Cicadas Will Be Buzzing Later This Spring and Summer
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?
