HUDSON -- The 17-year cicadas are back!

They've been spotted in Hudson. Which is a little earlier than expected, especially after last week's snow.

But they will not make any noise for a few more days to a week, said Stanley Stein, naturalist for the city of Twinsburg.

Hudson's cicadas are likely the first in northeast Ohio, he said.

"Animals are digging them up and eating them while in the ground, but they haven't appeared," said Stein on Monday afternoon after checking the woods.

Wendy Weirich, director of Outdoor Experiences for the Cleveland Metroparks, said a few cicadas have emerged in Brunswick, but aren't expected to fully emerge throughout northeast Ohio in the next four days.

Cicadas emerge from the ground when the temperature 8 inches underground hovers around 64 degrees for about four nights in a row.

After the cicadas emerge, they walk around, climb trees and shed their skin, Stein said. Once their wings harden they start to fly.

"Once they are up in the trees they start singing and courting and mating," he said.

Only male cicadas make the sound, according to cicadamania.com. Males have organs on their abdomen called tymbals. Muscles pop the tymbals in and out, which creates the sound we hear.
