Got your earplugs at hand? Due to a rare dual-brood emergence, here come one trillion cicadas to serenade us.
This spring, for the first time since 1803, two cicada groups known as Brood XIX, or the Great Southern Brood, and Brood XIII, or the Northern Illinois Brood, are set to appear at the same time, in what is known as a dual emergence.
The last time the Northern Illinois Brood’s 17-year cycle aligned with the Great Southern Brood’s 13-year period, Thomas Jefferson was president. After this spring, it’ll be another 221 years before the broods, which are geographically adjacent, appear together again.
The first wave of periodical cicadas, which differ from those that appear annually in smaller numbers, will show up in northern Louisiana, southern Arkansas, Alabama, Mississippi, northern Georgia, and up into western South Carolina, said Gene Kritsky, a retired professor of biology at Mount St. Joseph University in Cincinnati,
Then it’ll be central North Carolina, eastern Tennessee and northern Arkansas, followed by southern Missouri, southern Illinois and western Kentucky. Finally, he said, the cicadas will appear throughout central and northern Missouri and Illinois, northwestern Indiana, southern Wisconsin and eastern Iowa.
