Cicada Alphabet: G

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):

Cicada Alphabet: F

F is for flagging. Flagging is the term for when leaves of a tree die as a result of oviposition (when the cicada lays eggs in the branches of trees).

Cicada Alphabet: E

Filed under: Cicada Alphabet — Dan @ 6:38 pm
  • E is for exuvia. People call them shells, skins, cicada ghosts and a dozen other names, but the proper name for what is left behind when a cicada transforms from a nymph to an adult is an exuvia The plural is exuviae. Also known as Integument.
    Cicada skins
  • Egg slits, aka oviposition slits, are the grooves a female cicada makes in a branch in which she will lay her eggs. Here’s a photo of some egg slits and here’s a photo of eggs in a egg slit. Call them oviposition slits if you’re talking to a scientist.
  • Emergence can refer to:
    1. When the adult cicada emerges from its exuvia
    2. When the nymph emerges from the ground
    3. Best answer: When and where a particular group of cicadas will emerge, for example, “There will be an emergence of Periodical cicadas around May 15th in the Nashville Tennessee area in 2011.”
  • Euterpnosia chibensis is a cicada that exists in Japan. Here are some photos of Euterpnosia chibensis. These cicadas are well known in Japan, and there are 3 sub-species: E. chibensis chibensis, E. chibensis okinawana, and E. chibensis daitoensis. These cicadas look a lot like the North American species Neocicada hieroglyphica.

Cicada Alphabet: D

Filed under: Cicada Alphabet — Dan @ 6:39 am

D is for Dog-Day Cicada. The Tibicen canicularis, aka Dog-Day Cicada, is thought to be known as the Dog-Day Cicada because they are most active during the “dog days of summer”, which are the days when the star Sirius is visible in the Northern Hemishphere (July 3-August 11)1. Canicularis is derived from the Latin word canis, which means dog. Tibicen davisi is known as the Southern Dog-Day Cicada. Folks use the term “Dog-Day Cicada” for other species of Tibicen as well, but the T. canicularis the true Dog-Day Cicada.

Diceroprocta is a genus of cicadas that exist in North America.

Diemeniana euronotiana is a pretty black, orange and red cicada that exists in south-eastern coastal area of Australia2. See a photo of a Diemeniana euronotiana.

Cicada Alphabet: C

Filed under: Cicada Alphabet — Dan @ 6:11 am

C is for Cicada Killer Wasp. The Cicada Killer Wasp (in North America, Sphecius speciosus) is a large wasp, which captures adult cicadas, paralyzes them, places them in a burrow, and then lays an egg on them. The cicada dies as it is consumed by the developing wasp larvae. If you want to learn more about these wasps, visit Prof. Chuck Holiday’s Cicada Killer Wasp Website.

As you might guess from Elias Bonaros’ photo, Cicada Killer Wasps are less aggressive towards humans than other wasps, however, we do not recommend approaching them, particularly, if you are a cicada.

A chimney (aka a turret) is a chimney-like structure that a cicada builds above the hole it will emerge from when it’s ready to become an adult. Cicada researchers look for chimneys to get an idea where cicadas will emerge.

Cicadetta calliope (formerly Melampsalta calliope) is a species of cicada found in the South-Eastern United States. It is rust-orange and black, and its eyes are a pretty rose color.

The clypeus is that bulbous structure on the cicada’s head that looks like it could be the cicada’s nose or the grill of a 1950’s automobile. The clypeus holds the muscles the cicada uses to pump plant fluids through its needle-like beak and to its digestive system. Clypeus means shield in Latin.

John Cooley is one of the premier cicada researchers working today. Visit John’s site Cicadas @ UCONN (formerly Magicicada.org), which is dedicated to re-mapping the location of Magicicada broods.

The cruciform elevation is a cross-shaped structure on the dorsal posterior portion of a cicada’s thorax:

Cicada Alphabet: B

Filed under: Cicada Alphabet — Dan @ 10:29 pm

B is for Brood. Here’s the basics:

Marlatt 1907 10 Brood X Magicicada cicadas are American periodical cicadas that have 17 or 13 year life cycles. There are 12 groups of Magicicadas with 17 year life cycles, and 3 groups of Magicicadas with 13 year life cycles. Each of these groups emerge in a specific series of years, rarely overlapping (17 year groups co-emerge every 289 years). Each of these groups emerge in the same geographic area their parents emerged. These groups, each assigned a specific Roman numeral, are called broods.

Two examples:

Brood X (X is the Roman numeral for 10), emerges every 17 years, in DE, GA, IL, IN, KY, MD, MI, NC, NJ, NY, OH, PA, TN, VA, & WV. The last time Brood X emerged was in 2004, and it will emerge again in 2021.

Brood XIX (19) emerges every 13 years, in AL, AR, GA, IN, IL, KY, LA, MO, MS, NC, OK, SC, TN, VA. The last time Brood XIX emerged was 1998, and it will emerge next in 2011 (NEXT YEAR)!

When is the next Brood emerging in your area? Consult the Brood Chart.

I’ve only scraped the surface about the who, why, when, where and how of Broods. If you want to learn more I highly recommend Gene Kritsky’s book Periodical Cicadas: The Plague and the Puzzle. There are also online resources such as Cicadas @ UCONN (formerly Magicicada.org), which has updated brood maps, and Cicada Central.

The interesting thing about Blue Moons is that they’re blue because they lack the yellow pigment necessary to make them green. When they’re green they’re called Green Grocers. Here is a gorgeous photo of a Blue Moon.

A is for antennae. Cicadae antennae are situated between their eyes and their clypeus. Insects use their antennae to smell and sense touch, temperature, and vibration.
