A Green Grocer:
C. australasiae (Donovan, 1805)

Cyclochila genus description by W. L. Distant:

Characters. — Head about long as breadth between eyes, including eyes distinctly narrower than pronotum but almost as wide as its anterior margin, ocelli close together near middle of vertex, very much more remote from eyes than from each other; face longer than broad, moderately globose; pronotum about as long as mesonotum including the cruciform elevation, its lateral. margins moderately convexly ampliated ; abdomen about as long as space between apex of head and base of cruciform elevation, beneath moderately convex ; opercula short, not passing base of abdomen ; tegmina about or nearly three times longer than broad, basal cell scarcely longer than broad, apical areas eight; wings more than half the length of tegmina, apical areas six.

Green Grocer

I felt bad about always using an illustration of North American cicadas, so I made a Green Grocer cicada for Australian fans.

Get this image on a shirt, mug or even a pillow case via CafePress (the mugs are the most affordable).

A third way cicadas make sounds

Filed under: Australia,Cicada Anatomy,Cyclochila,Sounds,Video — Dan @ 8:06 am

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:
Collar

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.

Masked Devil aka Cyclochila australasiae

Filed under: Australia,Cyclochila — Dan @ 4:37 am

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.

Masked Devil

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.

More info about Cyclochila australasiae from L.W. Popple’s website.

Cicada Season has begun in Australia

Filed under: Australia,Cyclochila,Cystosoma,David Emery,Pauropsalta — Dan @ 8:40 pm

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!

Cheers, David.

Cicada Mania: Y

Filed under: Australia,Cicada Alphabet,Cyclochila — Tags: , — Dan @ 6:46 pm

Y is for Yellow Monday Cicada. The Yellow Monday cicada is the yellow form of the Cyclochila australasiae (the green form is the Green Grocer). Yellow Monday Cicadas lack a turquoise pigment that normally combines with the yellow pigment to form a green color. Visit the Scribbly Gum website for a photo and more information about Yellow Mondays.

Almost a Yellow Monday, this C. australasiae is mostly yellow and a little green:

G is for Greengrocer. The Greengrocer is the green morph of the Australian cicada Cyclochila australasiae. These cicadas can be found in south-eastern Australia. They have a large pronotal collar, and if you use your imagination, it looks like they’re wearing a tiny Pith helmet above their eyes.

Here’s a close of up of a Greengrocer (from Bron):

Green Grocer

Filed under: Australia,Cyclochila — Tags: — Dan @ 12:14 pm

Bron sent us this Green Grocer photo taken in Orange NSW Australia.

Green Grocer Cicada

The scientific term for Green Grocers is Cyclochila australasiae. The come in other varieties such as the yellow colored Yellow Mondays and blue Blue Moons.

Cyclochila australasiae can be found in eastern Queensland, NSW and Victoria, and most emerge in October and November (Moulds, M.S.. Australian Cicadas Kennsignton: New South Wales Press, 1990, p. 61.).
