Brood X

Have you seen cicadas, their shells everywhere? I haven't seen a single one yet; but to be honest, I've been forgetting to look. As for their familiar buzzing, I've only heard them twice, and both times I was driving through Ohio County.

I don't know a more familiar sound in the late spring/summer than the drone and the buzz of cicadas. I know the weather is a lot warmer, even humid when the buzzing is there. And when the buzzing all but ceases, all that's left of the insect is a hollow shell that is very crunchy. So why is this upcoming brood so talked about?
