Every 221 years, two major cicada broods, XIII and XIX, emerge together. The last time this happened, Thomas Jefferson was president of the United States

Once out in the world, adult cicadas ditch their nymphal skin. The skin splits and the cicada comes out — head first, then back. Once they pull their abdomen free, they are white in color. It takes about an hour and a half for cicadas to transform to black with red eyes.
The Cicada Safari cellphone app was created by Dr. Gene Kritsky and Mount St. Joseph University. The powerful crowd-sourcing tool, first tested in 2019, lets anyone with a cellphone turn into a citizen scientist during the emergence.

Periodical cicadas spend most of their lives underground, unearthing every 13 or 17 years when soil temperatures hit 64 degrees to mate and lay eggs — marking the start of a new generation of that particular brood.
