Have you ever stood in a forest and heard a sound so loud it felt like the earth itself was humming? That’s the magic of a cicada swarm, a natural phenomenon that’s both awe-inspiring and a little eerie. Right now, across the Eastern United States, something extraordinary is happening: Brood XIV, one of the largest groups of periodical cicadas, is emerging from the ground for the first time since 2008. After 17 years spent burrowing beneath the soil, these insects are climbing into the daylight, filling the air with their unmistakable chorus. It’s a rare event that feels like nature’s own rock concert, and it’s one you won’t want to miss.
The Cicada Comeback: A 17-Year Cycle
Imagine waiting nearly two decades for your moment in the sun. That’s exactly what periodical cicadas do. These fascinating creatures, unique to eastern North America, spend most of their lives underground as nymphs, sipping sap from tree roots. Then, in a synchronized spectacle, they emerge en masse, molt into winged adults, and get to work finding a mate. Brood XIV, currently making its grand entrance, is one of the largest of these groups, and its emergence is a big deal for scientists and nature lovers alike.
What makes this event so special? It’s not just the sheer number of cicadas—sometimes up to a million per acre—but the precision of their timing. Every 17 years, like clockwork, they surface when soil temperatures hit around 64 degrees Fahrenheit. This year, that’s happening from April in southern states like Georgia to June in northern areas like New York. It’s a fleeting show, though. Once above ground, these cicadas have just a few weeks to mate, lay eggs, and die, leaving the next generation to start the cycle all over again.
The synchronized emergence of cicadas is one of nature’s most remarkable feats, showcasing the beauty of evolutionary timing.

Why Brood XIV Matters
Brood XIV isn’t just another group of bugs. Scientists call it a keystone brood, meaning it plays a pivotal role in the evolution of other cicada groups. Some researchers believe that nearly all other 17-year broods in North America may have originated from Brood XIV through rare events called four-year jumps. These are moments when cicadas emerge four years early or late, creating new broods with slightly different schedules. It’s like nature hitting the shuffle button on its playlist.
This brood’s influence stretches across a wide region, from Tennessee’s rolling hills to Ohio’s forests and even pockets of Cape Cod. But here’s the catch: not every sighting is what it seems. Some cicadas, known as stragglers, pop up a year or two off-schedule, which can throw off researchers trying to map Brood XIV’s true range. Then there’s shadow brooding, where smaller groups emerge out of sync with the main brood. These quirks make it tricky to pin down exactly where Brood XIV is thriving—or declining.
- Geographic Spread: Brood XIV appears in states like Georgia, Tennessee, Kentucky, Ohio, Pennsylvania, and New York.
- Unique Challenges: Stragglers and shadow brooding complicate efforts to track this brood accurately.
- Scientific Importance: Understanding Brood XIV helps researchers study cicada evolution and brood interactions.
The Cicada Life Cycle: A Marvel of Nature
Let’s break down the life of a periodical cicada—it’s a wild ride. After 17 years underground, these insects wait for the perfect moment to emerge. Soil temperature is their cue, and once it hits that magic 64-degree mark, they tunnel to the surface. From there, they climb trees, shed their nymph exoskeletons, and transform into winged adults. It’s a bit like a teenager finally leaving home, except with wings and a mission to sing.
Once they’ve molted, the males start their iconic mating calls—think of it as nature’s loudest love song. Females respond, mating happens, and the females lay eggs in tree branches. Six to ten weeks later, tiny nymphs hatch, drop to the ground, and burrow back into the soil to start the 17-year cycle anew. It’s a process that’s both brutal and beautiful, with the adults living just long enough to ensure the next generation.
Cicadas remind us that timing is everything in nature. Their brief time above ground is a testament to life’s urgency.
A Natural Defense: Predator Satiation
Ever wonder how cicadas survive when they’re so loud and, frankly, kind of clumsy? The answer lies in a clever strategy called predator satiation. With millions of cicadas emerging at once, predators like birds, squirrels, and even your curious dog can’t possibly eat them all. There are just too many. This overwhelming abundance ensures enough cicadas survive to mate and keep the species going. It’s like throwing a buffet so big that no one can clear the table.
In some areas, researchers estimate cicada densities can reach a staggering one million per acre. That’s a lot of bugs! But this isn’t just about numbers—it’s about survival. Predators get their fill, and the cicadas still come out on top. I’ve always found this strategy fascinating; it’s like nature’s way of saying, “Go big or go home.”
| Region | Estimated Cicada Density | Key Observation Areas |
| Tennessee | Up to 1M per acre | Townsend |
| North Carolina | High density | Statewide reports |
| Ohio | Moderate to high | Clermont County, Miamiville |
How You Can Get Involved
Here’s where things get exciting: you can play a role in this natural spectacle. Scientists are calling on citizen scientists to help track Brood XIV’s emergence. By using apps like iNaturalist or Cicada Safari, anyone can log sightings, adding valuable data to research efforts. In places like Townsend, Tennessee, where 174 confirmed reports have already rolled in, everyday people are helping map this rare event.
Why does this matter? Accurate data helps researchers understand Brood XIV’s range, health, and interactions with other broods. Plus, let’s be honest—it’s pretty cool to contribute to science while witnessing a once-in-17-years event. If you’re in an affected state, grab your phone, snap some pics, and join the effort. Just don’t be surprised if you find yourself humming along with the cicadas.

Are Cicadas Dangerous?
Spoiler alert: cicadas are about as threatening as a loud neighbor. They don’t bite, sting, or carry diseases, so there’s no need to panic when you see them. The only potential downside? Young trees might take a hit during egg-laying, as females cut slits in branches to deposit their eggs. If you’ve got saplings, a bit of protective netting can go a long way.
Unlike pests that wreak havoc, cicadas are more of a temporary nuisance. Their brief time above ground is focused on mating, not munching on your garden. In fact, their presence can benefit ecosystems by aerating soil and providing food for wildlife. So, maybe think of them as nature’s short-term guests rather than invaders.
Where to Spot the Swarm
Curious where to catch this buzzing show? Brood XIV is popping up across a wide swath of the Eastern US. Tennessee, especially around Townsend, is a hotspot, with North Carolina and parts of Ohio like Clermont County and Miamiville also reporting heavy activity. If you’re in Georgia, Kentucky, or even New York, keep your eyes peeled through June as the emergence peaks.
Some areas, like Cape Cod and Long Island, have smaller, disjunct populations, but scientists warn these groups might be shrinking. If you’re lucky enough to live in a cicada zone, step outside and listen. That deafening hum is your clue that Brood XIV is in town. Personally, I think there’s something magical about standing in the middle of it all, surrounded by nature’s chorus.
Witnessing a cicada emergence is like stepping into a moment of raw, untamed nature.

The Bigger Picture: Why Cicadas Fascinate Us
Cicadas are more than just noisy insects. They’re a reminder of how interconnected our world is. Their emergence influences ecosystems, from the birds that feast on them to the soil they aerate. Plus, their 17-year cycle feels almost poetic—like a long, slow buildup to a fleeting moment of glory. Maybe there’s a lesson in there about patience, timing, or just embracing the moment when it comes.
I’ve always thought cicadas are a bit like life’s underdogs. They spend years out of sight, doing the hard work underground, only to burst onto the scene for a brief, glorious performance. It’s hard not to admire that kind of dedication. And with Brood XIV, we get a front-row seat to one of nature’s most unique shows.
