The 17-year periodical cicadas are distributed from the Eastern states, across the Ohio Valley, to the Great Plains states and north to the edges of the Upper Midwest, while the 13-year cicadas occur in the Southern and Mississippi Valley states, with some slight overlap of the two groups. For example, broods IV (17-year cycle) and XIX (13-year ...
Map: Cicadas expected to emerge in various parts of the US There could be as many as 1.5 million cicadas per acre, which brings the brood population into the trillions. Unable to view our graphics?
Periodical cicadas will emerge across more than 10 states this spring, but their habitat spans across the eastern and midwestern U.S. Brood XIX is geographically the largest of all broods, living ...

[1] All other cicadas from other biogeographic regions produce annual broods, so the distinction is not made outside of North America.
