It’s about to be cicada season.

The periodical cicada, back from its 17-year cycle of hanging out underground, is ready to emerge now that the soil temperatures are rising.

That buzzing sound is from the males. They’re looking for a mate.

Hannah Burrak, professor of the Department of Entomology at Michigan State University, says the dog day cicadas will come out when it’s warmer in the summer, and the ones that are about to merge now are a special brood.

“They’re just going to be active later in the summer than our periodic cicadas, because our periodic cicadas start coming out when our ground when the temperature reaches 50 degrees for a reliable period of time, and our annual cicadas will come out later in the summer,” Burrak said. “So we have them here. They’re just not the massive periodic.”

And most of the special periodic cicadas will be found along the lower border of the mitten between Ohio and Indiana and further south when they take over Kentucky and Tennessee.
