"That's what we kind of associate cicadas, they come out and they do the two best things they're known to do: they'll sing at the top of their voices, and they pee in the wind. And as you're walking, you'll feel this mist because there'll be hundreds of cicadas. And that's when you look up. And if you get close enough, they're actually very good camouflage artists. They are very hard to find because they're brown, they camouflage with the bark," Saad Bhamla, Professor, Georgia Tech School of Engineering (AP)
