Okay. I've just noticed something pretty cool... at least to me anyways. So with the Magicicada cassini member of the cicadas ( the ones that make the loud electrical noise) I've noticed the noise wax and wane in 5 second intervals. So looking at the tree that I mentioned in my backyard, where they all seem to be hanging out, I looked closely if I could see any flying pattern with them related to their wax/wane noise levels. Sure enough, I observe most of them take flight during the 2-3 seconds when their noise output is lower. Then in those 2-3 seconds that they've landed on twigs/leaves/branches the noise level crescendos to a peak before lowering again before they take their few second long flight and repeat the pattern indefinitely.
I just thought it was something fascinating to share that I just noticed with the cicadas today.
