Unprecedented Cicada Emergence Expected This Spring

First simultaneous appearance of Brood XIX and Brood XIII since 1803 to span across Midwest and Southeastern U.S.

Two broods of cicadas, Brood XIX and Brood XIII, are set to emerge simultaneously in the U.S. this spring, an event that hasn't occurred since 1803.
The cicadas will begin to appear in late April, with their emergence triggered when soil temperatures reach about 64 degrees Fahrenheit.
Brood XIII is expected to be seen in states like Iowa, Wisconsin, and possibly Michigan, while Brood XIX will emerge in states including Alabama, Arkansas, Georgia, Kentucky, Louisiana, Missouri, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, and Virginia.
Cicadas are harmless to humans and beneficial to local ecology, providing a food source for birds and contributing to soil aeration.
The next co-emergence of these broods won't happen for another 221 years.
