Lynn Faust, author of the book Fireflies, Glow-worms, and Lightning Bugs, wrote us in early May concerned that the wild hogs in her area had rooted up and eaten Brood XIV cicadas about to emerge. Hogs are omnivores and are excellent at finding food buried underground, so her assumption makes sense.
She told us that the Turkey Camp on Greasy Creek had hundreds of intact pre and post emergence cicada turrets in 2008, with lots of chorusing. However, in 2025, there were no intact cicada turrets where the hogs plowed up the ground. There were plenty of fragments of turrets, but no adult cicadas or their shells (shed skins).
You can see the hob rooting in Lynn’s photos:
Any impacts to cicada populations, like hog rooting, is interesting to people who study cicadas.
Good news!
Fortunately some cicadas survived, in the hog-plowed areas, and there was no impact in the areas where the hogs did not plow up the ground.
News from Lynn:
Today 10 days later (May 19, 2025) than first visit, completely different!
All previous locations still singing loudly by the 1000s, millions?
Greasy Creek drainage was also singing loudly!
In the plowed up areas, there remained no cicada skins and no evidence and broken mud towers.
BUT, away from the roads much of the forest was intact and apparently plenty made it up into the treetops and they are singing and courting mightily now.
So I wanted you to know the happy ending. Those hogs won a good cicada buffet, but Cicada Brood 14 won the season!
Here are some of Lynn’s photos. All photos in the post are copyright of Lynn Faust.
Magicicada periodical cicadas often emerge earlier or later than expected. This phenomenon is called straggling, and the individual cicadas that emerged earlier or later are called stragglers. Magicicada are presumed to straggle for a number of reasons including subterranean overcrowding and the effects of urban heat islands on subterranean environments (a recent phenomenon). Evolutionarily speaking, it is a mechanism that allows them to break away from their original brood and form a new one. Right now on the homepage of the UCONN Cicada site they have a good story about how Brood XIV connects to Brood X, which connects to VI, which connects to II.
Stragglers, in the past, were observed and documented (MORRIS,J. G. 1870. Seventeen-year locust two years too late. Amer. Ent., 2: 304.) but it is much easier to do so today thanks to apps like iNaturalist, Cicada Safari, and mobile phones and social media in general.
So, where are we observing stragglers in 2025?
Down in the Baton Rouge area of Louisiana, Brood XXII is emerging 2 years early (iNaturalist Map). Brood XXII typically has a 13-year lifecycle.
There are many Brood X stragglers emerging in the Washington D.C. area (iNaturalist Map).
Brood I stragglers are appearing in the Roanoke, Virginia area emerging four years early. (iNaturalist map).
There are a handful of Brood X stragglers in the Princeton, NJ area. (iNaturalist Map).
And here’s a map that plots all the Broods, courtesy of Cicadas @ UCONN:
Two notes:
1) The general public does not like the term stragglers when applied to cicadas that emerge early, because straggling generally means to be late, not early. Marlatt referred to them as precursors (Marlatt, 1989). You can use that term if you like.
2) People called cicadas locusts in the recent past. Scientifically speaking and in modern times, a locust is a grasshopper. Cicadas and grasshoppers are very different insects, but they can emerge in large numbers and do some damage to plants (cicadas cause flagging on trees, while locusts eat everything), hence the confusion.
How rare are Magicicadas cicadas with white or blue eyes?
Do we include yellowish-white/cream-colored eyes? Gray eyes?
“One in a million!”
“One in 100,000?”
“One in 1000”?
Let’s look at some data. Since its beginning, as of June 19th, 2024, iNaturalist has had 27,294 Research Grade Magicicada sightings, and 136 Research Grade “Magicicada eye color=blue/white” cicadas. So, in the iNaturalist data set, one in 201 Magicicada have white or blue eyes.
The number of white/blue eyed Magicicada is without a doubt more than one in 201, but not one in a million. Personally, I’ve found at least one cicada with white or blue eyes per emergence. My guess is the number is closer to one in 10,000.
But don’t tell anyone who is excited about a one in a million find. Let them have their fun and happiness. 🙂
As I write this, the Brood XIX emergence is all but over, and Brood XIII has about two weeks left to go.
So what’s next? Well, I’ll tell you.
Upload your photos to iNaturalist and the Cicada Safari app
You can help cicada researchers by uploading your photos to iNaturalist or the Cicada Safari app.
iNaturalist is excellent for all animals — plus plants and fungi — not just cicadas. You will find yourself using it all year long. Cicada Safari is specifically for cicadas.
