Cordyceps makes ants excrete fluids to increase local humidity, boosting spore survival.
Before death, infected ants are induced to excrete fluids that increase local humidity around the spore release site. This micro-hydration prevents spores from desiccating and increases infection success. Chemical signals from the fungus trigger both ant excretory behavior and location selection. Laboratory observations confirm that artificially blocked excretion sites reduce spore viability significantly. This strategy illustrates an unusual form of environmental engineering mediated through host physiology. Cordyceps combines behavioral, chemical, and physiological manipulation to create optimal conditions for reproductive success. Ants act as living microclimate regulators, extending the survival of fungal spores. Evolutionary refinement ensures precise timing and location of these excretory behaviors. Water channeling represents a rare example of parasitic environmental construction using host resources.
