The 13-year group, known as Brood XIX, or the Great Southern Brood, is the largest periodical cicada brood, stretching across the southeastern United States.
The Northern Illinois Brood, or Brood XIII, emerges every 17 years.
Periodical cicadas are smaller and mostly black, with bright red eyes and orange-tinged wings and legs.
Billions of cicadas are expected this spring as two different broods — Broods XIX and XIII — emerge simultaneously.
However, predictions of a cicadapocalypse — in which Brood XIII and Brood XIX show up at the same place at the same time — are probably an exaggeration.
