Depending on where you live in Illinois, you may already be experiencing the historical emergence of cicadas, or you're just about to have it happen.

According to all the cicada experts out there, we're just not going to be able to avoid the emergence of billions, if not a trillion, cicadas over the next week or so. All the conditions that cicadas need for this massive, multi-state orgy they've been planning for 17 years are in place, and they're ready to rock.

By "rock" I mean make noises louder than a lawnmower or motorcycle, mate until they're near death, and literally urinate all over the entire state.

Take a look:

Here's basically how it breaks down. Cicadas, like many creatures, need to regulate their body temperature, and to do so they drink a lot of something called xylem. Xylem is, according to, "hollow, tube-like tissue, almost like tiny pipes that carry water and minerals to every part of a plant."

So the cicadas load up on the water and minerals in the xylem to cool off, and then once they're cool, they quickly squirt the stuff right back out. That's no problem if there are just a few cicadas doing it, but when a few hundred thousand or a million cicadas do it, it's really pretty noticeable.

Especially if you're right under them when it happens. And, since cicadas spend a lot of time in trees...

When you think about it, so is human pee--but I still don't want to be a target for it. According to, "standing beneath a tree buzzing with cicadas on a hot day can feel like being caught in a rain shower. Though getting doused with cicada juice isn't exactly pleasant, it won't hurt you. The "pee" is actually excrement commonly known as honeydew."

The pee from the Brood X cicadas native to the eastern U.S. is more of a spritz, but in other species, like the ones emerging in Illinois, it's going to be a full stream.
