Dr. Gene Kritsky (University of Illinois Professor Emeritus of Biology and former Dean of the School of Behavioral and Natural Sciences at Mount St. Joseph University) will present on his book A Tale of Two Broods: the 2024 emergence of Broods XIII and XIV (Ohio Biological Survey, 2024), followed by a discussion. His talk will also discuss some of findings from 2024 emergence, and some of the cultural impacts that occured. Here is the abstract:
Every seventeen or thirteen years, millions of cicadas rise from the soil in the eastern United States to fill the air with their noisy song. But 2024 was a unique cicada year: periodical cicada Broods XIII and XIX emerged simultaneously. The last time these two broods emerged together, Thomas Jefferson was president of the United States. A Tale of Two Broods: The 2024 Emergence of Periodical Cicada Broods XIII and XIX will discuss the natural history, evolution, behavior, cultural impact, and the historical record of these two broods extending back to their first recorded emergence in 1803.
