If you live in one of the lucky (or should we say unlucky?) states, this spring is bringing a once-in-a-lifetime event just outside your window.
Starting in mid-May, 16 states in the South and Midwest will experience the emerging of two different cicada groups simultaneously, something that hasn’t happened in 221 years and won’t again until 2245.
The two groups, Brood XIX and Brood XIII, are periodical cicadas that typically emerge separately every 13 and 17 years, respectively.
But this year, they will emerge from their years spent underground together.

Brood XIX will make an appearance in southeastern Oklahoma, specifically McCurtain County. Brood XIX is also the largest known group of periodical cicadas, stretching across 14 states.
In total, Brood XIX and Brood XIII will emerge in 16 states this year:
