Historic Double-Brood Cicada Emergence Predicted Across the U.S.

For the first time in over two centuries, Broods XIII and XIX will emerge simultaneously, affecting 17 states.

Two distinct cicada broods, Brood XIII and Brood XIX, are set to emerge together in May 2024, a phenomenon last recorded in 1803.
The cicadas will appear in states from Maryland to Iowa and from Alabama to Georgia, with a significant impact expected in suburban and wooded areas.
This synchronized emergence is considered a rare natural event, occurring once every 221 years, drawing significant attention from entomologists and the public.
Researchers highlight the importance of this event for studying cicada behavior, biology, and potential impacts of climate change on their life cycles.
Citizen scientists are encouraged to participate in documenting this unique occurrence through apps and online platforms, enhancing data collection and research.
