Trillions of cicadas will emerge in 2024
Показать описание
Two different cicada broods are emerging at the same time — the first time this has happened since 1803.
The cicadas currently emerging in South Carolina are of the Brood XIX variety, which emerge every 13 years across the Midwest and Southeast. Brood XIII cicadas, mostly concentrated in Illinois, Iowa and Wisconsin, come out of the ground every 17 years.
Once aboveground, the plump nymphs inch their way up the nearest vertical surface — a tree, a fence post, a person standing very still — where they molt one last time, spread their wings and spend the last weeks of their lives desperately trying to mate.
The males develop their signature sound, a loud high-pitched, high-decibel buzz that ideally will attract females. The noise can be overwhelming, but other than that, cicadas are not harmful to humans.
After a few weeks, they will die, also en masse, leaving behind a smelly mess and billions of eggs containing the next generation.
