The World Cup Cicada, Chremistica ribhoi

Filed under: Chremistica | Cryptotympanini | India | Periodical | Sudhanya Hajong — Tags: — Dan @ 1:01 am

Update: a reminder that the World Cup Cicada will be back in 2022 (along with the World Cup)!

Chremistica ribhoi Hajong and Yaakop 2013 is a cicada that lives in the Ri-Boi district of India. C. ribhoi is known as the World Cup cicada because it emerges every four years in synch with the World Cup association football (soccer) tournament.

C. ribhoi is known locally as Niangtasar. It only lives in a very small area: Saiden village (25°51’37.1″N 91°51’16.3″E) and Lailad/Nongkhyllem Wildlife Sanctuary (25°55’09.7″N 91°46’25.0″E) situated on the northern part of the state of Meghalaya. The cicada can be identified by the presence of two white spots on either side of the anterior abdominal segment.

Researcher Sudhanya Hajong is gearing up to study these cicadas since this is the year they will emerge. Ri-Boi area locals use these cicadas as a food source and fish bait. These cicadas are threatened by deforestation (cutting down forests for agricultural purposes). Sudhanya plans to educate locals about conserving them and protecting their habitat.

Fiji 8-year periodical Nanai aka Raiateana knowlesi

Filed under: Cryptotympanini | Fiji | Periodical | Raiateana — Dan @ 1:25 am

Fiji $100 note

Update (11/4/2017): from Facebook, it looks like folks are finding them. Here’s an image.

Update (9/13/2017): the Nanai have begun to emerge! This cicada last emerged in 2009 in Nadroga-Navosa and Serua Provinces, and now again emerge in 2017. People in Fuji will be able to report sightings to nanai-tracker.herokuapp.com.

Notes from Chris Simon:

Early this morning I got the first Reports of the 8-year periodical Nanai emerging in Navosa, Fiji! Some people in that area had them for dinner.

This confirms earlier reports of the eight-year periodicity. There was some uncertainty because the original specimens were dated (1906) a year later than they would be if on the current 8-year schedule.

Duffels and Ewart (1988, The Cicadas of the Fiji, Samoa, and Tonga Islands, their taxonomy and Biogeograohy) noted that “Until recently the present species is only known from three males collected in “Fijii” in 1906 by C. Knowles.” Duffels was not able to describe them when he first saw the specimens because they were missing the male genitalia. After obtaining, “a series of females and two males” from Dick Watling and Andrew Laurie in 1986, Duffels was able to assign it to the genus Raiateana. There is one other species of Raiateana in Fiji, R. kuruduadua (two subspecies in Fiji and one in Samoa) but it is not periodical as far as we know.

You might be familiar with American periodical cicadas (Magicicada) and the World-cup synchronized Chremistica ribhoi of India, but Fiji has a periodical cicada too: the 8-year periodical Nanai cicada aka Raiateana knowlesi.

It also appears on Fiji’s $100 note.

There’s even a local legend about the cicada.

Avoid “Locust Loco”

Filed under: Folklore | Magicicada | Periodical — Dan @ 4:39 pm

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.

Brood VI 17-Year Cicadas Due in Spring of 2017

Filed under: Brood VI | Magicicada | Periodical — Dan @ 1:01 am

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….

BROOD VI

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.

Reading a 97 year old cicada news article

Filed under: Magicicada | Periodical — Dan @ 5:02 am

Locust

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? Report flagging and egg nests.

Filed under: Community Science | Magicicada | Periodical — Dan @ 1:01 am

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:

My 2016 Brood V Experience

Filed under: Brood V | John Cooley | Magicicada | Matt Berger | Periodical — Tags: , , — Dan @ 11:20 am

Magicicada exuvia on an oak leaf_sm
Many exuvia clinging to oak leaves. Core Arboretum, WVU.

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:

  • A junk computer. A decrepit laptop that I won’t care if it gets stolen.
  • A video camera.
  • A device for measuring sound level (decibels).
  • A notepad and pen (because technology fails).
  • Butterfly pavilions, which are these expandable enclosures for holding and observing insects.
  • Containers for holding dead specimens, and silica gel to keep them dry. Note: before you collect, make sure it is legal in the location you plan to collect. Collecting wildlife from National Parks is illegal. Collecting cicadas from a Hampton Inn parking lot is usually okay.
  • Suntan lotion and Bug Spray. I like insects, but ticks and mosquitos can turn cicada observation into a nightmare. Many researchers wear pyrethrum treated clothes (yes, bad for cats).
  • A flashlight.
  • Cicada Mania pins for folks I meet along the way.

