"Unprecedented Trillion-Cicada Emergence Sweeps U.S., Prompting City Advisories"

Cicada Broods 13 and 19, which emerge every 17 and 13 years respectively, are set to swarm the eastern United States together for the first time in over 200 years. This historic emergence is expected to occur in Illinois and about a dozen other states, with millions of cicadas anticipated to appear for six to eight weeks. While some may dread the swarm, scientists and enthusiasts are eagerly anticipating the once-in-a-lifetime phenomenon, with one professor even creating an app to track cicada sightings. However, concerns about the potential impact of climate change on their population and survival have been raised.
