Why 2024's cicada emergence is so rare | BBC Global
Periodical cicadas have a very strange lifecycle.
They spend 13 or 17 years underground (depending on the brood), and then suddenly emerge in their billions over the course of a few weeks.
And now, in 2024, an ultra rare "dual emergence" of cicadas is happening - with two different broods of emerging at the same time. It has not happened for 221 years - and won't happen again for another 221 years.
Cicada expert Dr Gene Kritsky explains it all.

😳 17 years living underground is a long time. . wonders of nature.
We are currently in the beginning of two brood emergences in central Illinois. They are absolutely everywhere. On our trees, all over our yard, on our basketball hoop, on our parked cars, on our wooden swing set, in the garage, on our mailbox, on the house, and occasionally on my wife who proceeds to get terrified.

You know that strange buzzing sound you hear in the background of favorite anime? Those insect sounds are cicadas. Japan has about a dozen of species and they are known to spend anywhere from 3 to 6 years underground but they come out every year. We don't have any periodic leaping swarms. The number of swarms depends on factors like weather and temperature. They're usually heard annually from June to September.

True and they all seem to congregate around my house in Japan and i absolutely hate it. The sound is unbearable and it makes the heat feel even worse than it is. And because there are at least 10 species here, we have 10 different sounds. I like the Higurashi because they start making noise at night and the sound is relaxing rather than irritating. But all the others are a nightmare. What do not like about cicadas in Japan is that they attract not just bird which crap everywhere but also other insects like the dreadful giant Japanese hornets or wasps Oosuzumebachi, who also congregate around my house and terrify me, but (the disgusting tho9ugh harmless) huge japanese roaches which eat the dead cicadas and where you have roaches you have spiders big enough to eat them and you finally have the worst of all, the ones that eat the roaches and the spiders and can send me to the hospital and my pets to the morgue, the nightmarish japanese centipede, the Mukade. Apparently ellusive in Japan, probably because they all live underneath my house and all over my garden and sometimes inside my house. I would love to just have to deal with cicadas, and i used to love them as a child when i lived in the south of France and there were no roaches or gigantic spiders and hornets and centipedes. But now, in spite of all my love for Japan, every summer i curse the day i moved into a house surrounded with nature (even though i am still in Tokyo). I am so scared of the insects that i am no longer scared when i see japanese weasels on my house or badgers in my garden and even twice monkeys on the roof (In TOKYO).
I remember a french tourist asking me what the noise was, his little mind was blowing when I told him it was an insect
i love the way their chorus converges and expands until the sound seems to come from everywhere at once

I got to see the total eclipse on April 8 and then the cicada emergence on May 8. I feel lucky.😁I know some people don't like bugs, but I find cicadas to be adorable. The night of May 8, we had a huge thunderstorm. When I got to the office the next morning, there were hundreds of these little guys taking shelter near the front door to my office because it's under a covered patio.
People who live there shouldn't be annoyed by them. Y'all are so lucky to experience this! Wish they didn't take so many years to emerge, they're such interesting and cool insects, love their sounds

There are thousands of species of Cicada and at least one of those emerge every year. Most cicadas are inaccurately named "Annual cicadas" and they spend much shorter periods underground, from 2 to 5 years, like fireflies. "Periodic cicadas" just spend longer underground. But basically every year there are overlapping emergences from different species or from different broods of the same species.

They are cool but they chew up trees so bad that sometimes they die. Three years ago we had a cicaida event and one of our japanese maples died. Our others had long open wounds on every branch that was as thick or thicker than a pencil and our dogwoods are still needing supplemental water and fertilizer to get their previous strength back. Ornamental trees are so expensive. They are cool bugs but the do cause some pretty expensive damage.
It's never a good idea to give a cicada a 10-year amortized loan.

The next common emergence for 13 or 17 years cycles will occur after 221 years. Reason being 13 x 17= 221 which is the least common multiple for prime numbers 13 and 17. Last common emergence was in 2024-221 = 1803
I've never seen the smaller black cicadas, with red eyes, until now. Where i live Mississippi, its always the bigger green cicadas, and they are alot louder. First ever seeing the black cicadas and they are everywhere.

