When are the Brood X cicadas emerging? Facts about the large and loud bugs that have sparked culinary and musical inspiration

Billions of the 17-year variety of cicada will rise from the ground in the coming weeks. They are edible, and at least one song has been written in tribute.

TOLEDO, Ohio — Brace yourselves; The cicadas are coming. Lots of them.

After 17 years underground, billions of Brood X cicadas are set to emerge across the eastern and midwestern United States in the coming weeks. The buzzing creatures will start to pop up in an area bounded by Illinois to the west, New York to the east, and Georgia to the south.

Ohio is considered to be a hot spot for the Brood X variety, which is among the largest in population of all the 17-year periodical cicadas, according to Earthsky.org. They spend 17 years underground, feeding on sap from tree roots.

They emerge in the 17th year all at once to avoid being eaten by predators. The females are silent, but males make a hissing sound to call out for a mate.

Adult cicadas mate and the female lays eggs, which will fall from trees and sink into the ground, starting the process all over again. Then, the adults die.

When exactly will the cicadas appear? According to USA Today, they dig their way out of the ground when the soil temperature reaches 64 degrees. This usually happens the first or second day the air temperature reaches the low 80s.

Despite their appearance, cicadas are harmless to humans. They do not bite or sting.

According to the Ohio Department of Agriculture, cicadas will not harm your home, garden, crops or animals. However newly planted trees should be wrapped in a mesh net.

In large groups, the noise from Brood X can reach 100 decibels. That's equal to a lawnmower starting or a low flying airplane.

Ohio counties likely to see the most are Defiance, Franklin, Greene, Hamilton, Logan and Montgomery.

They can also be eaten, as is common in many countries. If you're feeling brave, there are several cookbooks available online.

Jerome F. Grant, professor of entomology at the University of Tennessee Institute of Agriculture, says that yes, the googly-eyed insects are edible.

Grant told our sister station, WBIR in Knoxville, that when this batch emerges there could be more than 1 million bugs per acre.

If you want to eat them, they're tastiest when they come out of the ground in the morning and before their shell hardens.

"They are related to shrimp and lobster," Grant said. "You could use them in the same recipes."

If you are cooking up the adult cicadas, you can pull the wings and legs off to reduce the crunchiness.

Singer-songwriter George Peter Block Jr., now of northern Michigan, used the cyclical appearance of the cicadas as an inspiration for an autobiographical song, titled "Seventeen Year Cicadas." 

In it, Block recalls the emergence of cicadas "everywhere" during his daughter's first birthday party outdoors in the Chicago suburbs, calling it unforgettable. 

And, like clockwork, back the noisy bunch appeared for her high school graduation, marking yet another milestone in the family's life. 

"Now my daughter is almost 32 years old, so the rest of the song is fictional," Block said. "The Seventeen Year Cicadas in the Chicago area on a slightly different cycle than Toledo. The Seventeen Year Cicadas will emerge again in the Chicago area in 2024."


Block laments the lack of abundant cicadas in northern Michigan, but holds on to "fond memories of sitting on the porch in the Chicago suburbs in the summer, drinking a beer, and listening to the drone of the cicadas in the tree canopies. ... That pulsating drone that gets louder, then quieter, then louder again, etc. It sounds so other-worldly, almost extraterrestrial."
