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.

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:
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.

Lozang Yönten posted this image of a Masked Devil aka Cyclochila australasiae on our Facebook page. The photo was taken in the Blue Mountains, NSW, Australia.
These cicadas are currently out and singing in the New South Wales area.
The green form of this cicada is called a Green Grocer, the yellow form is called a Yellow Monday, and the Blue Form is called the Blue Moon. The Cyclochila australasiae might have more color variations than even the Gaeana festiva of Southeast Asia.

We expect Magicicadas with a 13-Year life-cycle to emerge in Ohio & Kentucky, along the Ohio river, in 2014. This particular group of periodical cicadas last emerged in 2001 and 1988.
I know what you’re thinking: are these cicadas part of Brood XXII? Time and research will tell. Brood XXII emerges in Louisiana and Mississippi, which are geographically isolated from Ohio & Kentucky, so the two groups of cicadas are likely to be genetically distinct (belonging to different mitochondrial haplotype groups at least). That said, Brood II, which emerges mostly along the east coast of the U.S., also emerges in Oklahoma, which is geographically isolated from the rest of that brood. So, the Ohio/Kentucky cicadas could logically be part of brood XXII.
My guess is these cicadas are somehow descended from Brood X or Brood XIV 17-year cicadas, and that if they are 13-year cicadas, there would be no M. neotredecim present in this brood.
I wrote Roy for a list of towns where these cicadas emerged in 2001, and he said:
Cold Springs, KY
New Richmond, OH
Point Pleasant, OH
Woodland Mound Park, Cinncinati, OH

Magicicada Brood XXII, the Baton Rouge Brood, will emerge in 2014 in Louisiana and Mississippi.
Some Brood XXII facts:
- Brood XXII Magicicadas have a 13-year life cycle.
- Three of the four 13-year Magicicada species, M. tredecim, M. tredecassini, and M. tredecula, belong to Brood XXII.
- The last time Brood XXII emerged was 2001.
- We received reports from Baton Rouge, LA, Houma, LA, Pride, LA, Weyanoke, LA, Vicksburg, MS and Natchez, MS in 2001

David Emery wrote to let us know that cicada season has begun in parts of Australia:
After some 50mm of rain on 16-17 Sept and the warmest winter on record on the east coast, the “masked devil” morphs of Cyclochila australasiae were in good voice in the mountains west and south of Sydney, Australia on 22nd Sept. The bladder cicadas (Cystosoma saundersii) are also rattling in Metro Sydney. These are about 2 weeks early this year as are several of the smaller grass cicadas and Pauropsalta species. Roll on summer!

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:

Last night I went on an exploration of Manchester, NJ looking for Tibicen auletes (Germar, 1834) with Elias Bonaros and his friend Annette.
T. auletes, are known as the Northern Dusk Singing Cicada. As their name suggests, T. auletes calls at dusk, around sunset. Their call is amazing – visit Insect Singers to hear their call.
Luckily I found a (deceased) female and an exuvia (nymph skin). Elias and Annette found many exuvia and a live nymph. We were able to watch the nymph undergo ecdysis (leave its exuvia, and expand its adult body).
Here are some images of the cicadas we found last night (click the first two images to get to larger versions):