Learn about Annual species of cicadas
There are more to cicadas that just Periodical cicadas.
Cicadas exist on every continent except for Antarctica, and in every State in the U.S. except for Hawaii and Alaska!
Saving cicada skins (molts/shells) and wings is easy. Just keep them dry.
Preserving Periodical cicadas can be challenging because their eye colors fade and because they’re fatty and smell.
If you want to preserve eye colors, keeping them in alcohol seems to work best.
Some people dip them in acetone to mitigate the smell from decaying fat, but I’ve never tried it.
Otherwise, keep them dry and in a cedar box. I use silica gel packs to keep them dry. Cedar repels small insects that will eat your cicada collection. Moth balls work as well to keep tiny insects away from your collection.
If you want to pin your cicadas, so the wings are spread out, you have to do it while the cicadas are still moist. Plenty of places have supplies, like Carolina Biological Supply. I’ve softened hard cicadas by placing them in Tupperware/Rubbermaid containers with moist paper towels and a moth ball to prevent mold.
Make a scrapbook of your cicada memories
Make a scrapbook or photo album of your cicada memories.
This is something I do every year, though I tend to mix it up with non-cicada photos as well.
It’s a Wrap! Periodical cicada Brood XIV (14) emerged in the spring of 2025 in Georgia, Kentucky, Indiana, Massachusetts, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia. The last time this brood emerged was in 2008. The emergence has begun in states highlighted in green. Just New Jersey appears to be a bust.
Here’s what the emergence looked like over time, across the U.S. (includes a sprinkling of straggler data):
Usually beginning in May and ending in late June. These cicadas emerge approximately when the soil 8″ beneath the ground reaches approximately 64 degrees Fahrenheit. Above ground temperatures in the 70’s-80’s help warm the soil to that point. A warm rain will often trigger an emergence.
Other tips: these cicadas will emerge after the trees have grown leaves, and, according to my own observation, around the same time Iris flowers bloom.

*City data comes from May 2008 and June 2008 blog comments. County locations are historical and may no-longer be accurate.
Experts (Gaye Williams, State Entomologist of Maryland, John Cooley of UCONN) have confirmed that there will be no Brood XIV cicadas for Maryland. That said, there will be some stragglers from Brood X. You can look for reports of stragglers using this iNaturalist map.
More Maps and Location Tips!
Cicadas @ UCONN has the most up to date maps. Zoom in and look for the images of cicadas.
* Although county locations may no longer be accurate, I like to keep them on the page in case someone discovers a small, secret or unknown population of these cicadas. People might be disappointed, but we want to know for sure that the cicadas are (or are not) thriving in historical locations. This is the cicada researcher’s dilemma: either focus on the guaranteed/sure shot locations for the general public to enjoy, or include the obscure, relic locations so we do not miss out on rare cicada sightings. Cicadas @ UCONN talks about the relationship between the different broods — Brood XIV and Brood X are closely related geographically and genetically. You might find a Brood X straggler emerging 4 years late, and mistake it for Brood XIV. If a large number (large enough to sustain future emergences) of Brood X makes the 4-year “JUMP” to be in synch with Brood XIV, they technically become Brood XIV (and the reverse is true).
Got Massospora?
Have you seen any cicadas with Massospora infections. Professor Matt Kasson of WVU wants your Massospora-infected Magicicada cassini and septendecula cicadas (but not septendecim). Email mtkasson@mail.wvu.edu if you have one to share!
People ask, “Can periodical cicada singing damage hearing”? It all depends on how long you expose yourself to their song, and how close your ears are to the insect. Invest in some quality ear plugs if you are concerned. Consult a medical professional, of course. Get a Sound Level Meter.
Periodical cicada choruses are often in the 80–85db range, which the CDC says “You may feel very annoyed” and “Damage to hearing possible after 2 hours of exposure”:
If you spend a long time outside during a chorus, your ears will probably ring for hours after. That is my personal experience.
Placed directly on a microphone, I have observed periodical cicadas get as loud as 111.4db. According to the CDC, that is close enough to cause hearing damage in less than 2 minutes. Do not place male cicadas on your ear! Do not put your head right next to the tree branches where they’re singing.
Check out this video of Magicicada sound levels measured by an EXTECH 407730 Sound Level Meter:
How to avoid hearing them?
Stay indoors
Buy earplugs or headphones that block external sound
Avoid their peak singing times, between 10 am and 5 pm. Before 10 am and after 5 pm are also the best times to do yard work to avoid them.
I’ve exposed myself to hundreds of hours of cicada songs. I’ve also gone to hundreds of concerts and listened to a lot of rowdy music over the years. My hearing is not great, but it is probably not due to cicadas.
It is worth mentioning that only male cicadas sing. Females make noise by flicking their wings, but they are not as loud as the males. Males have organs called tymbals that vibrate creating their signature sound.
Here are illustrations and a photo of a Magicicada’s tymbals. They have one on each side of their body:
So what is the loudest cicada? According to the University of Florida Insect Book of World Records, “The African cicada, Brevisana brevis (Homoptera: Cicadidae) produces a calling song with a mean sound pressure level of 106.7 decibels at a distance of 50cm.” The loudest cicada in the United States, using the same methodology, is Diceroprocta apache (Davis) at 106.2db at 50cm.
I need to take measurements of Magicicada from 50cm to make a comparison. The measurements I’ve taken are in the midst of a large chorus with cicadas about a meter to 20 meters away, which falls in the 80-85db range; or directly on the mic, which gets into the 109-111db range. Your results may vary.
One phenomenal behavior of Magicicada periodical cicadas is they “straggle”, meaning they emerge earlier or later than the year they are expected. Typically they emerge 1 or 4 years before they’re supposed to emerge.
Brood XXIII is expected to emerge in four years in 2028, but enough are emerging in 2024 for cicada researchers like Chris Simon to take notice! She let us know about the stragglers on May 8th.
Brood XXIII is found in Arkansas, Illinois, Indiana, Kentucky, Louisiana, Mississippi, and Tennessee. This is not a perfect map (it overlaps with Brood XIX), but XXIII cicadas will show up in that area.
Arkansas: Bayou Deview Wildlife Management Area, Poinsett County, Devalls Bluff, Harrisburg, Holland Bottoms, Jacksonville, Jonesboro, Knox Co., Lake Hogue, Lake Poinsett State Park, Little Rock, and Wynne.
Illinois: Anna, Carbondale, Carterville, Chester, Clinton Lake, Marissa and Robinson.
Indiana: Harmonie State Park, Hymera, Leanne, Richland, Sullivan And Posey Counties.
Kentucky: Benton, Calvert City, Gilbertsville, Henry County, Murray, and Paducah.
Louisiana: Bastrop, Choudrant, Grayson and West Monroe.
Mississippi: Alva, Arlington, Booneville, Brandon, Clinton, Corinth, Desoto County, Florence, French Camp, Hernando, Holcomb, Houlka, Jackson, New Albany, Oxford, Potts Camp, Silver Creek, Tishomingo, and Water Valley.
Tennessee: Atoka, Benton, Cordova, Henry County, Huntingdon, Jackson, Lavinia, Leach, Lexington, McNeary County, Memphis, Paris, Savannah, and Speedwell.
Here’s a blue overlay of there Brood XXIII emerges from the UCONN map on the iNaturalist data (as of May 5th):
Surrounding the blue area on the west and east is Brood XIX and north will be Brood XIII.
Upload a tree or branch with flagging to iNaturalist, add it to the Magicicada Flagging Project, and when it asks you if the observation has “Magicicada Flagging” select “yes”.
When Magicicada cicadas lay eggs in the branches of trees (ovipositing) branches may become damaged or die which causes the leaves to turn brown. This is called flagging. Magicicadas, depending on their location, oviposit between late April through to the end of June. Flagging will appear in the weeks following ovipositing. Leaves will remain brown throughout the year.
The project works regardless of whether the organism is identified as a type of tree (oak, chestnut, etc.) or a Magicicada cicada. Most people identify trees with flagging as a “Magicicada” but I would not want to take away the option to allow people to identify a tree (oak, chestnut, etc.) over the type of cicada that did the damage.
There is a similar observation field for cicada presence set to flagging/oviposition scars, but it’s not specific to Magicicada and oviposition scars do not always accompany flagging. I do encourage you to use this observation field as well!
How can you tell if a Magicicada periodical cicada nymph is ready to molt?
Answer: look for two black spots on its back (technically the cephalothorax). They look like they are wearing aviator sunglasses pushed up on their forehead!
I do not know the official name for these spots, but they seem to be related to the pigment that turns the cicadas black after they molt. They may scare away predators that think the spots are big eyes!
Here are a few ideas for a name for them:
obscuras maculas
mutatione macularum
