Magicicada nymphs found by Elias, part 2

Filed under: Elias Bonaros,Magicicada,Nymphs,Periodical — Dan @ 6:02 am

Continuing from part 1, Elias Bonaros did some digging and took these photos of first and second instar Magicicada periodical cicadas on a warm winter day (March 21, 2010).

Now you know what cicadas look like when they’re underground!

Generally speaking the ones with the bulbous abdomens are second instar, and the smaller ones with the less bulbous or not bulbous abdomens are first instar.

Have you every wondered what cicadas look like when they’re underground? Elias Bonaros did some digging and took these photos of first and second instar Magicicada periodical cicadas on a warm winter day (March 21, 2010). Magicicadas have 5 instars, or phases of development. Each phase has a slightly different appearance.

This is a probable second instar nymph of Magicicada septendecim (Periodical cicada) from the 2008 Brood XIV emergence. Dug up from beneath an oak tree. It was living approximately 4-6 inches from the ground surface. Temperature 70 degrees.

Okanagana rimosa exuvia (skins, shells) photos by Elias Bonaros. From 2010, I believe.

Note the dark lines on the abdomen — that’s an easy way to distinguish Okanagana exuvia from other types of cicadas.

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.

Linne’s Cicada in Cape May County, NJ

Filed under: Elias Bonaros,Neotibicen — Tags: — Dan @ 8:15 pm

Here’s some footage of a Neotibicen linnei in Woodbine, Cape May County, NJ.

Elias almost caught it.

This footage was a byproduct of our cicada hunt for a different cicada, Neotibicen latifasciatus.
