After cordyceps spores Pierce an ant's exoskeleton, they cause convulsions

After Ophiocordyceps spores pierce the ant's exoskeleton, they set off convulsions that make the ant fall from the tree. The fungus changes the ant's behavior,
compelling it to wander mindlessly until it stumbles onto a plant leaf with the perfect fungal breeding conditions, which it latches onto.
The ant then dies, and the fungus parasitizes its body to build a tall, thin stalk from its neck.
