Cordyceps manipulates ants to die at specific heights to ensure spores travel farther and infect more hosts.
Cordyceps manipulates ants to climb to specific heights and attach to vegetation before dying. This height optimization ensures spores are dispersed over the widest area by wind currents. Detailed measurements reveal that most ants die at mid-canopy levels, where air flow and humidity favor spore longevity and reach. The fungus uses behavioral and chemical signals to control climbing duration, gripping location, and death timing. This precise engineering enhances reproductive success by preventing spores from falling into unsuitable microhabitats. The fungus’s ability to manipulate vertical positioning is rare among parasites and requires intricate host control. Field studies show that deviations from these heights significantly reduce infection rates. Cordyceps effectively converts ants into aerodynamic platforms for fungal propagation. This strategy highlights the integration of behavior, physiology, and environmental physics in parasitism.
