Cordyceps makes ants leave their colonies before death to prevent predators from consuming infected hosts.
Infected ants exhibit social withdrawal, leaving protective nest environments before death. This isolation ensures that spores are released away from predators that might consume infected ants prematurely. Behavioral observations confirm that infected ants climb vegetation alone, minimizing colony contact. The fungus manipulates neurological and hormonal pathways to trigger this distancing behavior. Social isolation reduces interference from conspecifics and enhances spore dispersal efficiency. The strategy is critical because ant colonies are efficient at removing diseased individuals. By steering hosts into isolated zones, Cordyceps increases reproductive success while avoiding predation losses. Evolution has honed these subtle behavioral manipulations for maximum survival. Behavioral isolation represents a tactical use of host movement to optimize parasitic outcomes.
