Scientists studied how cicadas pee. Their insights could shed light on fluid dynamics

Cicadas, and the way they urinate, offer a 'perfect' lab for understanding fluid dynamics at very small scales, researchers say
A cicada perches on a picnic table in front of Nolde Mansion in Cumru Township, PA in May 2021. New research shows that these insects urinate in a surprising way.

This spring and summer, across the Midwest and Southeast United States, cicadas will crawl out of their underground burrows by the trillions to mate — due to two different broods of these wingèd insects emerging at about the same time, one on a 13-year cycle and one on a 17-year cycle.

In their brief several weeks aboveground, their mission will be to reproduce. Each male will attempt to attract females by producing a buzzing noise as loud as a lawnmower.

But beyond their prodigious numbers and raucous noise, new research published in reveals that cicadas are special in yet another way — their urination. Based on their size and of pee.
