Cicada ManiaCicadas have three types of life cycles: annual, periodical, proto-periodical.
A nice illustration that shows the difference between Magicicada periodical cicadas & Locust grasshoppers from the April 18, 1919 edition of The Washburn Leader, Washburn, North Dakota.
Once you see them up-close, it’s clear that cicadas are not locusts. Nearly 98 years later, people still call cicadas “locusts” though.
Which cicada has the longest life cycle?
The most famous cicadas — North American periodical cicadas — typically live 17 or 13 years. These cicadas only represent about 0.2% of all cicadas, most of which live shorter lives.
Magicicada septendecim cicadas live 17 years.
Cicada life spans (life cycle length) vary from one year to as many as 21, depending on the species. Cicadas like Myopsalta crucifera and Parnkalla muelleri of Australia have one-year life cycles6. Magicicada septendecim, M. cassini and M. septendecula, of the United States, can live as long as 21 years (read What are Stragglers?).
Some life spans for well-known cicadas:
Table 3 of the paper Genome Expansion via Lineage Splitting and Genome Reduction in the Cicada Endosymbiont Hodgkinia (Campbell et al, 2015) contains a large table of cicada life cycle lengths.
Most cicadas appear on an annual basis, meaning that every year adults will appear.
It is common for many species to be Protoperiodical as well, meaning that some years will see an abundance of adults, while other years there will be a limited number of that species. Okanagana rimosa, in particular, are Protoperiodical 9.
Some species, like the Magicicada species and Chremistica ribhoi, appear on a periodic basis, meaning that after a specific number of years almost all adults of the species will emerge.
Although many cicadas have long life cycles, not many of them make it to adulthood. Nymphal mortality of Magicicada can reach 98% in the first 2 years 4. Imagine if all those cicadas made it to adulthood. 50 times more cicadas! Unfortunately, that isn’t the case.
Magicicada is just one genus of cicadas (representing about 0.2% of all species), but I have to think that most cicadas, regardless of species, will never make it to adulthood.
Short answer: about a month.
How long a cicada lives as an adult depends on the species, but the answer could be from a matter of seconds, if the cicada dies due to predation or an accident, to more than a month. Cicadas are primarily subterranean plant (mostly tree) parasites and only enter their above-ground, adult form to mate/reproduce.
A particular species of cicada, like Neotibicen tibicen tibicen, might appear to last for two or three months, because their song can be heard for that length of time, but that’s likely because they emerge over a month, not all on the same day, extending the length of time their species is present above ground.
No matter what the species, adult cicadas perish within a season or two, and do not live multiple years in their adult form, like other types of insects. They won’t try to move inside your house once winter approaches to find warmth and shelter.

I’ll cut to the chase, in terms of Brood VI, I only experienced the emergence via my web browser. I planned on visiting North Carolina but rain and car troubles stood in my way. I did travel to Wisconsin to try to find legendary populations said to exist there, but I found no cicadas. I drove routes 90, 14, 12, 23, and roads in between, but I had no luck finding them. My investigation was by no means comprehensive, but I covered as much ground as I could in the two days I was there and found no periodical cicadas.
Brood X stragglers are a different story. I missed seeing the massive Virginia/Maryland area populations, but I was able to see cicadas in Princeton, and the significant emergence in the Dublin area of Ohio.
On May 20th I visited Princeton and found exuvia (shed skins/”shells”) on a pole next to where I parked my car, which was very encouraging. I headed for the Princeton Battle Monument park, a place where I saw massive numbers of cicadas in 2004. There, in 2017, I found exuvia but no adults — from 5 to as many as 200 per tree (I counted what I could see). The park was overflowing with squirrels and birds that would love to eat cicadas — I have no doubt why no stragglers survived. Blackbirds paced the lawn five abreast, like a small army systematically hunting for insect prey. During a normal emergence periodical cicadas emerge in such great numbers that many are able to get past the armies of hungry birds and rodents (this is called predator satiation). After visiting the park, I walked many side streets and found exuvia everywhere I went — not massive piles as we see during a normal, on-schedule emergence — but at least a few on every tree.
