The Phenomenon of Periodical Cicadas Emergence

Billions of cicadas, after more than a decade underground, are emerging, creating a noise as loud as a jet engine. Co-emergence of two broods, Brood 13 and Brood 19, is occurring for the first time in 200 years, making this event highly rare. The cicadas, with a unique life cycle spent mostly underground as nymphs, emerge to mate after years of feeding on tree sap. They synchronize their emergence based on the soil temperature and can transform entire ecosystems.
