Brood XIII (The Northern Illinois Brood)
Cicadas of the Northern Illinois Brood populate eastern Iowa, the southernmost portion of Wisconsin, Indiana's northwestern corner, and of course, most of northern Illinois. Older brood maps show Brood XII emergences trailing into Michigan, but these could not be confirmed in 2007, when Brood XIII was last seen.
Future Brood XIII Emergences: 2024, 2041, 2058, 2075, 2092, 2109
Brood XIV
Most of Brood XIV's cicadas inhabit Kentucky and Tennessee. Additionally, Brood XIV emerges in Ohio, Indiana, Georgia, North Carolina, Virginia, West Virginia, Pennsylvania, Maryland, New Jersey, New York, and Massachusetts. These cicadas emerged in 2008.

Brood XIX
Of the three extant 13-year broods, Brood XIX covers the most territory geographically. Missouri probably leads in populations of Brood XIX, but notable emergences occur throughout the south and Midwest. In addition to Missouri, Brood XIX cicadas emerge in Alabama, Mississippi, Louisiana, Arkansas, Georgia, South Carolina, North Carolina, Virginia, Maryland, Kentucky, Tennessee, Indiana, Illinois, and Oklahoma. This brood appeared in 1998.

Brood XXII
Brood XXII is a small brood in Louisiana and Mississippi, centered around the Baton Rouge area. Unlike the other two extant 13-year broods, Brood XXII does not include the newly described species Magicicada neotredecim. Brood XXII will emerged in 2001.

Brood XXIII (The Lower Mississippi Valley Brood)
Brood XXIII cicadas live in those southern states that surround the mighty Mississippi River: Arkansas, Mississippi, Louisiana, Kentucky, Tennessee, Missouri, Indiana, and Illinois. The Lower Mississippi Valley Brood was last observed in 2002.
