Our next major emergence of the periodical cicadas will start in late April and early May 2024, when two different broods will emerge. The 17-year Brood XIII will emerge in Northern Illinois, while the 13-year Brood XIX will emerge in parts of Southeastern United States. It is not common to have a dual emergence between Broods XIII and XIX. They occur once every 221 years and the last time these two broods emerged together was in 1803. https://cicadasafari.org/
