The first thing they do is climb a tree and shed their exoskeleton. Leaving a shell of their former selves behind, the males begin their mating song which can be quite loud because there can be, quite literally, millions of them.
After 17 Years of Quiet, an Army of Cicadas Are about to Emerge in Parts of The US | Science Alert
" Periodical cicadas are considered some of the loudest insects on Earth, and scientists say their alien-like wail can reach over 90 decibels, which is as loud as a lawnmower. "
They're not kidding about "an Army" either. In some parts of Virginia, West Virginia, and North Carolina they are expecting as many as 1.5 million cicadas per acre.
I remember when they came to northern Illinois in 1973. I was ten. I was so grossed out, I didn't want to go outside. It was like a zombie apocalypse except it was a swarm of bugs. They aren't little either. They are 1-2 inches long, black with large eyes, and they fly. And, they're literally everywhere.
Cicadas in Illinois | University of Illinois Extension
" In 1990, there were reports from people in Chicago having to use snow shovels to clear their sidewalks of the dead cicadas. "
Eeeewwwww.
I vowed in 1973 that I would not be living in Illinois in 1990, seventeen years later, and I wasn't. By then I was in Seattle - about as far away as I could get - and I haven't seen a cicada since.
I hope I never do.
(My skin crawls just thinking about it.)
Just a heads up if you are living in northern Illinois. The cicadas will be back in 2024. Known as the Northern Illinois Brood, they have a reputation for the largest emergence of cicadas known anywhere.
I'll be somewhere else.
