Periodic Cicada: The Nexus of Time
Living longer than any other Insects, Periodical Cicadas emerge as a single Brood. Each Brood is spaced 13 or 17 years between emergences. This long period prevents Predators from timing their activities to eat the Cicadas. The prime numbers of 13 and 17 insure that nothing can adapt to the Brood Cycle.
Called Periodical Cicadas (Magicicada)), these Insects differ from their cousins Locusts. Unlike Locusts, Periodical Cicadas do not jump. They seem like Locusts because of their larger broods that overwhelm predators by their sheer numbers. After spending many years developing underground, They come up for only two months. Then, the Adults mate and die. Then years go by before another mass emergence.
Besides Periodical Cicadas’ size and numbers, what also makes Them outstanding is their song. Male Periodical Cicadas makes the loudest sound in the Insect World. By vibrating the ribbed plate in a pair of amplifying cavities at the base of his abdomen, Male Periodical Cicada can make his sound heard for long distances. A whole chorus of these whirring sounds resembles a deafening roar of hundreds of kazoos played at once.
Many people have heard Periodical Cicadas, and have not realized it. The sound tracks of many science fiction movies that feature UFOs use the Cicadas’ droning to signal the sound of the alien space ships. Think space aliens, and you associate Periodical Cicadas with them.
The lesson of Periodical Cicadas is living at the nexus of time. For Periodical Cicadas, time merges into one Brood. When They emerge in the present, Periodical Cicadas encourage people to remember the past. Also, They prompt people to think about what the future will bring. In the present, their numbers simply overwhelm people. Periodical Cicadas bend time into a prism of past, present, and future in one moment.
