"Cicada Swarms Peak Across US, Impacting Autism Spectrum and Midwest Residents"

Cicadas from Brood XIII have emerged in some Chicago neighborhoods after 17 years, but sightings are inconsistent across the city. Areas with more greenery like Beverly and Edgebrook report high numbers, while more urbanized neighborhoods like Ravenswood and Logan Square see fewer or none. Entomologist Allen Lawrance explains that cicadas have a patchy distribution and are affected by local environmental conditions, including tree density and predator presence. The current emergence window is closing, and future cicada populations may be influenced by climate change.
