Cicada 2024 Factset. For the first time in 221 years, this spring will see billions, if not trillions, of cicadas take to the skies in a rare synchronized. That’s because 2024 will see two separate batches of periodical cicadas emerge en masse, spread across much of the eastern half of the u.s.
Cicadas count years, likely using the flow of tree sap. It sounds like spring 2024 will be abuzzing as more than a trillion cicadas are expected to appear across the u.s.
