It is cool as hell, and for anyone who's going "huh?", I'm going to get this half wrong, but it has to do with making sure they don't fall into "rythem" with their predators cycles. The odds of synchronizing to a prime are lower (because years are integers and a prime can only be in sync with itself or larger, not smaller).
Trees will have mast years on primes where they'll produce just a crazy amount of acorns. Because they haven't in so long, the squirrel population etc didn't explode. So they'll feast that year but can't get to them all, and while the population of squirrels might grow that year, next year is a low acorn year again.
Is this why the pon farr is every 7 years
I just want to say I needed a laugh this morning and you delivered lmfao. Thanks stranger.
Last year winter my acorn problem was insane! Not so bad this winter
Inspected numbers and choice numbers just aren't as good.
1803? So the cicadas are a key part of the plan for expanding the power of the judiciary?!?!!!
I remember a huge cicada emergence when I was a kid in the 1980s. You couldn't get a car out of the driveway without driving over dozens of them.
Same, I'm wondering how this will compare.
I still remember the crunching.
And the TASTE
I wonder if you could capture a high quality, multitrack recording of this emergence event to get a multidimensional audio sample from unique times/geographies where these groups emerge.
With an audio sample that could only come from this specific event every 200+ years, you could set up a program that survives your own death and triggers only when it happens again.
I'm not sure what the utility would be, but I'd watch it on Netflix for sure.
Oh God the noise will be deafening. 😬
Mawp
What?
IT'S ALREADY HAPPENING. NOBODY CAN HEAR ME OVER THE CICADAS! 😱
Is this bad?
No, they're harmless and they don't even do much damage to plants because they mostly eat plant fluid in twigs, which trees and bushes usually survive just fine, even with a huge number of cicadas on them.
They're just a big mess.
No, they don't cause damage on their own. Birds get a windfall of big nutritious bugs. Humans might be a little creeped out.
Plus everywhere you go sounds like one of those old sci fi movies
I ate one once. 5/10, would be better deep fried.
Dehydrated and seasoned.
Now people will know what having tinnitus is like!
I genuinely love the cacophony of cicadas and I live in the Midwest so I’m thrilled for this!
spawn more overlords blerching regurgitation gurgling neighing sounds
Insufficient minerals
We require more Vespene gas
Keanu Reeves remembers it like it was yesterday
Nic Cage too
I miss being able to make this joke about Dick Clark. 😢
Emm, with the climate change and pollution, should we panic if they don't show up?
The last major brood batch showed up a couple years ago. I think it’ll be fine.
It showed up but it was way smaller than it was 17 years prior.
'the world' then lists only places in USA.
You do it to yourselves..
What is the US if not a place in the world + that is watched?

For some reason, I was thinking it was a few years more recent than 2011 the last time the Southern Brood emerged in my area. I have a memory of going for a hike in a wooded park, and there were so many of these cicadas that their individual calls just blended together into an almost ethereal low hum. Just didn't realize it was that long ago.
Since childhood, I've always thought cicadas were really cool critters. Their calls are the quintessential soundtrack of summer days for me.
I don't formally track things, but I do pay attention to when I first start noticing cicada calls each year. I had noticed that they have seemed to emerge later and later the past 4 or 5 years. In 2023, the first time I noticed any calls at all was near the end of June. Normally I start hearing them around the last week of May to the first week of June.
I also did not see as many cicada molts last year as normal, so I was thinking that it was a smaller emergence than typical. I wonder if it's related to the upcoming 13-year brood getting ready to emerge?
Final note: I went most of my life without knowing that cicadas can "bite". I mean, technically they can't bite because their mouth parts are needle-like, but I found out that they will sometimes jab a human.
One year I had a Disney princess moment where a cicada landed on my finger while I was outside working in the yard. I just left it to do its thing, because again I think they're cool and never had issues handling them before. Several minutes went by, and then I felt a poke in the general area of the cicada -- and then realized it must have mistaken me for a tree and it was trying to feed. I could see it lifting up a bit and making repeated attempts to stab its mouth into my finger. I guess I was the most poplar Disney princess that cicada had encountered that day. Fortunately it wasn't painful, but one of the jabs did break the skin and there was a small amount of blood.
And when the plagues come, the cicadas shall have a taste for human blood. We shall all have numberfour002 to thank for their hunger.
I prefer to believe that I'm uniquely nutritious and irresistibly sweet. And I probably acquired some kind of special powers from my cicada bite that enable me to make anything I touch suck.
What is the best weapon against this insurgence?
Nukes probably.
