In this life-abundant world of ours there exists a type of fungus that has the extraordinary power to control the mind of an ant:

This ant latched on to a leaf before dying from infection by the parasitic fungus Ophiocordyceps unilateralis. A fungal stalk has grown out of the carcass and produced a red-orange ball that will release large spores. Researchers propose that the parasite prompted the expiring ant to move into a fungus-friendly spot before death.
