This story suggests that the periodic cicadas that have come to surface in the east this year come out in such density as to provide "predator satiation." Evidently the cicadas have lost the fight-or-flight hardwiring and have "evolved" to an insurance-pool approach to the survival of the species. The idea is that the cicadas come out in such a density that natural predators cannot possible eat them all and therefore some (cicadas) are guaranteed to survive.
