“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.
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.
Comments Off on New paper: The periodical cicada four-year acceleration hypothesis revisited and the polyphyletic nature of Brood V
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.

Update! New packaging for the Clustering Cicada fireworks (thx Roy). Find it here.
The Fourth of July should be fun this year at Roy Troutman’s place. Check out the Clustering Cicada fireworks he found.

Is it true that someone has offered a reward for a white or blue-eyed Magicicada cicadas?
This was false and an urban legend until in 2008 when Roy Troutman began to offer rewards for living blue-eyed cicadas for scientific research. All cicadas were released, unharmed.
Important: Roy is no longer offering the reward as he has obtained the cicadas needed for his research. So, don’t bug him, unless you want to tell him that his photos and video are awesome.
White or Blue-eyed Magicicadas cicadas are extremely rare, so finding them can be difficult. I usually find one per emergence, and that is after looking at thousands of cicadas.
Speaking of Roy and White-eyed cicadas, here is a video Roy took of a White-eyed cicada:
And here’s a white and orange-eyed cicada photo taken by Roy:
