I love the ones that show up every year, their song is pleasant. I hate the ones that show up every 17 years, the sound is monotonous and sounds like a phaser set on overload; they are far more numerous, and when they die, they stink.
The last time we had the 13 year ones, it was horrible. We were on a camping trip when they began to emerge. Nasty critters! We had to go to Nashville and they were hitting the windsheild by the thousands. It was like driving in a hailstorm. Yuk!
Liberal cicadas?
