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…

Tibicen auletes from North Carolina

Filed under: Annual | Megatibicen | Tibicen — Tags: — Dan @ 8:00 am

Here’s a Tibicen auletes found in Winston-Salem, North Carolina by my friend Erin Dickinson. The T. auletes is also known as Northern Dusk Singing cicada. It can be found in most Southern states, IL, IN, MI, OH, MD, DE, NJ and CT.

The Tibicen auletes is the largest species of the Tibicen cicadas (largest in terms of physical size). Visit Insect Singers to hear its song.

Walker’s Cicada aka Megatibicen pronotalis (aka T. walkeri, T. marginalis)

Filed under: Annual | Roy Troutman | Tibicen — Tags: — Dan @ 7:24 pm

Roy Troutman sent us these amazing photos of a female Walker’s Cicada aka Megatibicen pronotalis (aka T. walkeri, T. marginalis) taken in Batavia, Ohio. As you can guess by the various akas (also known as), the Megatibicen pronotalis has been known by several species names in the past. Sometimes it takes cicada researchers a while to figure out that two different species are the same species (which is probably the case here). Tibicen pronotalis also sounds exactly like another species of Tibicen: Megatibicen dealbatus. The major difference between the M. pronotalis and the M. dealbatus is the M. dealbatus has more pruinose than the M. pronotalis. Pruinose is the white, chalky substance that appears on the bodies of cicadas.

It’s the season for annual cicadas

Filed under: Annual | Tibicen | Video — Dan @ 8:48 pm

The Brood XIX (and Brood IV stragglers) are all but gone, but annual species of cicadas are emerging around the United States right now. The various annual species of cicadas differ from periodical cicadas in many ways. Annual cicadas emerge in limited numbers every year, they are not organized into broods, they tend to be timid and camouflaged to match their environment, and while their life cycles are longer than a year, they are not as long as 13 or 17 years.

The most common annual cicada east of the Rockies is probably the various species of the Tibicen genus. There are also cicadas belonging to the Diceroprocta, Neocicada, and Okanagana genera out and about now.

Use the Insect Singers website to help match the species to their song.

What’s in a name?

Filed under: Tibicen — Dan @ 5:57 pm

We’ve discussed, in previous posts, issues with the naming of Tibicen cicadas; first there were gender agreement issues and then the naming of Tibicen tibicen cicadas (which most people still refer to as Tibicen chloromera).

The gender issue deals with agreement of the Genus and species name. Tibicen superba, for instance, should be called Tibicen superbus since the “en” in Tibicen is male, and the ending of suberbus needs to match that with “us”.

Quoting from Bug Guide1:

“All the —a endings in the species of Tibicen need to be —us, e.g. bifida should be bifidus”, per Allen Sanborn (Barry University, Florida), pers. comm., 2008. (Note, many taxonomists working on larger groups, e.g. leps, have abandoned gender agreement, but apparently this isn’t the case with Cicadas. MQ)

The story for Tibicen chloromera is a bit different. First, chloromera needed to be changed to chloromerus because of the gender agreement issue. Then that had to be changed to Tibicen tibicen because historically this particular cicada was referred to as Tibicen tibicen before Tibicen chloromera. This could be changed, if someone found a precedent of the insect being called a Tibicen chloromera, but then still we’d have to call it a Tibicen chloromerus because of the gender agreement issue.

Quoting from Bug Guide again2:

The long-standing name for this common species, Tibicen chlormera, has apparently been changed to Tibicen tibicen based on priority. See Synonyms and references. –Cotinis 17 October 2008.

That being said, most folks on the web call the Tibicen tibicen “Tibicen chloromera” to this day. Whether this is an act of rebellion, force of habit, loyalty to other researchers who don’t agree with the name change, I’m not sure.

Taxonomic name changes discussed, lets move to common Tibicen names.

Our last post featured Elias Bonaros photo of a Tibicen auletes, which I labeled a Scissor-grinder, a common name for the insect — or so I thought. Elias was quick to point out that other resources call another cicada, the Tibicen pruinosus, a Scissor-grinder. Elias is no slouch when it comes to cicada information, and he has correctly corrected me in the past in mistakes I’ve made, but I needed to figure out where i got my possibly erroneous information from.

Bug Guide calles the T. auletes a Scissor-grinder3 as well as Northern Dusk-singing cicada, as does another IOWA State website4.

University of Florida scientists/researchers, on the other hand, call the Tibicen pruinosus5 a Scissor-grinder as does the Song of Insects6 website. The University of Florida document doesn’t provide a common name for T. auletes, but the Song of Insects site refers to them as Northern Dusk-singing Cicadas.

So… any tie breakers out there? It could be that in the South the T. pruinosus is the Scissor-grinder and in the Mid-west it’s the T. auletes.

Hot weather means cicadas emerge sooner? Most likely.

Filed under: Neocicada | Tibicen — Dan @ 7:56 am

Temperature is a factor influencing when cicadas will emerge from the earth and enter the adult phase of their lives. Cicadas like warm weather (as do most insects) and so once the soil & air reaches a temperature that pleases the cicadas, they will likely emerge. There are other factors of course, but hotter weather usually means cicadas will emerge sooner than later.

The spring and summer of 2010 have been HOTTER than usual in the mid-Atlantic area of the United States, and so species of cicadas are emerging earlier than expected. Since June first, I’ve witnessed, 32 days above 80F(27C), and 11 days above 90F(32C), in New Jersey, which is warmer than usual.

Annual cicada species like the Tibicen species and Neocicada hieroglyphica have been emerging sooner than expected. Cicadas.info has reports of Neocicada hieroglyphica, Tibicen lyricen and T. tibicen (T. chloromera) emerging sooner than expected. I’ve been hearing T. linnei in New Jersey since June.


Massachusetts Cicadas
is reporting a slow start for Tibicen. Massachusetts is a New England state and is typically cooler than Mid-Atlantic states like New Jersey, but that might not be the only factor at work here. It will be interesting to see how this plays out.

What else…

The temperature will also affect when a cicada will sing: if it’s too cold cicadas won’t sing, and if it’s too hot the poor over-heated cicadas won’t sing. This is why you won’t hear some annual cicadas singing on a cool day, or when it’s near 100F(38C). This depends on the species too; some species like it HOT, and some like it cool.

I’ve also heard that temperature can affect the frequency of a cicada’s song, however, there is not a formula that allows to you determine the temperature based on the pauses in a cicada’s call like there is for crickets.

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 by CicadaMania.com

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….

Megatibicen auletes found by Elias Bonaros in New Jersey

Filed under: Elias Bonaros | Megatibicen | Tibicen — Tags: — Dan @ 9:02 pm

You might know Elias from his posts on the Message Board. Monday, after a lot of searching, he found a female Tibicen auletes in Lakewood New Jersey.

I was down in Lakewood NJ yesterday and after finding 5 more additional huge exuvia, the unthinkable happened. a female T. auletes flew to a light, hit the pole after circling many times and slid down to the ground. I easily captured her on the ground. Wanted to share this picture. look how beautiful she is with all that pruinosity!

Tibicen auletes are the largest of the North American Tibicen species. Their bodies a a little under 2″ long. Auletes are also know as the Sissor-Grinder, Northern Dusk-singing Cicada, or Great Dusk-calling Cicada. Read more at Bug Guide. The Songs of Insects site has sound files so you can listen and hear if you have auletes in your yard too.

Here’s Elias’ photos:
