Two broods of periodical cicadas are emerging simultaneously for the first time in 221 years.
That's because two broods of periodical cicadas — Broods XIII and XIX — will emerge from their underground lairs simultaneously for the first time in 221 years.
Brood XIX will predominantly appear in southern states, while Brood XIII will appear in a small section of the Midwest — mainly Illinois.
Unlike annual cicadas, periodical cicadas spend years in their underground rooms like brooding teenagers (is that why they're called broods?)
In the case of the next two emerging broods, Brood XIII emerges every 17 years, while Brood XIX emerges every 13 years.