I returned on May 27th and actually found adult cicadas in Princeton. I found dozens of Magicicada cassini and a few Magicicada septendecim. There were not enough adults to form viable choruses. I doubt a few mated. I heard a single Magicicada cassini court song, so all least they were trying.
The most interesting cicada I saw was this Magicicada cassini with a mosaic pigment mutation, which caused the unusual orange marking on its abdomen. At first, I thought it was a Magicicada septendecim, but Chris Simon confirmed that it was not.
I also drove Rt 29 from Trenton to Frenchtown, across Rt 12 to Flemington, and down Rt 31 and heard no cicada populations. I visited Sourland Mountain. I visited many of the markers on Cicadas @ UCONN (formerly Magicicada.org) but found no cicadas, and certainly no viable adult populations (no singing, not enough to perpetuate a population).
On June 10th I made it to the suburbs north of Dublin, Ohio (itself north of Columbus). There I encountered a very active periodical cicada emergence. I mostly found Magicicada cassini, but I could hear Magicicada septendecim from time to time. I have little doubt that many cicadas mated and some of their progeny will survive to appear in another 14 or 17 years.
When I’m mapping cicadas I try to stop at every rest stop and welcome center to look for cicadas. I found periodical cicada exuvia at a rest stop on Rt 70 hear Cedar Springs, Ohio. This was a nice find because I didn’t see any sightings in this area on the Cicadas @ UCONN (formerly Magicicada.org) map.
I passed through Indianapolis, IN twice on my way to and from Wisconsin. I found some exuvia on the outskirts of Ft. Harrison State Park, but nothing inside the park (weird).
Dusk is the time of day between sunset and night. Many species of Megatibicen & Neotibicen (formerly Tibicen) sing at this time. I’m not sure why they sing at this time — perhaps it helps them avoid audio competition with other singing insects, or perhaps it helps them avoid predators by calling at this specific time of the day.
If you find yourself outdoors in the eastern half of the U.S. after sunset and hear a cicada call, it is likely one of the following Megatibicen or Neotibicen species:
Megatibicen are LARGE and LOUD cicadas.
Megatibicen auletes aka the Northern Dusk Singing Cicada. This cicada can be found in these states: AL, AR, CT, DE, DC, FL, GA, IL, IN, IA, KS, KY, LA, MD, MA, MI, MS, MO, NE, NJ, NY, NC, OH, OK, PA, SC, TN, TX, VA, WV, WI. Season: July to Fall.
M. auletes Call*:
Megatibicen figuratus aka the Fall Southeastern Dusk-singing Cicada. Found in: AL, AR, FL, GA, LA, MS, NC, SC, TN, TX, VA. Season: July to Fall.

Okanagana is a genus of cicadas that share their name with the Okanagan Lake, Valley & County areas of British Columbia, Canada. As you might guess, Okanagana are common in Canada. It is likely that the genus was named in tribute to the Okanagan people.
West of the Mississippi, O. synodica synodica & O. bella are the most common species in terms of the number of states and providences they are found. O. canadensis & O. rimosa are the most common species east of the Mississippi.
Lifespans and Lifecycles:
Okanagana rimosa have a lifespan of 9 years. Okanagana synodica have a lifespan of possibly 17 to 19 years! (see Campbell et al. 10.1073/pnas.1421386112).
Okanagana rimosa also appear to be proto-periodical (source) meaning they are abundant in some years, and scarce, but not absent in others.
“Soper et al (112) showed experimentally that Okanagana rimosa had a life
cycle of 9 years, and that in the field during a 9-year period (1962 to
1970) it was extremely abundant in 4 years and scarce or absent in the
other 5. Heath (32) also studied cicadas of the genus Okanagana and
found several species that appear to be protoperiodical.”
I’m not sure, but I suppose other species of Okanagana have proto-periodical lifecycles as well. This would explain why people see Okanagana in great numbers one year, and very few in previous years.
Identification:
Okanagana are typically around between June and July, depending on the species and latitude.
Okanagana are often black, with white, beige or orange highlights on their wings and body. The black color of their exoskeletons helps them absorb warmth from the sun.
Look for four symmetrical markings on their mesonotum (back). The image at the beginning the the article highlights these markings.
One Okanagana that has atypical coloration is the O. viridis which is green. This outlier is one of the few species found in southern states.
Summer is here now, so it is time for annual species of cicadas. See which types of cicadas are in your area.
If you experienced Brood X stragglers this spring, it’s not to late report the location where you saw them to Cicadas @ UCONN (formerly Magicicada.org). In the Ohio area, send your cicada photos of Mount St. Joseph University.
Other updates can be found in the comments.
This year “precursors” to Brood X are emerging or will emerge in small to large numbers in D.C., Delaware, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, Missouri, New Jersey, New York (Long Island), North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia, and West Virginia. Cicadas @ UCONN has the most up-to-date map from Brood X.
Note: because of the significant number of cicadas emerging ahead of time, this might be an acceleration event. Periodical cicada accelerations occur when a significant group of an established brood emerge in years ahead of the main brood, and sometimes the accelerated group is able to reproduce and create what is essentially a new brood. Brood VI was likely part of Brood X at one point of time1. We’ll have to see if the Brood X stragglers are able to survive predation, and reproduce in significant numbers to sustain future populations. They are certainly trying.
Some more info to impress your friends with:
These are the species you might hear/see:
Don’t panic! Less that one percent of a Brood straggles. If you had 10,000 cicadas in your yard back in 2004, you can expect a less-frightening or more manageable dozens or hundreds (okay, maybe 1,000s). 🙂
Brood VI also emerged this year in North Carolina, South Carolina and Georgia. These cicadas emerged on schedule, and are not stragglers. It is believed that Brood VI descended from Brood X through acceleration (mentioned above).
Brood VI compared to Brood X:
The data comes from Cicadas @ UCONN (formerly Magicicada.org).
Stragglers are periodical cicadas that emerge in years before or after the brood they belong to is expected to emerge. Typically 17-year periodical cicadas emerge 4 years early (see the probability chart). While stragglers might not produce enough offspring to produce future generations, straggling is something periodical cicadas do — it is hard-wired into their DNA. The 4-year interval is also typical.
Stragglers are not a new phenomenon. William T. Davis documented accelerations of cicada populations back in the 1800s, which was reported by C.L. Marlatt in the 1898 document The Periodical Cicada. An Account Of Cicada Septendecim, Its Natural Enemies And The Means Of Preventing Its Injury.
Mr. W. T. Davis records the occurrence of scattering individuals on Staten Island in both 1890 and 1892, neither of which is a Cicada year. These may have been of accelerated or retarded individuals, but possibly represent either remnants of broods or insignificant broods not hitherto recorded.
In the case of W. T. Davis’s observations, Brood II would have emerged in 1894 in Staten Island, so 1890 would have been a 4-year straggler/processor/acceleration, and 1892 a rare 2-year acceleration.
The term “straggler” throws people off because most people are familiar with the definition of straggler that means “something that falls behind the main group”. These cicadas are clearly ahead of the main group, not falling behind. Straggle can also mean “to wander from the direct course or way” (Merriam-Webster), “to trail off from others of its kind” (Merriam-Webster). In terms of cicadas, scientists and naturalists have been using the term “straggler” for over a century, so it has stuck around. For now, don’t worry about the term, just know that it means periodical cicadas that are not emerging on schedule.
More information on stragglers and accelerations.
Dr. Gene Kritsky, in this recent article, is quoted as saying “[c]limate changes are behind the premature debut”. Visit Gene’s website.
It makes sense that climate variations would trigger periodical cicadas to emerge ahead of time. Periodical cicadas take cues from the seasonal cycles of their host trees. An unusual climate event, like a hot fall or winter, might cause trees to signal cicadas that additional years have passed, and cause them to shift to emerge early. In the paper, How 17-year cicadas keep track of time, Richard Karban was able to show that you can speed up the time it takes for a periodical cicada to emerge by artificially altering the seasonal cycles of their host trees2. It’s likely that the Brood X stragglers emerging now were set on their path to emerging 4 years early not this year or the last, but many years ago.
Metropolitan areas like Washington D.C., called “HEAT ISLANDS” (read this article), can often be much hotter than surrounding rural areas due to human activity. The effects of living within a heat island may have disrupted the seasonal cycles of the cicadas’ host trees, and therefore the cicadas themselves. Localized climate change will be considered as a contributing factor to their early emergence. If we find considerably fewer stragglers in rural areas than city areas, then we could draw a conclusion that local climates are contributing to straggling.
Other than climate (in the long term), weather (in the short term), and a natural propensity to straggle or accelerate, population density is another reason why cicadas will straggle. If there is a high density of them underground, vying for limited resources, some might emerge a year or so before or after the main Brood.

Brood VI will next emerge in 2034.
This page was last updated in 2017.
Final Update: I traveled to Wisconsin last week and spent a few days looking for cicadas in the southern part of the state (Madison, Baraboo, Janesville, Cedar Bluff, Dodgeville) but unfortunately I did not see or hear any. :(. So far this year though, Brood VI was spotted in GA, NC, SC, OK, OH and perhaps NY….
Previous updates can be found in the comments.
Brood VI (6) 17-year cicadas (“locusts”) will emerge in the spring of 2017. The main group will emerge in South Carolina, North Carolina and Georgia. Other lesser groups should emerge in Ohio & Wisconsin. And possibly other states/locations as well.
About Brood VI:
The cicada species that will emerge are Magicicada septendecim1, Magicicada septendecula1, and possibly Magicicada cassini2. These periodical cicadas have a 17-year life cycle. The last time they emerged was 2000.
When: Generally speaking, these cicadas will begin to emerge when the soil 8" beneath the ground reaches 64 degrees Fahrenheit 3. A nice, warm rain will often trigger an emergence. So, definitely May, but something might happen in April if we have a particularly hot spring.
Report a sighting: If you see or heard cicadas, please report them to Cicadas @ UCONN (formerly Magicicada.org). This helps researchers map the location of the cicadas.

I was looking through old newspapers for articles about periodical cicadas. I found an article in the Taiban Valley News from April of 1919, titled “17-Year Locust” Due This Year1. The Taiban Valley news was published out of New Mexico, which does not experience periodical cicadas aka “17-year locusts”, so I guess the story was supplied to its readers as a curiosity — just something oddball/interesting to read. The text of the article was supplied by the U.S. Department of Agriculture (possibly C.L. Marlatt himself), and the main image of the article is an illustration that appeared previously in U.S. Department of Agriculture documents and is attributable to a Miss L. Sullivan2.
“Locusts”
97 years ago people called periodical cicadas “locusts”, just as they do today. I quote, “It has been so long miscalled by the name of locust, however, that there is no hope of divesting it of that incorrect appellation”. “No hope”! Even today, about half the people I meet call them “locusts”.
Human lifespans were a lot shorter 97 years ago
The next fact — and this startled me — is how short the average human lifespan was 97 years ago. I quote: “The fact that it appears in countless numbers one year, then is not seen again for half the average lifetime of human beings and then suddenly appears again in countless numbers”.
Half the average lifespan of human beings? Back in 1919 the average life expectancy was just 55. At most a person could expect to witness 3 emergences back then, and since babies and toddlers really don’t remember things, 2 times makes sense. Today (2016) life expectancy is around 79 years in the U.S., which means the average person will only get to see 4. I’ve seen 9, but I travel around.
Vermont still had periodical cicadas:
Back in 1919, Vermont still had periodical cicadas: “with some Isolated colonies as far northeast as upper Vermont”. Since then, they must have gone extinct.
Brood 18?
The article talks about Brood 18 emerging in the same year as Brood 10 (note, the article does not use Roman numerals). I believe the Brood 18 the article they refer to is what we now call Brood 19 (XIX) today. The article describes Brood 18 as having a 13-year life cycle, and occurring in Alabama, Georgia, North Carolina, South Carolina and Tennessee. The only brood that matches that is Brood XIX (see the map).
