Megatibicen grossus odds and ends

Filed under: Exuvia | Megatibicen | Photos & Illustrations — Tags: , — Dan @ 7:44 pm

I had virtually no time in the summer of 2023 to look for cicadas outside my town. Also in 2023, the name of Megatibicen auletes (Germar, 1834) aka Northern Dusk Singing Cicada changed to Megatibicen grossus. While I was not lucky enough to see a Megatibicen grossus, I did find exuvia (molted skins), a headless corpse and some exit holes in late August in the Brendan Byrne park in New Jersey. Something is better than nothing.

Megatibicen auletes is changing to Megatibicen grossus

Filed under: Cryptotympanini | Megatibicen — Dan @ 10:20 am

Update: originally I had Megatibicen grossa, but the name is Megatibicen grossus so the gender of the words align.

Megatibicen auletes (Germar, 1834) aka Northern Dusk Singing Cicada is changing to Megatibicen grossus(Fabricius, 1775). This cicada is the largest cicada in North America and is found in the following states in July-August: AL, AR, CT, DE, DC, FL, GA, IL, IN, IA, KS, KY, LA, MD, MA, MI, MS, MO, NE, NJ, NY, NC, OH, OK, PA, SC, TN, TX, VA, WV, WI.

The change comes from the paper: Sanborn, A.F. (2023) Resolving taxonomic issues of cicadas (Hemiptera: Cicadidae) including new combinations, new synonymies, and revised status, with updates on the diversity of the Brazilian cicada fauna and new records for four South American countries. Zootaxa, VOL. 5318 NO. 3: 20 JUL. 2023, 339-362. DOI: 10.11646/ZOOTAXA.5318.3.2.

Megatibicen grossus (as in BIG FLUTE PLAYER BIG):
Old Ladies

Reading the paper referenced above, it sounds like Johan Christian Fabricius incorrectly identified an specimen as being from Brazil. He named it Tettigonia grossa in 1775. Allen F. Sanborn compared the holotype of Tettigonia grossa with the holotype for Megatibicen auletes (Cicada auletes) and determined it was the same insect. Since old names take precedence over new names, auletes become grossa.

Hieroglyphic cicada locations in New Jersey

Filed under: Megatibicen | Neocicada — Tags: , — Dan @ 6:56 am

Hieroglyphic cicadas (Neocicada hieroglyphica aka Hieroglyphic Cicada) are present in most of southern New Jersey, particularly the Pine Barrens area which has sandy soil (pure sand in a lot of places) and many pine and oak trees. This area is historically prone to fires because of the dry sandy soil and sappy pines. The fact that at least some Hieroglyphic cicadas appear every year and spend many years underground probably helps them circumvent minor fires.

Here’s a photo of a Hieroglyphic and Northern Dusk-Singing Cicada exuvia (shed skin). Quite a difference! Brendan T. Byrne State Forest.
Auletes and Hieroglyphic

Some Locations:

  • Brendan T. Byrne State Forest. Website. This is the best location I’ve found. Pine & oak forests with huckleberry undergrowth. Sandy soil. A good place to record and study their calls, as there is minimal interference from the general public. Exuvia of Hieroglyphic, Northern Dusk-Singing Cicada, and Neotibicen cicadas were easily found. Hieroglyphic Cicada choruses were very loud in the middle of the month (7/10-15), but by 7/31 very few were audible — look for them in late June, or early July.
  • 1900 NJ-70, Manchester Township, NJ. This is a strip mall with a good pizza restaurant (Pop’s), a bar, and a breakfast restaurant. The mall is surrounded by pines and oaks and is a good place for hearing Hieroglyphic and Northern Dusk-Singing Cicadas, as well as some Neotibicen.
  • 1936 Wildland Firefighter Memorial. 151-195 Greenbush Rd. Little Egg Harbor Twp, NJ. An interesting park that features the ruins of some buildings, and the typical combination of sandy soil, pine, oak, and huckleberry. Hieroglyphic cicadas were heard calling on pine trees. I believe this location is within Bass River State Forest.
  • Batso Village. Website. 31 Batsto Rd, Hammonton, NJ 08037. Batso Village is a large recreation of the Batso Village which produced iron and glass in the 18th century. It offers 3 or 4 trails that feature groves of pine trees inhabited by Hieroglyphic cicadas.
  • Franklin Parker Preserve. Website. Chatsworth Lake Entrance, 1450 County Rd 532, Chatsworth, NJ 08019. Some blackjack oak and sassafrass, but the forest is mostly pine. Hieroglphic cicadas are present and audible. The exuvia of small Neotibicen were present, and either N. canicularis or N. davisi are audible (I wouldn’t tell which).

All these areas are heavily infested with ticks, deer flies, and in some cases, mosquitos. Take precaution.

Davis’ Key to Species of the Genus Tibicen found in the Southeastern United States

Davis provided a key of cicadas that belong to the then genus Tibicen in his 1918 article Mississippi Cicadas, with a Key to the Species of the Southeastern United States from volume 26 of the Journal of The New York Entomological Society. Download it from archive.org. This guide works for the Northeast and Midwest as well.