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 (formerly Magicicada.org) 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.

Magicicada white eyes
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.

Maryland

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.

Jim Thorpe Pennsylvania Magicicada Emergence

Filed under: Brood V | Magicicada | Periodical — Tags: — Dan @ 9:12 pm

There was an unexpected* emergence of periodical cicadas in Jim Thorpe, Pennsylvania this spring. Experts believe it is a disjunct brood related to Brood XIV. Brood XIV is found in the area, according to entomologist and Pennsylvania-based periodical cicada mapper Marten Edwards, but perhaps not in the exact same specific locations. Brood II is also in the area but on the other side of the mountain. Although this group of cicadas emerged the same year as Brood V, it probably is not related (genetically & evolutionary), but that is TBD.

The terrain of the Jim Thorpe area is comprised of mountains & valleys belonging to the Appalachian Mountain system of the Eastern United States. I observed cicadas on mountainsides and in lower valley areas. They seemed most plentiful and gregarious on the edges of the forest, preferring small, young maple trees where they gathered, sang, paired off, mated and died. Although their numbers were lesser deep in the woods, I did find exit holes and exuvia there. The most interesting discovery was finding a fully sclerotized, but dead, adult cicada within an overturned teacup left in the shade of an old tree. I discovered a few “cicada chimneys”, vertical structures made of soil surrounding exit holes, under pine trees where the cicadas seemed to need to extra hight to get above the thick layer of pine needles that littered the forest floor.

The best populations seemed to be along the Lehigh Gorge Trail from its entrance on Main Street to the Lehigh Gorge, and north, up the mountain the Lehigh Gorge Trail circumscribes, all the way to Lehigh Gorge Drive. The trees along Route 903, starting at Old Pipeline Road and heading south, were loaded with active cicadas — so many, that it was hard to avoid their flying bodies as I drove towards downtown Jim Thorpe.

If you want to see them, go this weekend (June 24-26). They were plentiful in the Lehigh Gorge area:
Lehigh Gorge

The population seems to be entirely made up of Magicicada septendecim. No Magicicada cassini or septendecula were found (so far).

I found a scan of a news paper from 1880 (The Carbon advocate., March 06, 1880, Lehighton, Pa.) that mentions that “locusts” would emerge in the area in the summer. “Locust” is, of course, a common misnomer for cicada, the Carbon Advocate was the paper for the Mauch Chunk (Jim Thorpe) area, and 1880 was 8 x 17 years ago:

Brood V 17-Year Cicadas Due in Spring of 2016

Filed under: Brood V | Magicicada | Periodical — Dan @ 7:00 pm

Brood V will next emerge in 2033.

This page was last updated in 2016.

Brood VBrood V (5) 17-year cicadas have emerged, this spring of 2016, in Maryland, New York, Ohio, Pennsylvania, Virginia & West Virginia.

Latest Updates:
(7/4/16): It’s a wrap! I’m sure there are some periodical cicadas hanging on out there, but for the most part, the emergence should be over. I hope you had fun.

(6/26/16): By now you should see (and hear) sharp declines in cicada populations. They’ll be gone in most places by July 4th. You should start to see Flagging of tree limbs where the cicadas lay their eggs. This is a natural part of the process.

New: Use our checklist to keep track of your Brood V experience!

Gene Kritsky has updated his book “In Your Backyard: Periodical Cicadas“. It is available for the low price of $4.99 for Kindle and Kindle readers. Totally worth it.

About Brood V:

The cicada species that will emerge are Magicicada cassinii (Fisher, 1852), Magicicada septendecim (Linnaeus, 1758), and Magicicada septendecula Alexander and Moore, 1962. These periodical cicadas have a 17-year life cycle. The last time they emerged was 1999.

When: Generally speaking, these cicadas will begin to emerge when the soil 8″ beneath the ground reaches 64 degrees Fahrenheit. 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.

Locations where they are likely to emerge:

This data comes from the Cicada Central Magicicada Database and other sources.

Although the cicadas will emerge in MD, NY, OH, PA, VA, and WV, the area is limited and patchy. No Brood V cicadas for D.C., Cincinnati, or NYC (people have asked). Their range is closer to this map (with cicadas in the orange areas):
