Color variations in Neotibicen tibicen tibicen

Filed under: Neotibicen | Tibicen — Tags: — Dan @ 8:25 am

Color variations in chloromera tibicen
The cicada on the Left was found in Middletown NJ, and the cicada on the Right in Metuchen, NJ. Middletown is closer to the ocean than Metuchen is, but both share a similar elevation and vegetation.

It is interesting to note the color variation found in Neotibicen tibicen tibicen aka chloromera aka Swamp Cicada aka Hunch-Back cicada.

In some areas the dorsal side of N. tibicen tibicen can be almost all black, while in other locations their pronotums & mesonotums feature vibrant greens & rusty browns — you can even make out the “M” on the mesonotum.

There may have been cross breeding between the Southern Swamp Cicada (Neotibicen tibicen australis), at some point in time, providing some Neotibicen tibicen tibicen with more colorful appearance. Read Intergrade zones with australis on BudGuide for more information on that possibility.

It is possible to identify Tibicen just after they have molted

Paul Krombholz has come through with an awesome guide to identifying Tibicens just after they have molted. Click the image below for an even larger version. Note that the genus of these cicadas has changed to either Megatibicen or Neotibicen — notes below.

Paul Krombholz's image of recently molted and adult cicadas compared

Notes on the species from Paul:

N. pruinosus [formerly T. pruinosa]—Newly molted adult has darker mesonotum (top of mesothorax) than the very common T. chloromera. Abdomen is a golden orange color. Older adult has dark olive on lateral sides of mesonotum, lighter green below the “arches”.

M. pronotalis (formerly walkeri, marginalis)—Quite large. The reddish brown color can be seen on the mesonotum of newly molted adult. Older adult has solid green pronotum (top of prothorax) and red-brown markings on sides of mesonotum. Below the “arches” the mesonotum color can range from carmel to green. Head is black between the eyes.

N. tibicen [T. chloromerus, T. chloromera]—has large, swollen mesonotum, quite pale in a newly molted adult and almost entirely black in an older adult. Individuals from east coast can have large russet patches on sides of mesonotum. The white, lateral :”hip patches” on the anteriormost abdominal segment are always present, but the midline white area seen in my picture is sometimes absent.

N. davisi—Small. This is a variable species, but all have an oversized head that is strongly curved, giving it a ‘hammerhead’ appearance. Newly molted individuals are usually brown with blueish wing veins that will become brown, but some have more green in wing veins. Some may have pale mesonotums that will become mostly black. Older adults vary from brownish to olive to green markings on pronotum and mesonotum.

M. figuratus [formerly T. figurata]—a largish entirely brown cicada. Newly molted adult has a pink-brown coloration with some blueish hints. Older adult has chestnut-brown markings and no green anywhere. The Head is not very wide in relation to the rest of the body. The small cell at the base of the forewing is black.

M. auletes—a large, wide-bodied cicada. The newly molted adult is very green, but the older adult loses most of the green, usually retaining an olive posterior flange of the pronotum. The dorsal abdomen of the adult has a lot of powdery white on the anterior and posterior segments with a darker band in between.

From my own photos, here’s a sequence of photos of a Neotibicen tibicen tibicen as its colors develop.

Here’s a comparison of two teneral Neotibicen linnei. Note the variation in colors — one green, one pink — from the same grove of trees in New Jersey. Color can vary a lot!

Earlier this week I was lucky enough to find a cicada nymph at a local park in Middletown, New Jersey. I took the cicada home, took some photos and then released it the next day. The cicada turned out to be a female Tibicen tibicen tibicen (formerly T. chloromera) aka a Swamp Cicada.

August is a great time to look for Tibicen cicadas in North America

Filed under: Canada | Tibicen | United States | Video — Tags: — Dan @ 9:33 am

Now is a great time to look and listen for Tibicen cicadas in North America. Tibicen are the medium to large sized annual cicadas. Typically they are well camouflaged – with colors like black, white, green & brown.

During the day you can listen for them, of course, and spot them that way. Try Insect Singers for cicada songs. You can also look for their exuvia (skins), and if you’re lucky you can catch on on a low branch.

Last night I started looking around 10pm and found three Swamp Cicadas (T. tibicen tibicen) shedding their skins on trees around the yard. I also collected about 30 exuvia (skins). All in a quarter acre yard. Take a look at this video:

A Neotibicen tibicen (chloromera) singing

Filed under: Annual | Neotibicen | Tibicen | Video — Tags: — Dan @ 7:41 am

The trees near where I work are chocked full of Tibicen tibicen cicadas (formerly known as T. chloromera, also known as Swamp cicadas).

Here is a short video featuring the call of a Tibicen tibicen that I recorded this morning:

Here’s a sound file of the cicada’s song…

10 new Tibicen photos from Elias Bonaros

Elias was kind enough to send us 10 Tibicen photos he took in 2009. Photos include Tibicen tibicen (chloromera), Tibicen lyricen, Tibicen tibicen & Cicada Killer Wasp on Elias’ fingers, Tibicen canicularis and Tibicen linnei.

Tibicen tibicen

Filed under: Neotibicen | Tibicen — Tags: — Dan @ 9:37 pm

The first time I saw the Genus and species name for this cicada, it was called a Tibicen chloromera:

Tibicen cholormera Cicada

Then its name changed to Tibicen chloromerus, so the gender of the Genus and species name would be in agreement (or so I believe).

Now, this cicada is simply Tibicen tibicen. To read more about why, you’ll need to read Entomological News, Volume 119 Issue 3, “The Identity Of Cicada tibicen Linné [=Tibicen chloromerus (Walker, 1850)] (Hemiptera: Cicadoidea: Cicadidae) no access”.

Here is the abstract:

A lectotype is designated for Cicada tibicen Linné, 1758. The Linnaean specimen located in the Zoological Museum of Uppsala University can be traced to Linné and the original species description. The species is determined to be the same as what is currently recognized as Tibicen chloromerus (Walker, 1850), making T. chloromerus and Cicada sayi Smith and Grossbeck, 1907, junior synonyms of Tibicen tibicen (L.).

Of course you can call it Swamp Cicada, Morning Cicada, or Green Annual Cicada (from Bug Guide). It doesn’t care.

Now do I update all instances of “Tibicen chloromera” on this site, or not. Hmmm….

Time for the yearly Neotibicen post

Filed under: Neotibicen — Tags: , — Dan @ 11:37 am

The Tibicen is the genus of annual cicada most people are familiar with.

Lyric and Swamp Cicada

Here are some general details about Tibicen:

  • They emerge every summer. They do not emerge in broods.
  • They emerge in small numbers (small relative to periodical cicadas).
  • They are timid and elusive compared to periodical cicadas.
  • Most are physically larger than periodical cicadas.
  • They are well camouflaged: their colors and patterns of colors help to hide them in their surroundings. They look like little military vehicles, IMHO.
  • Colloquial names for Tibicens: August Dry Birds, Dog Day cicadas, Harvest Flies, Jar Flies, Bush Cicada (Tibicen dorsatus, formerly T. dorsata)

Swamp cicada

Watch these videos of Tibicen tibicen tibicen cicadas, aka a Swamp Cicada, formerly Tibicen chloromera.

Tibicen tibicen video by Dan.

Note that the music in this 1996 video has nothing to due with cicadas. It’s just crappy science fiction movie music:
