Billions of cicadas expected to emerge in 2021

“Brood X” is the largest colony of cicadas in 17 years, and this species has been recorded in Philadelphia since 1715.

Cleveland, Ohio — Soon they will dig out of the ground, climb tree trunks, drop shells, and prepare to fly their wings.

They are 17 year old cicadas and 2021 is a big year for these big bugs.

Dr. Jean Klitsky is a professor of biology at Mount St. Joseph University in Cincinnati. He is one of Ohio’s top semi-researchers.

The annual cicadas are everywhere, but if you want to see Brood X, head southwest (Roman numeral 10). Kritsky has mapped cicada populations in the area.

“In the west of Cincy, for example in an area called Delhi, 356 cicadas appeared in a square yard,” he explained.

Nymphs appear around tree trunks and hedgerows where the last generation of cicadas dropped their eggs 17 years ago.

Kritsky calls these black-headed and red-eyed beauty “history bugs.” Ask President Theodore Roosevelt.

“In 1902, Brood X appeared in Washington, DC, where he addressed the Arlington National Cemetery, and the cicadas almost overtook him,” Kritsky said.

However, BroodX can also be inspiring.

“In 1970, Bob Dylan was awarded an honorary degree at Princeton University,” Kritsky began. “While he was there, the cicadas were screaming in the background, and he went home and wrote the song,” The locusts sang for me. ” “

Brood X … is it romantic?

“Nothing is more romantic than a cicada wedding, because no one is equally enthusiastic about celebrating the 17th anniversary,” Kritsky said.

Cicadas have a lot of support and there are several websites dedicated to insects. Kritsky and his colleagues have developed an app for smartphones called “Cicada Safari”. This allows citizen scientists to go looking for cicadas and record large, harmless insect photos and short videos.

The information is validated, cataloged, and then mapped to indicate the location of the various chicks. Best of all, the app was free and very useful last year when researchers stayed indoors for COVID-19.

This year, Kritsky is involved in the big task of mapping BroodX in several different states along with Ohio.

“Universit colleagues[ies] People in Connecticut, Maryland, Tennessee are working with me, and we’re all working on this group’s efforts to see what’s going on. “

Cicadas are vector species used in environmental and climate change research. They have been around for millions of years, and scientists can return to colonial America to explore a herd of 17 years at a time.

Brood X should begin to appear in late April or early May.