If it is indeed Brood XIX, the article is likely incorrect about the coincidence of Brood XIX and X emerging in 1919. While Brood X definitely emerged in 1919, Brood XIX would emerge in the following year 2020. Interestingly enough, the now extinct Brood XI emerged in 2020 (in Connecticut).
The rest of the article is less remarkable, but still a fun read for “the most interesting insect in the world”.
Update (8/26/2016):
David Marshall of the University of Connecticut pointed out a map of the Brood XVIII that was indeed set for emergence in 1919, which is likely what the writes of the article were citing. David points out though that this Brood XVIII was likely comprised of one-year-early emergences (stragglers) of Brood XIX, rather than an actual unique brood.

Got flagging? Flagging happens when tree branches wilt or die due to cicada egg laying, resulting in bunches of brown leaves. Don’t worry, this will not cause trees to die, unless they are small and weak trees. Flagging can actually do a tree a favor, by removing its weakest branches.
Some video of cicada flagging:
A photo of flagging:

My plan was to check out Maryland first, then head to West Virginia for a few days, and then Ohio. If weather, time and patience allowed, Virginia and Long Island, New York. Like all my periodical cicada trips I start by consulting the map on Cicadas @ UCONN (formerly Magicicada.org) to see where folks are finding cicadas. I also consult with the folks who study periodical cicadas professionally to discover their favorite hot spots and any locations of particular scientific interest. This year, the interesting spot was north-western Maryland — more on that later.
Generally speaking, you’ll see a lot of pin-drops for Magicicada cassini on the map. This is because you can hear them while driving at 70mph. You often have to stop your car and turn off the engine to hear the other species, so even though there’s lots of M. cassini on the map, there’s probably just as much M. septendecim. Generally speaking, my mapping methodology works like this: I stop and take notes when I can (usually at rest stops, parks or when I’m staying in a particular town — see Morgantown & Athens later in the article) and this is when I’ll hear M. septendecim & M. septendecula, but when I’m driving interstate highways at high speeds (with a parade of angry drivers who would rather tailgate me that use the left lane to go around me) I can only take data points for M. cassini.
What do I bring with me on a seven-day cicada road trip? Aside from clothes, road food, smartphone, and my AAA card, I bring equipment to aide my study of cicadas:
What I don’t bring but should is one of John Cooley’s Cicada O Matic GPS Dataloggers. I have to make observations by hand.
Other than that, I follow the typical Power Vacation rules.
Maryland Part 1:
The first town I hit was Accident, Maryland (great name). There were sightings on the Cicadas @ UCONN map, and the name of the town was awesome, so I wanted to check it out. Unfortunately, I didn’t observe any cicadas there.
Route 68, West Virginia
Traveling west along Route 68, about half-way between the center of Bruceton Mills and Coopers Rock State Forest I started to hear pockets of M. cassini. I stopped at Coopers Rock, and at first, I was disappointed: I didn’t hear any cicadas from my car. Once I stopped my car and turned off the engine I could hear them: M. septendecim with their spooky sci-fi UFO chorus in the distance. It became obvious that the park had a healthy population of M. septendecim, with a smattering of M. cassini as well.
Morgantown, WV
Next, I arrived at Morgantown, WV. Some twitter friends had been posting cicada photos from there, so I thought it would be a good location to set up base and make observations for a few days. The hotel I chose had an excellent population of M. septedecim and cassini around it; so much so that the staff couldn’t keep up with unwanted cicada guests that littered their doorway, trampled by oblivious human guests.
My first day there I walked around the West Virginia University campus near the hospital, stadium & iHop. The sky was overcast and it was getting late in the afternoon, but it was clear that the campus and town had an abundance of periodical cicadas, and that I made a good choice in setting up camp there. At night, in my hotel parking lot, I was able to watch cicadas emerge as nymphs as transform into adults, which is always a highlight of an emergence for me.
