Cicadas @ UCONN, a new Cicada website

Filed under: John Cooley | Magicicada | Periodical | United States — Dan @ 9:12 pm

Magicicada.org was an amazing website filled with information about Magicicada periodical cicadas and backed by cicada expert, John Cooley.

The site now has a new address and look: Cicadas @ UCONN (https://cicadas.uconn.edu/). Bookmark it in preparation for the 2021 Brood X emergence.

Cicadas @ UCONN

UCONN (University of Connecticut) has other cicada websites such as The Simon Lab and Cicada Central.

New paper: The periodical cicada four-year acceleration hypothesis revisited and the polyphyletic nature of Brood V

A new paper about periodical cicadas! View it: https://peerj.com/articles/5282/

“The periodical cicada four-year acceleration hypothesis revisited and the polyphyletic nature of Brood V, including an updated crowd-source enhanced map (Hemiptera: Cicadidae: Magicicada)”

Authors: John R. Cooley​, Nidia Arguedas, Elias Bonaros, Gerry Bunker, Stephen M. Chiswell, Annette DeGiovine, Marten Edwards, Diane Hassanieh, Diler Haji, John Knox, Gene Kritsky, Carolyn Mills, Dan Mozgai, Roy Troutman, John Zyla, Hiroki Hasegawa, Teiji Sota, Jin Yoshimura, and Chris Simon.

Abstract:

The periodical cicadas of North America (Magicicada spp.) are well-known for their long life cycles of 13 and 17 years and their mass synchronized emergences. Although periodical cicada life cycles are relatively strict, the biogeographic patterns of periodical cicada broods, or year-classes, indicate that they must undergo some degree of life cycle switching. We present a new map of periodical cicada Brood V, which emerged in 2016, and demonstrate that it consists of at least four distinct parts that span an area in the United States stretching from Ohio to Long Island. We discuss mtDNA haplotype variation in this brood in relation to other periodical cicada broods, noting that different parts of this brood appear to have different origins. We use this information to refine a hypothesis for the formation of periodical cicada broods by 1- and 4-year life cycle jumps.

New paper on the molecular phylogeny of the cicadas and tribe and subfamily classification

A new paper has been published titled A molecular phylogeny of the cicadas (Hemiptera: Cicadidae) with a review of tribe and subfamily classification by David C. Marshall, Max Moulds, Kathy B. R. Hill, Benjamin W. Price, Elizabeth J. Wade, Christopher L. Owen, Geert Goemans, Kiran Marathe, Vivek Sarkar, John R. Cooley, Allen F. Sanborn, Krushnamegh Kunte, Martin H. Villet, Chris Simon.

The paper was published in Vol 4424, No 1 of Zootaxa. Link to paper.

In a nutshell: These researchers compared the DNA of a variety of cicadas to determine how they are related evolutionarily and how they should be organized in terms of tribes and sub-families.

Abstract:

A molecular phylogeny and a review of family-group classification are presented for 137 species (ca. 125 genera) of the insect family Cicadidae, the true cicadas, plus two species of hairy cicadas (Tettigarctidae) and two outgroup species from Cercopidae. Five genes, two of them mitochondrial, comprise the 4992 base-pair molecular dataset. Maximum-likelihood and Bayesian phylogenetic results are shown, including analyses to address potential base composition bias. Tettigarcta is confirmed as the sister-clade of the Cicadidae and support is found for three subfamilies identified in an earlier morpho- logical cladistic analysis. A set of paraphyletic deep-level clades formed by African genera are together named as Tettigo- myiinae n. stat. Taxonomic reassignments of genera and tribes are made where morphological examination confirms incorrect placements suggested by the molecular tree, and 11 new tribes are defined (Arenopsaltriini n. tribe, Durangonini n. tribe, Katoini n. tribe, Lacetasini n. tribe, Macrotristriini n. tribe, Malagasiini n. tribe, Nelcyndanini n. tribe, Pagi- phorini n. tribe, Pictilini n. tribe, Psaltodini n. tribe, and Selymbriini n. tribe). Tribe Tacuini n. syn. is synonymized with Cryptotympanini, and Tryellina n. syn. is synonymized with an expanded Tribe Lamotialnini. Tribe Hyantiini n. syn. is synonymized with Fidicinini. Tribe Sinosenini is transferred to Cicadinae from Cicadettinae, Cicadatrini is moved to Ci- cadettinae from Cicadinae, and Ydiellini and Tettigomyiini are transferred to Tettigomyiinae n. stat from Cicadettinae. While the subfamily Cicadinae, historically defined by the presence of timbal covers, is weakly supported in the molecular tree, high taxonomic rank is not supported for several earlier clades based on unique morphology associated with sound production.

New paper: Massospora cicadina hijacks the sexual signals of periodical cicadas

A new paper, A specialized fungal parasite (Massospora cicadina) hijacks the sexual signals of periodical cicadas (Hemiptera: Cicadidae: Magicicada), has been published by John R. Cooley, David C. Marshall & Kathy B. R. Hill, in Scientific Reports 8, Article number: 1432 (2018).

Read the paper online.

In a nutshell: the fungus infects males and causes them to exactly mimic the mating behavior of female cicadas, thus infected males end up spreading the fungus to uninfected males.

Abstract:

Male periodical cicadas (Magicicada spp.) infected with conidiospore-producing (“Stage I”) infections of the entomopathogenic fungus Massospora cicadina exhibit precisely timed wing-flick signaling behavior normally seen only in sexually receptive female cicadas. Male wing-flicks attract copulation attempts from conspecific males in the chorus; close contact apparently spreads the infective conidiospores. In contrast, males with “Stage II” infections that produce resting spores that wait for the next cicada generation do not produce female-specific signals. We propose that these complex fungus-induced behavioral changes, which resemble apparently independently derived changes in other cicada-Massospora systems, represent a fungus “extended phenotype” that hijacks cicadas, turning them into vehicles for fungus transmission at the expense of the cicadas’ own interests.

And now, because I need an image for the post: a meme:

Fungus Bae

Cicadas, when infected, are called “salt shakers of doom”. Add that to the meme “Salt Bae”, and the image makes sense.

New paper about Brood XXII Magicicadas

There is a new paper out about Brood XXII, titled Evolution and Geographic Extent of a Surprising Northern Disjunct Population of 13-Year Cicada Brood XXII (Hemiptera: Cicadidae, Magicicada). I helped with the field work for this paper, traveling through Ohio and Kentucky with Roy Troutman, recording the locations of periodical cicadas.

Brood XXII, a brood of Magicicada periodical cicadas with a 13-year lifecycle, exists in Louisiana & Mississippi, and Ohio & Kentucky with no geographic connection between them (the two groups are geographically isolated). The paper discusses the similarities and differences between the two groups.

You can read and download the paper for free.
