Every 17 years, in the summer, thousands of millions of cicadas known as Brood Ten invade the Eastern United States from New York to Missouri and as far south as Georgia. The largest numbers will appear in parts of Indiana and Ohio. People there can expect between one-hundred-thousand and more than one-million cicadas per hectare in places.
For the past seventeen years, they have been living underground, getting food from tree roots. Then they come up out of the ground to mate before they die. Male coicadas make noise to attract females. Experts say that many animals love to eat cicadas, including birds, snakes, squirrels, cats and dogs.
Some people eat cicadas too, but experts say, they should cook the insects first.
