Because of its apparent ability to "rebirth of the earth", the cicadas represent the resurrection and immortality in many cultures. In Taoism are the symbol of Tsien, the soul leaves the body after death.
had in Greece the cicada as a pet. were famous in antiquity and that became the symbol of music. Plato was unknown to me his love of fables, he explained that the cicadas were men whose devotion to music was so large that it consumed and the only thing left for them was their music. I do not know where you are going to stop the reputation of Plato from this story. I limited to pick it up and, therefore, I take responsibility for that claim.
What is Aristotle's account he liked fried, is much more believable. Even today, men in Asia, Africa and Australia, consumed. I guess the women also have to eat while cooking to everyone's taste, such as "al dente", "a la carbonara 14", etc. Native Americans, ie Indians, fry and eat them like popcorn. are surprisingly meaty and have a taste reminiscent of asparagus.
Among the Australian cicadas are some species with curious names such as: greengrocer, baker Mealy, battery double, cherry nose or bladder.
One species, the Magician Septemdecim, widely dispersed in eastern United States experienced an underground life, preimage, whose duration ranges from 13 to 17 years, can count, though no one has yet managed to discover how they do. What is true is that match their life cycles with prime numbers higher on 13 or 17. have assured that trillions of eggs hatched one night, but at unpredictable times, literally, flood their predators. These the gorge until it can no longer, but without the population of cicadas damage. There are thirty different nests each of which were incubated at different times. cycles 13 and 17 coincide only once every 221 years. Of these tricks should have taken note Co. and others of the same species.
During his long confinement underground, the larvae use their depositions to seal the cells to protect them from flooding. Still, it is estimated that killed 98% of the larvae before they feel the need to incubate. Those that survive, leave the stage of larva, mating frenzy. After mating, females perch on the branch of a tree and practice oblique incisions, vertically injecting eggs into the holes, last six weeks, the birth place of the tiny larvae that, when opened, falling to soil. His front legs, equipped with thick, jagged femurs, good organs are the larvae used excavators to sink immediately on earth.
Meanwhile, adults, mostly die within fifteen days after mating, thus providing a huge injection of nitrogen to the forest floor. These cicadas have not yet discovered the value of chastity.
larvae, nymphs and adults feed exclusively on plant sap. larvae after various and numerous silent have the outlines of the wings and the larvae become lymphs; then they will head to the surface and emerge into the light. Fixed remain motionless on a log until adulthood, breaking the shell, life goes on.
all know that cicadas are the loudest insects but may not know it all, which only males sing, and usually the hottest days of summer. Some species can reach 120 decibels. hears is nearly two miles away. As the rockers!
Cicadas usually sing numerous groups and the main function of this song is the bridal claim. Some species practice "protest song" if you feel annoyed. Each species has its own set of calls that they can identify females.
To perform this song -call sing anything, "the males are provided with a device estridulante two membranes covering oval. The structure of this device is very complex because it comprises a pair of plates called "toms" and attached a large cavity that functions as a sounding board. contractions of muscles producing the drums vibrate with them the distinctive chirp.
