The birth and death of Periodical Cicadas is by far the best and rarest natural phenomenon that occurs on our planet earth. Cicadas are spectacular insects often making dramatic and sudden appearances.

Having fed the predators, the cicadas leave one last gift for the forest when they die.

This is regarded as the single largest dose of fertilizer in the nature.