Mississippi Cicadas

Since 1918, genus and some species names have changed, so I’m going to present the key here, with highlighted notes on the updated names + images (when I have them). I’ll try to replicate the formatting of the original document as best I can.

Here goes…

Key to Species of the Genus Tibicen found in the Southeastern United States [works for most states east of the Rocky Mountains].

Note: the cicadas in the key are now organized in three genera: Neotibicen (A B), Megatibicen (A BB), and Diceroprocta (AA).

A. Large, heavy-bodied species; head broad, uncus [male genitals] simple, and first cross vein in the fore wings starting from radius 3 far back or about one-third distant from base of the first marginal cell.

     B. Uncus longer than broad. Black species with green or greenish markings and black area on the central part of the abdomen beneath, except in sayi [sayi = Neotibicen tibicen tibicen], and new variety of davisi [new variety of davisi = Neotibicen davisi harnedi].

Note: this group of cicadas (B) are now organized under the genus Neotibicen, not Tibicen.

         C. Hind margin of pronotum or collar, green or greenish.

             A narrow irregular area of black on the under side of the abdomen; opercula short and broad, and usually in the males an attenuated, pruinose [frosty white] stripe each side on the dorsum of segment three … pruinosa (Say). [pruinosa = Neotibicen pruinosus pruinosus].

N. pruinosus

Neotibicen pruinosus pruinosus

             Dorsum of abdomen with the hind margin of the segments more or less brown and generally but a trace of pruinose stripe each side on segment three … pruinosa var. winnemanna (Davis) [pruinosa var. winnemanna = Neotibicen winnemanna].

[Generally speaking, east of the Appalachian mountains, you’ll find Neotibicen winnemanna, and west, it’s Neotibicen pruinosus.]

Neotibicen winnemanna Garner NC
Photo of a Neotibicen winnemanna.

             Dorsum of abdomen shining black with a broad pruinose mark each side on segment three; blackened area on under side of abdomen more in the nature of an even stripe … pruinosa var latifasciata (Davis) [pruinosa var. latifasciata = Neotibicen latifasciatus].

             A longitudinal band of black on the under side of the abdomen, the opercula more lobate, and the margin of the front wings suddenly bent near the middle … linnei (Smith & Grossbeck) [linnei = Neotibicen linnei].

Neotibicen linnei
Photo of a Neotibicen linnei.

             A definite longitudinal band of black on the under side of the abdomen; head with the front rather prominent. Not a large species … canicularis (Harris) [canicularis = Neotibicen canicularis].

             An irregular band of black on the under side of the abdomen, head rounded in front; a rather small species … davisi (Smith & Grossbeck) [davisi = Neotibicen davisi davisi].

             Abdomen greenish centrally on under side, blackened area wanting, marginal cells of fore wings clouded … davisi var. harnedi new variety [davisi var. harnedi = Neotibicen davisi harnedi].

Krombholz Davisi compared

        CC. Hind margin of pronotum or collar black or nearly so (except in sayi var. australis).

            D. Central area of the abdomen beneath black.

                 Opercula long and with the legs usually somewhat chest- nut colored ; the uncus when seen in profile forked, resembling the open mouth of a snake … similaris (Smith & Grossbeck) [similaris = Neotibicen similaris similaris].

                 Opercula much shorter, more rounded, and the black area on the under side of the abdomen in the nature of an even stripe. Uncus not forked … lyricen (De Geer) [lyricen = Neotibicen lyricen lyricen].

                 Blacker than typical lyricen, lacking the considerable amount of fulvous markings on the pronotum and mesonotum. A fulvous somewhat anchor-shaped mark centrally on the pronotum … lyricen var. engelhardti (Davis) [lyricen var. engelhardti = Neotibicen lyricen engelhardti].

            DD. Central area of the abdomen not black beneath, often pruinose, as well as the long opercula.

                 Collar black, often with a greenish spot each side near the outer angles. … sayi (Smith & Grossbeck) [sayi = Neotibicen tibicen tibicen].

                 Collar all green or nearly so, as well as the pronotum and mesonotum … sayi var. australis (Davis) [sayi = Neotibicen tibicen australis].

    BB. The uncus is broad at the base, triangular in shape, and generally about as broad as long. Opercula broad and rounded at the extremities no definite black area on the central part of the abdomen beneath, usually unicolorus.

Note: this group of cicadas (BB) are now organized under the genus Megatibicen, not Tibicen.

         E. Wings long and narrow, collar 2 mm. or less in breadth at central portions ; dorsum of abdomen black or nearly so.

             Basal cell of fore wings rusty in color, anal cells (membranes) of both pair of wings gray; usually expands 110 mm. or more … resonans (Walker) [resonans = Megatibicen resonans].

         EE. Wings broad, hind margin of the pronotum or collar green or greenish and more than 2 mm. broad.

             F. Anal cells or membranes at base of fore and hind wings gray.

                 Dorsal segments of the abdomen not margined with brown ; in fresh specimens the basal segments pruinose, also the terminal segments, leaving the four middle segments black. A large species expanding over 110 mm. … auletes (Germar) [auletes = Megatibicen auletes].
