. Find a leaf that’s hanging almost exactly 25 centimeters above the forest floor, no more and no less. Now look underneath it. If you’re in luck, you might find an ant clinging to the leaf’s central vein, jaws clamped tight for dear life. But this ant’s life is already over. And its body belongs to Ophiocordyceps unilateralis, the zombie-ant fungus.