WVU Core Arboretum
Core Arboretum is a large botanical garden devoted to trees (“arbor”) on the WVU campus. It was an excellent place to observe cicadas. I was able to observe all three species, the tiny but LOUD M. cassini, the larger & relatively docile M. septendecim, and the rarest of the species M. septendecula. Finding M. septendecula so early in my trip was a treat. Their clockwork/tambourine sound (at least that’s what I think they sound like) gave them away.
I met entomologists Matt Berger, who has contributed many cicada photos to this site over the years, and his colleague HereBeSpiders11 (twitter name). Awesome people. I met Zachariah Fowler, the director of the arboretum as well. Another awesome person.
A white-eyed Magicicada septendecim.
I was able to check off many of my cicada checklist items in Morgantown: I found a white-eyed cicada, I saw & heard all three species, and more.
Leaving West Virginia, Entering Ohio
M. cassini were plentiful along route 79 and 50 headed west towards Athens, Ohio. Along the way, I made a few stops and heard & observed some M. septendecim as well.
Athens, Ohio
Athens was another good location to stay and observe cicadas. The parks in the surrounding area had excellent cicada populations, and I had a rare chance to meet John Cooley of Cicadas @ UCONN (formerly Magicicada.org).
My first day in Athens I spent at Dow Lake in Strouds Run State Park. There I met John Cooley who was there showing a German film crew the particulars of cicada behavior. Dow Lake had a healthy mix of LOUD M. cassini and M. septendecim, but the cassini definitely dominated. The highlight for me was not a cicada, but spotting a rat snake climbing down from an acacia tree where it was no-doubt snacking on cicadas.
Sells Park in Athens was a nice place to hear VERY LOUD M. cassini choruses, well into the high 80-90db mark. So loud that I limited my time there, and left after an hour.
Hocking Hills
Hocking Hills is an amazing park north of Athens than features a spectacular above-ground cave and many acres of forest filled with cicadas. Hocking Hills had a good population of all three species, and M. septendecula were unusually easy to find. They seem to have preferred areas where deciduous trees blended with evergreens, at least in the locations I found.
Vinton Furnace Experimental Forest
A Magicicada cassini chorus from the Experimental Forest:
A Magicicada chorus with audible M. septendecula from the Experimental Forest:
Vinton Furnace Experimental Forest is a forest curated to include as much biological diversity as possible. All three periodical cicada species make up part of that diversity. M. septendcula choruses were very easy to find. The forest was thrilling to visit — aside from the biting deer flies, it was exhilarating to see or hear so many species of insects, birds, and plants in one place. Also, thrilling were the winding one-lane dirt roads; I almost died a few times thanks to wild drivers out for a pretend Finland Rally race.
Back to Maryland
After an overnight stop back in Morgantown, WV, I headed back to Maryland to prove (or disprove) that periodical cicadas were there, and if I did find them, the extent of their population. It is important to show the limits of their population as researchers (John Cooley in particular) are interested in demonstrating that the Brood V population in Ohio, Pennsylvania, West Virginia & Maryland is distinct from the population in Virginia.
I’m happy to report that I did find periodical cicadas in Maryland. The populations were mostly the relatively quieter M. septendecim — the type you really have to stop the car & turn off the engine to be certain they’re there. I did find M. cassini as well, but M. septendecim dominated. The adorably named Friendsville and Selbysport had good populations, as did the hill above the Youghiogheny river overlook rest stop on I68. South of this area, I did not hear or see cicadas on Bear Creek Road, Rt 42, Rt 219 or Rt 495. It is possible there are pockets of cicadas deep in the woods and out of earshot in those areas, but it is clear there was no great population of periodical cicadas in those areas if any at all. I spoke to a chainsaw bear sculptor in Bittinger, which is not far from where the Appalachian Plateau ends & the Ridge and Valley area starts. I showed him a photo of a periodical cicada. He said he had never seen them in his life, and nor did he see them in Accident where he went to church. He did hear about them on the news, so he was aware of them.
Pennsylvania, and home
After collecting cicada data and buying a chainsaw bear, I headed north into Pennsylvania. I stopped at a rest stop, enjoyed the last I would hear of Brood V, and headed back home.
