In the spring of 2024, a once-in-a-lifetime natural spectacle is set to unfold in the eastern United States. Two broods of periodical cicadas, Brood XIII (17-year cicadas) and Brood XIX (13-year cicadas), will co-emerge, creating a chorus of buzzing and chirping that will reverberate through wooded and suburban areas from Maryland to Iowa and southward. This remarkable event, only occurring once every 221 years, offers a fascinating glimpse into the life cycle and behavior of these unique insects.
