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.

Diceroprocta Paul Krombholz Tacuini (Cryptotympanini) U.S.A.

Diceroprocta vitripennis. out in Mississippi

Here’s a break in the Magicicada mania: a Diceroprocta vitripennis. This photo was taken by Cicada Mania regular Paul Krombholz in Jackson Mississippi just last week. Cicadas like Diceroprocta vitripennis are annual cicadas: they emerge each year in small numbers, and as you can see, they rely on camouflage for survival. Annual cicadas are also quite shy compared to the periodic Magicicadas — they have very different life strategies. American annual cicadas rely on stealth and cunning to survive while searching for a mate. Periodic cicadas rely on the fact that there are so many of them, that some will always survive to carry on the species.

Notes from Paul:

I am continuing this season to try to get pictures of all the cicadas in the
Jackson, Mississippi area. I just got a female specimen of Diceroprocta
vitripennis. I found it in low vegetation on a sand bar next to the Pearl
River. Thanks to John Davis and the collectors at the Mississippi Museum of
Science for the tip on where to look for them! From head to wing tips, it
is 38 mm, but the wings of this species are longer in relation to body
length than those of Tibicens. Body length of this vitripennis was only
22mm.

Kathy Hill Megatibicen Neotibicen Tibicen U.S.A.

Auletes (no Megatibicen grossus) IS the biggest USA cicada!

Cicada researcher Kathy Hill took this unbelievable photo of 18 different USA Neotibicen & Megatibicen specimens, plus a Quesada gigas (upper right) for comparison.

Kathy Hill. Auletes is the biggest Tibicen

Click/tap the image for a much larger version. Contact Insect Singers for more information about the image.

I just took a photo of all the “eastern USA” Tibicens except
latifasciata, which we haven’t got yet (I didn’t include the “little
western” Tibicens like T. texana that are more centrally located
either). But I did also add T. duryi from the west coast and Q.
gigas, just for comparison.

I just wanted to prove that auletes IS the biggest USA cicada 🙂

Note that the these cicadas were reorganized into two new genera: Megatibicen (larger USA Tibicen) and Neotibicen (smaller USA Tibicen) since this original announcement in 2006.

* Note as of 2023 the name of this cicada has changed to Megatibicen grossus. You can also call it a Northern Dusk-Signing Cicada. Cicada names change a lot.

Nine new Neotibicen tibicen photos

These are photos from 2005. Neotibicen tibicen tibicen aka Swamp or Morning Cicada. Back in 2005 we called them Tibicen chloromera.
