Two new cicada publications worth reading

Two relatively new cicada publications that should be worth reading:

1) Avian Predation Pressure as a Potential Driver of Periodical Cicada Cycle Length by Walter D. Koenig and Andrew M. Liebhold, The American Naturalist. This is a newly electronically published paper about what drives the long, prime-numbered lifecycle of Magicicada periodical cicadas.

Abstract:

The extraordinarily long life cycles, synchronous emergences at 13- or 17-year intervals, and complex geographic distribution of periodical cicadas (Magicicada spp.) in eastern North America are a long-standing evolutionary enigma. Although a variety of factors, including satiation of aboveground predators and avoidance of interbrood hybridization, have been hypothesized to shape the evolution of this system, no empirical support for these mechanisms has previously been reported, beyond the observation that bird predation can extirpate small, experimentally mistimed emergences. Here we show that periodical cicada emergences appear to set populations of potential avian predators on numerical trajectories that result in significantly lower potential predation pressure during the subsequent emergence. This result provides new support for the importance of predators in shaping periodical cicada life history, offers an ecological rationale for why emergences are synchronized at the observed multiyear intervals, and may explain some of the developmental plasticity observed in these unique insects.

Order it from JSTOR.

2) The Cicadas (Hemiptera: Cicadoidea: Cicadidae) of N. America North of Mexico by Allen F. Sanborn and Maxine S. Heath. 227 pages.

A comprehensive review of the North Amerian cicada fauna that provides information on synonymies, type localities, and type material. There are 170 species and 21 subspecies found in continental N. America north of Mexico. The book has 211 figures with each species photographed in color.

Buy it from the Entomological Society of America website. I’ve already ordered mine.

I can’t wait for Sanborn’s book on Central and South America (hopefully, that will arrive within the next few years).

Update:

I’ve received Allen F. Sanborn and Maxine S. Heath’s book. It’s focus is on identifying all species of cicada fauna in North America, north of Mexico, as the title says. It also identifies species that were reported to exist in this location, but do not. The book provides maps and common attributes of each genus of cicada, and then for each species it provides photos of the holotype (and the location of the holotype), as well as a history of its taxonomy.

Blue Cicadas

Blue cicadas. Did you know they exist? They do… at least in Australia.

What’s That Bug recently posted a photo of a blue Bladder Cicada from Australia (Cystosoma saundersii). It’s a great find. Cystosoma saundersii are typically green.

Then there is the Blue Moon blue colored morph of Cyclochila australasiae:

Cyclochila australasiae, Blue Moon, by David Emery
Photo by David Emery

Cyclochila australasiae come in many colors, but the most common color is green. “Blue Moon” is a good nickname for these cicadas because they are rare and only found, idiomatically speaking, “once in a Blue Moon”.

So, why are some cicadas blue, when their species is typically green? Here is a quote from the paper Blue, red, and yellow insects by B. G. BENNETT, Entomology Division, DSIR, Private Bag, Auckland, New Zealand:

The colours of insects are often due to a complex mixture of pigments, some of which
are concentrated from their diet. These are carotenoids, flavonoids, and anthraquinones, and some are porphyrins made from the breakdown of plant chlorophyll. Insectoverdin is a common green pigment produced by a mixture of blue and yellow compounds. The blue is tetrapyrrole, but sometimes an anthocyanin, and the yellow is a carotenoid.

Blue + yellow = green. If the yellow is missing, you get a blue cicada. I heard that, at least in the case of the Cyclochila australasiae, the blue cicadas are typically females. Perhaps something related to genetics or behavior of the females leads to an inability to process the caroteniods ingested along with their diet (tree fluids). I’m not sure, but it’s a topic that fascinates me, so I’ll continue to look into it.

Great website: The cicadas of central eastern Australia

If you are located in Australia and like cicadas, you should visit The cicadas of central eastern Australia, a website created by Lindsay Popple.

Popple’s website includes: photos, maps, range & season, habits, and recordings of the song of dozens of Australian cicadas. Very complete and well done.

The site was recommended to me by David Emery.

Brazil Cicada Identification Challenge, Part 2

Here is part 2. Jairo of Cigarras do Brasil — Brazilian Cicadas asked for our help to identify some unknown cicada species from Brazil. The following photographs feature cicadas from Brazil we want to identify. We are hoping folks in the cicada research community can help.

Note: All of these cicadas were photographed at Paraibuna, São Paulo. This town is close to the Paraíba Valley (Vale do Paraíba), and to São José dos Campos and Caçapava.

1) Possibly an Ariasa sp. (about 1/2 inch (1,3cm))

The New Forest Cicada Project

I mentioned the New Forest Cicada a few weeks ago. It is the only cicada native to the United Kingdom, but no one has observed it since 2000, so it might be extinct. I hope it is not extinct.

Now there is a team of researchers called The New Forest Cicada Project who plan to use a smartphone app, for your Android or iOS device, to listen for and identify the cicada.

Do you live in England? Are you in the area of the New Forest National Park? If so, make sure you download the app when it’s ready and then next May-July, go listening for the New Forest cicada.

This story was also mentioned in a Guardian UK article.

New Forest cicada (Cicadetta montana)

There is only one type of cicada in the United Kingdom, and it is called the New Forest cicada (Cicadetta montana). It is named for the New Forest National Park, where these cicadas can be found in the pasture woodlands. It is both rare and endangered, according to this FAQ, however, according to another website, it might be extinct. It sounds like a small gas motor (in my opinion).

The website ARKive has Five videos of the New Forest cicada, including one featuring cicada larvae still in a tree branch.

Cicadas belonging to the Genus Cicadetta are known as “small grass cicadas”. The New Forest cicada belongs to the same subfamily (Subfamily Cicadettinae) as the Magicicada periodical cicadas that live in the U.S.A.

Fukushima radiation possibly impacting cicadas in Japan

Update: @Zi_kade on twitter (he’s a cicada expert in Japan) said that these deformities were caused by wind. Good news.

Radiation from the Fukushima reactor is possibly impacting cicadas in Japan. I say possibly, because I don’t know for sure, but the following articles infer that radiation is playing a part in cicada deformities and complications during molting (when they shed their nymph skins and become adults). Looks like about 20% of cicadas are affected in the study mentioned in the articles. It will be interesting to see how this story plays out. If the affected cicadas were in areas that flooded during the tsunami, it could be their bodies were damaged by water soaking the ground or flooding their tunnels.

Breaking News: Radiation has started attacking DNA.
