Billions of cicadas are set to surface this spring as two different
broods — one that appears every 13 years... and another every 17
years — as they emerge simultaneously!
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.
“It’s rare that we see this size of double brood emergence,” said Dr. Jonathan Larson, an extension entomologist and assistant professor at the University of Kentucky. “We’re talking about an absolute oddity of nature, one of America’s coolest insects.” he said!
Meanwhile, the Northern Illinois Brood, or Brood XIII, emerges every 17 years, but that coincides with the other group this year!.
Though the idea of a cicadapocalypse may seem foreboding, experts predict that the two broods won’t overlap significantly, and the bugs themselves, while loud and numerous, are harmless. (?)
It's just that the damned things are EVERYWHERE!
