Are They Really Gone?

For most of May we were dealing with a large population of cicadas. My mother did not get to experience their deafening sound or huge orange eyes but I've had my fill until the next batch arrives again in another 10 years. This year's brood was the 13-year species. The 17-year species last arrived in 2004 so in 2021 they will return. They are both considered periodical cicadas.
Apparently, the nasty things live underground and then emerge (like orcs) every 13 or 17 years, leaving a hard shell behind and taking up residence in bushes, on tree trunks, and anywhere else they damn well please. They first arrived around the house at the lake. Then two weeks later they migrated into town (or I guess came out of the ground there) near work. During the hours of 8am and 6pm they were so loud it was difficult to carry on a conversation outside and could still be heard inside. If one landed on you, you either knocked it off or picked it up with your hand, shook it like a maraca (I only saw the male population doing this, most women screeched and fainted) and tossed it aside. I have not heard them in over a week and only occasionally see a carcass (half eaten by birds and Remy) here and there. I think it's over, for now.
