"2024: Historic Cicada Invasion Set to Sweep Across the U.S."

In spring 2024, over a trillion cicadas from two broods, XIX and XIII, will emerge simultaneously in 17 U.S. states, marking the first time in 221 years that these periodical cicadas will co-emerge. The emergence is expected to create a significant buzz and will overlap in areas across Indiana and Illinois. While the noisy insects are largely harmless to humans and animals, their exoskeletons may upset some animals' stomachs, and the emergence is anticipated to last from mid-May to June.
