Evolutionarily Stable Strategies for Larval Dragonflies
Many animals spend a considerable amount of time and effort watching, stalking, and attacking their neighbors even when it would seem to be mutually advantageous for them simply to ignore each other. A possible example of this paradoxical behavior, interference among dragonfly larvae, is analyzed from a game-theoretic viewpoint to see if such “strategies” appear to be evolutionarily stable. The results suggest that the ever-present possibility of ambush, in which the attacker has a significant chance of seriously injuring the victim, can culminate in “wars of attrition” or pre-emptive aggression by one or both neighbors. Testable hypotheses are presented, and the means of obtaining quantitative predictions from the theory are indicated.
