This photo points out the Tymbal (the organ that makes the cicada’s signature sound), the Tympanum (their hearing organ), the Operculum (which covers the Tympanum), and its wings.

Genera of cicadas.
It looks like a new sub-tribe, genus and species of cicada has been identified by Michel Boulard and Stéphane Puissant. Cicadmalleus micheli. The cicada has a head that looks like the head of a hammerhead shark! Cicadmalleus means “cicada hammer”, and micheli refers to Bruno Michel who found the cicada (thanks David Emery).
I heard the cicada was discovered in Thailand, which makes sense because that is where Michael Boulard does most of his research.

This is a photo of one of my displays at home. Some of the specimens aren’t in the best shape, but it is good enough to distinguish the species.
Angamiana floridula, Becquartina electa, Gaeana cheni, Gaeana festiva, Platypleura mira, Tacua speciosa, Tosena albata, Tosena melanoptera, Tosena paviei, and Trengganua sibylla are featured in the image.
Kees Green sent us many photos of cicadas taken in Australia.
Here is a sample:
A Green Grocer (Cyclochila australasiae) nymph:
An unidentified Pauropsalta sp.:
A Thopha sessilibia:

M. cassini in Connecticut
A news story came out in November reporting that M. cassini appeared in areas of Connecticut where they were not expected during the Brood II emergence this year. This must have been a 2013 highlight for cicada researchers in the Connecticut area.

Macro photo of a Floury Baker
This is a wonderful macro photo of a Floury Baker (Aleeta curvicosta) from Australia. Thanks to Cameron for posting this photo on our Facebook page.
This video taken by Samantha Madell in NSW Australia is a time lapse video of of a Redeye Cicada (Psaltoda moerens) molting.
A new species of Tibicen cicada, Tibicen neomexicensis, has been described by Brian J. Stucky.
Thanks to David Marshall for the tip.
Just in time for Halloween… the Zammara a genus of cicadas with a collar like Dracula!
Andreas Kay has been posting photos of the insects of Ecuador on Flickr for around a year now. He’s posted many excellent cicada photos, particularly, photos of Zammara. They are among the most visually interesting cicadas.
Emerald Cicada, Zammara smaragdina:
Here’s an illustration from Insecta. Rhynchota. Hemiptera-Homoptera. Vol. I by W. L. Distant and The Rev Canon W. W. Fowler, F.L.S:
Here the Scientific classification:
Family: Cicadidae
Subfamily: Cicadinae
Tribe: Zammarini
Genus: Zammara
Species: Zammara smaragdina Walker, 1850
Here’s an article about Collared cicadas of Mexico, Central & South America.
Cicadas are well known for the songs male cicadas make with their their tymbals, which are drum-like organs found in their abdomens.
Some female cicadas will also flick their wings to get the males attention. Watch this video where a male Magicicada is convinced that the snapping of fingers is a wing flick. Note: Magicicada males will also flick their wings once they become infected with the Massospora cicadina fungus (which removes their sex organs).
There is a third way some cicadas can make sounds. This method of creating a sound is unique to the Australian species Cyclochila australasiae (aka the Green Grocer and Masked Devil). These cicadas have stridulatory ridges on their pronotal collars (the collar shaped structure at the back of their head), and a stridulatory scraper on their fore wing.
From M. S. MOULDS, 2012, A review of the genera of Australian cicadas (Hemiptera: Cicadoidea). Magnolia Press Auckland, New Zealand. p84:
Cyclochila is unique among the Cicadoidea in possessing a stridulatory file on the underside of the lateral angles of the pronotal collar that interacts with a scraper on the fore wing base (Fig. 132). Rubbed together these produce low audible sound in hand-held specimens (K. Hill, pers. comm.), the purpose of which is for sexual com- munication at close quarters (J. Kentwell and B. Fryz, pers. comm.)
Here is a photo of these structures:
The location of these structures is right about where the blue pin is in this photo:
Update:
Tim McNary of the Bibliography of the Cicadoidea website, let us know that Clidophleps cicadas are also able to create should using a stridulatory structure. Clidophleps is a genus of cicada that can be found in California, Nevada, Arizona, and I assume adjacent parts of Mexico. Clidophleps differs from Cyclochila in that the stridulatory structure is on its mesonotum, and not its pronotal collar.
