Ophiocordyceps Unilateralis

One example of a parasitic fungus is Ophiocordyceps unilateralis, commonly known as the "zombie-ant fungus."

- Host: Carpenter ants (specifically those in the genus Camponotus).
- Mechanism: The fungus infects the ant, controlling its behavior. It compels the ant to climb a plant stem and bite a leaf or twig, where it locks its mandibles in a "death grip." The fungus then kills the ant and grows a stalk out of its head.
- Purpose: This stalk releases spores that rain down on the forest floor, infecting other foraging ants and continuing the cycle.
- Significance: It's a classic example of a parasite manipulating its host's behavior to enhance its own reproductive success.
