Part of Illinois to See 2 Simultaneous Groups of Cicadas

This summer, millions of cicadas will emerge simultaneously across the United States. They are part of a group called Brood XIX, four species that appear every 13 years in the Southeast. Another group, Brood XIII, is made of three species that appear every 17 years in northern Illinois. Researchers say that means part of the state will get hit with a double whammy of the uprising bugs. Experts say it’s the first time in more than two centuries that the two broods are emerging at the same time in neighboring areas of the state. The broods will not necessarily overlap but emerge close to each other in the Springfield and Urbana-Champaign metropolitan areas.