Interesting that 13 and 17 are both prime numbers. The Cicadas clearly have evolved to avoid something as these two numbers are not divisible but by themselves. What is that thing they are trying to avoid is the question

It's a crappy uninformative video but there are actually 7 species of periodical cicadas, and they live in different areas. So no i don't think they are capable of interbreeding.
Another part of why they are unique is that they they are a great food supply for birds, they are completely harmless to people and trees and they are absolutely beautiful creatures.

A lot of natural events this year Total solar eclipse, northern lights and double cicadas emergence
I experienced the emergence of a similar animal here in Sri Lanka, during the weekend trip last week…
I'm in central North Carolina and I've only seen one type this season. Are there only certain areas where you can find both breeds emerging together?
Since I watched this documentary in Netflix, Life on Earth, i was so amazed the life of cicadas. why 17 years? no one knows.
I once found a cicada inside my shoe, and I reacted as if the girl from The Ring came out of the tv
Contrary to popular opinion I actually like the sound of the cicadas. It reminds me of summer time. It is just really annoying to see them everywhere. Especially considering the fact that I HATE bugs. Luckily for me they are harmless and usually stay near trees so you’re not just fighting a swarm everytime you want to get groceries 😂
Welcome to the world young cicadas! I hope you enjoy shrieking to your hearts content 🪲
We have them in Australia. When I was at school, kids would catch them and play with them and carry them around. They are definitely the sound of summer. If the summer isnt hot enough, they won't emerge. Some summers have been too wet and too cool and the cicadas didnt appear -- I missed them.

Oh shoot. I don’t live Illinois. Now may never be able to experience that once in a lifetime experience.
I am curious. If cicadas emerge from under ground why are their shells (not sure the technical term) above ground and not below ground?
Is there a way to differentiate between 13 and 17 year cicadas? or do they all look the same?
Man, nature keeps on amazing us! For the unknown it might be just nuisance but once you get to know about the reason behind it, it just makes sense
Periodical cicadas are awesome, and it’s cool to have a dual emergence with a little geographical overlap. But the reporting on this phenomenon is incredibly frustrating. A dual emergence is not that rare! THIS PARTICULAR brood of 17-year cicadas, and THIS PARTICULAR brood of 13-year cicadas will only sync up once every 17*13=221 years. But almost every year, there is a brood of 17-year cicadas (13 broods, so 13 out of every 17 years). And there are three extant broods of 13-year cicadas. Every possible pairing of broods from each group will have a dual emergence once in each 221-year cycle. That’s 39 years out of 221, or 3 every 17 years-so about once every five or six years, we get two broods syncing up. To suggest that a dual emergence is happening for the first time since 1803 is extremely misleading. This has been your cicada pedantry for the day. Thank you.
Just like Peter Gregory predicted in Silicon Valley. Time to buy Indonesian sesame seed options to profit off of Burger King's sesame seed demand during this dual cicada emergence.
We have the two broods here, if I'm not mistaken. The Pharaoh and the Cassini subspecies.
I wonder if the cycling also is the same in Europe? I would love to hear them again! Greetings from Spain.

My knowledge on Cicadas is very limited, but I wonder if there are external cues which forced them to emerge. Seems obvious, but I am observing Cicadas in India too emerging and flooging the trees in big numbers. Cicadas emerged in USA, India and probably elsewhere in the world. I wonder if the external cues put them into some sort of synchrony.
Wonderful Nature.

They are not bad or as loud as the large katydids, just more of the cicadas. You don't even know wtf is making the katydid sound, if it is mechanical or organic till you go outside and the sound seems to come from all directions.

In Central Florida they tend to do a three-part singing where one cicada sings, a second follows with the same phrase, then a third follows the same way. All until sun set when it is loudest.

This video is somewhat misleading. A group of cicadas will emerge basically every year. There are cicadas that spend shorter times underground, from 2 to 5 years and these are given the misnomer "annual cicadas". The ones that emerge 13 or 17 years are the "periodic cicadas"... but really they are ALL periodic. And most years will see several different broods of different species emerge. The unique thing about this year is the emergence of these *specific* broods.
Do they die after they come up ? Or do they go back underground to have the babies? So weird

Yeah but the cicadas this season are attempting to take over my pear tree. I don’t want them to lay eggs on the branches and tunnel underneath this particular tree because it is healthier this year and starting to bear fruit 😢
But here's the question that has me curious: can enough overlapping populations of assorted singing insects interfere in technology signaling?
Why do they stay underground so long? What purpose does it serve.
