Though they’re not considered harmful, cicadas may be annoying to some people when they emerge in southern states this year. But it’s unlikely Hoosiers will have to worry about the little buzzers.
Normally, between late April through July, billions of cicadas emerge as adults from 17 years underground. IU biology professor Keith Clay says the last emergence of Cicadas – as many as 100 billion of them — was in 2004.
“Despite our advanced civilization and technology, Cicadas represent a reminder that there are certain things in nature that are beyond our control,” Clay said. “We would find up to 200 per square meter, that’s 6 or 7 million per square mile,” he said.
Though some states south of Indiana did see Cicadas this summer, Clay says Hoosiers don’t have to worry this year.
“They did emerge. They’re grouped into Broods and each Brood comes out in certain parts of the country during a certain year,” Clay explained.
“This year Brood 19 emerged, its distribution geographically south from here parts of Missouri, Arkansas, Louisiana, Tennessee, North and South Carolina.”
Indiana isn’t expected to see another Cicada spawning until 2021.
