Watch a Swamp Cicada shed its skin

Filed under: Neotibicen — Dan @ 6:30 am

Here’s a video I made this week. It is a Neotibicen tibicen tibicen (formerly Tibicen chloromera) shedding its skin as it enters the final phase of its development. The video is in 4K HD, but you have to fuss with the YouTube interface to see it at that resolution (good luck). Each frame represents a 30 sec time span.

Spoilers:

At 18 seconds its head pops out of its old skin.

At 27 seconds it frees its wings.

At 51 seconds it flips and unfurls its wings.

At 85 seconds it moves its wings into place.

At 100 seconds you can see pigment pulse through the cicadas mesonotum:

Annual Cicada Hunt in Manchester, New Jersey

Filed under: Elias Bonaros,Neotibicen — Dan @ 8:34 pm

Neotibicen auletes

Since 2013 I’ve met Elias Bonaros and Annette DeGiovine in Manchester, New Jersey to search for the cicada Neotibicen auletes. It has become an annual tradition.

N. auletes is the largest cicada in the Americas, they have a particularly arresting call, and are a beautiful lime green when recently molted. They are definitely worth taking the time to find.

Locating and observing cicadas in northern States can be particularly vexing because they are far less abundant, and much of their habitat has been eliminated to make way for the ever-growing, densely-packed human population. It is a treat any time we can find and observe a living cicada specimen up-close. If you’re the type who likes to travel to observe cicadas, New Jersey is not a great place to start on the east coast. Southern states, starting at North Carolina to Florida are your best bets, in terms of species diversity and abundance. If you’re a collector, be aware of local laws — for instance, collecting in Florida is completely forbidden.

This year’s adventure began around 7:15pm when I arrived at the mini-mall where Caballero’s Pizzeria is located (Manchester, NJ on Route 70). Part of the tradition is to have a few slices of pizza, and after four years the owner knows who we are. The mini-mall the pizzeria is located in is bordered on the right by a sandy-soil pine & oak forest, and in front by two small groves of tall oaks & pines. Oddly, the ground of these groves has been covered with a back mesh tarp, which completely prevents underbrush growth. This doesn’t seem to deter cicadas from emerging, bu I’m skeptical that future generations of cicadas will find the smaller plant roots they need during the early stages of life.

At 7:15pm the small and beautiful Neocicada hieroglyphica cicadas were singing from many trees in groves and forest (they would continue singing to around 9pm, well past sunset). Around 7:30pm Neotibicen linnei began to join them.

Elias and Annette arrived shortly before sunset, around 8pm, giving them time and daylight to scout the grounds for deceased adult specimens and exuvia (molted skins); oddly none were found. Neotibicen auletes calls at dusk, right after sunset. On queue multiple N. auletes began calling from the trees in the groves and forest, like a soloist overpowering the lesser vocalists and instruments around him, N. auletes are the divas of the New Jersey cicada opera.

No exuvia or dead N. auletes was found, but the many calls we heard were encouraging. Once night fell we began to search the local area for emerging nymphs and molting adults. After a long search Elias found a single female auletes molting on the side of a school. Three hours of searching only yeilded one cicada — for those who have experienced periodical cicada emergences, or those who live in areas with an abundance of annual species, a lone cicada would be very disappointing. For Elias, Annette and I, finding a lone (locally) rare cicada, was not disappointing at all.

The funniest moment of the night came when a local policeman asked us if we were hunting Pokemon! Of course we were not — we were hunting cicadas. A little harder to explain, and probably more fun.

New paper catalogs the cicadas of India, India, Bangladesh, Bhutan, Myanmar, Nepal and Sri Lanka

Filed under: India — Dan @ 6:09 am

A paper titled The cicadas (Hemiptera: Cicadidae) of India, Bangladesh, Bhutan, Myanmar, Nepal and Sri Lanka: an annotated provisional catalogue, regional checklist and bibliography was published in June of 2016 in the Biodiversity Data Journal 4: e8051. The authors of the document include, Benjamin Wills Price, Elizabeth Louise Allan, Kiran Marathe, Vivek Sarkar, Chris Simon, Krushnamegh Kunte, but I think Ben was the lead.

You can access it here: http://bdj.pensoft.net/articles.php?id=8051

Quotes from the abstract:

Background

The cicadas of the Indian subcontinent, like many other insects in the region, have remained understudied since the early part of the 20th Century, and await modern taxonomic, systematic and phylogenetic treatment. This paper presents an updated systematic catalogue of cicadas (Hemiptera: Cicadidae) from India, Bangladesh, Bhutan, Myanmar, Nepal and Sri Lanka, the first in over a century.

New information

This paper treats 281 species, including: India and Bangladesh (189 species), Bhutan (19 species), Myanmar (81 species), Nepal (46 species) and Sri Lanka (22 species). For each species all recognized junior synonyms are included with information on the type material and additional specimens where relevant.

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”.

Color the cicada and the cicada killer wasp

Filed under: Cicada Killer Wasps,Papers and Documents — Dan @ 7:42 pm

Today I was searching old news papers for cicada information, and I came across a gem from the past.

One of the papers (New-York tribune. (New York [N.Y.]) September 21, 1902, Image 43) I found features an illustration of a cicada being carried off by a cicada killer wasp. The illustration appeared in the kids section of the paper and was meant to be colored.

NY Tribune 1902

The cicada is referred to as a “Harvest Fly”, which indicates that it is a member of the genus Neotibicen (back in 1902 I think the genus was either called Cicada or Tibicen). Judging by the description of the cicada it is likely a Neotibicen tibicen tibicen aka the Swamp Cicada.

Instructions for coloring the insects:

Directions for coloring-. Body black, with a dark
green band just back of the head, and two round
white spots on the first ring- or segment of the
abdomen. The eyes, legs and antennas are green.
The veins of the wings are green near the tody,
gradually shading into black at the tips. The
wings are transparent. The wasp, which is carry
ing off a dead harvest fly, is brown-the color of
bronze. The pupa or young harvest fly in the tree
is brown also. The tree trunk is dark brown; the
grass green.

The harvest fly, or cicada, often incorrectly called
locust is usually the herald of hot weather. He
comes out in August, and the hotter the day the
more energetically he sings. He is own cousin to
the seventeen-year cicada, and it takes him two
years to reach his growth. He begins life as a
Uny egg bidden away by his mother under the
bark of sum.- tree. Who, he hatches out a tiny
grub, he begins eating Into his surroundings and
often does much damage. Soon he changes to a
pupa, and falls to the ground, i” which he imme
diately buries himself. Here he remains for two

New emoji are coming soon. A adult butterfly will be added to the list of insect emoji, which include a beetle, ant, caterpillar (aka larval butterfly) and bee. You know what is missing? A cicada.I doubt we’ll get it now that the emoji are decided by a consortium, but you never know.

Got Flagging? Report flagging and egg nests.

Filed under: Citizen 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.

Visit the Magicicada.org report page to report flagging (scroll towards the bottom of the form / only on Desktop for now).

My 2016 Brood V Experience

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

Magicicada exuvia on an oak leaf
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 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.

Here’s my own map of my journey in terms of the places I saw/heard cicadas. 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 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 3
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 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 by 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 interesting 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 Youghioghheny 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,Brood XIV,Magicicada,Periodical — 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 mountain sides 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 tea cup 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 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.

Here is a map of where I saw them. 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).

Locals were calling them “Locusts” — sometimes I forget that’s what folks call them, but of course they’re really cicadas.

Post script:

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:
