For Immediate Release

Jennifer Angus: Magicicada
New exhibition of insect-based art opens July 16 at the Staten Island Museum

(Staten Island, NY – June 29, 2021) As Brood X wanes, cicadas emerge anew at the Staten Island Museum with Jennifer Angus: Magicicada, a new exhibition opening Friday, July 16 2021 and running through May 22, 2022.

Magicicada is an immersive exhibit featuring exquisite ornamental patterns and imaginative vignettes created by artist Jennifer Angus using hundreds of preserved insects. Taking inspiration from the Museum’s collection of cicadas- one of the world’s largest- the installation will feature over two dozen species of cicada, including Brood X periodical cicadas, or Magicicadas, collected during the 2021 emergence.

“Cicadas, and Magicicada in particular, have a deep connection and meaning to the Staten Island Museum. Founder William T. Davis was the cicada expert during his lifetime and was even the one who coined the name Magicicada, capturing the wonder of the periodical cicadas’ mass emergences and long disappearances. It is especially poignant that this exhibit is opening as we are also remerging into the world after a time of darkness. I am hopeful that it can bring people a sense of joy and wonder after a time of profound loss.” Colleen Evans, Staten Island Museum Director of Natural Science.

Using responsibly collected and preserved specimens, Angus creates site-specific installations with hundreds of insects pinned directly to walls, creating patterns reminiscent of textiles or wallpaper. Up close, the installations reveal themselves to be comprised of actual insects, often species that are not traditionally considered beautiful. Angus’s installations also include Victorian-style insect dioramas in antique furniture and bell jars. Her work motivates viewers to find beauty in unexpected places and to understand the importance of insects and other creatures to our world.

In preparation for this exhibit, Angus spent time in the Museum’s extensive natural history collections to help shape the finished show. Select objects and specimens from the natural science collection, including retired collection storage and historic taxidermy, will be featured throughout the gallery amidst Angus’s fanciful arthropod arrangements. During the spring Brood X emergence, she traveled to Princeton, NJ along with the Museum’s Director of Natural Science, Colleen Evans, and Joseph Yoon from Brooklyn Bugs to observe and collect cicadas for the show.

Artist Jennifer Angus states: “I often say that the meat and potatoes of my installations are cicadas. They come big and small. Tropical species often can have colourful wings causing many people to assume they are moths, but unlike those insects, cicadas are tough, hardy creatures standing up to repeated use in my art installations. I could not have been more delighted when the SIM contacted me, and I learned of founder William T. Davis’ passion for cicadas which were an under documented species in his day. I have had the privilege of exploring the SIM’s collection, the one of the largest of cicadas in the world, and have been inspired by these mysterious creatures who spend most of their lives underground but upon emerging let us all know of their presence with loud calls. That Brood X periodical cicadas have emerged this year as well is a joyous event and has brought considerable notice to cicadas. I deeply appreciate the assistance provided by the SIM’s staff in working with me to celebrate the cicada.”

Magicicada is supported in part by an award from the National Endowment for the Arts.

Staten Island Museum is supported in part by public funds provided through the NYC Department of Cultural Affairs and by the New York State Council on the Arts.

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

Filed under: Cryptotympanini | Diceroprocta | Megatibicen | Neotibicen | William T. Davis — Dan @ 10:00 pm

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

             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

        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].

Wm T Davis’ 1910 description of Neotibicen lyricen engelhardti1

Cicada engelhardti n. sp.

Length: [male] 32 mm., to tip of wings, 50 mm.; [female] 30 mm., to tip of wings 50 mm.

Head black, sometimes with narrow, tawny stripe on front. Pro-thorax black, with small, greenish fulvous central arrow-shaped spot, broadest behind. In lyricen this spot is broadest in front. Posterior and lateral borders of the pronotum black. Mesothorax nearly all black, with two faint parenthesis-like lines of fulvous partly enclos- ing the central portion. Sometimes these lines are heavier and there is a shade of fulvous on the posterior portion of the mesothorax. The inner surface of the front marginal vein is usually back and darker than the same parts in lyricen. Abdomen black above, with two nar- row pruinose lines or spots at base. Beneath, with broad central black stripe and at each side is a broad lateral pruinose border.

This insect is blacker than Cicada lyricen, lacking the considerable amount of fulvous markings of that species, particularly on the pro- thorax.

Name, Location and Description

Wm. T. Davis description

Neotibicen latifasciatus was described in 1915 by Davis in the article Notes on Some Cicadas from the Eastern and Central United States with a Description of a New Variety of Cicada Pruinosa in the Journal of The New York Entomological Society. 1

Smith and Grossbeck say of the specimens they had from the coast of New Jersey and which we now know to be a variety: “Abdomen above black, base of first segment with a white, heavily pruinose lateral dash, which encroaches to some extent upon the second segment; a similar but longer and broader lateral dash extends along the base of the third segment and a spot of the same color is on each side of the eighth segment. In the female the dash of the second segment differs from that of the male in not becoming attenuated dorsally, but in being squarely truncated.”

For the variety thus described with the broad white lateral dashes on segment three, we propose the name of latifasciafa. We then have Cicada pruninosa [now Neotibicen pruinosus] as described by Say, with the tergum entirely black or nearly so, with the attenuated white stripe at the lateral base of the third abdominal segment, being the form common from Indiana, Missouri, Nebraska, Kansas, etc., of which we figure a male from Chetopa, Kansas ; Cicada pruinosa var. latifasciata so far known only from the coastal region of the eastern and southern United States, with the broad stripe on segment three and abdomen beneath more shining black, of which we figure a male from Cape May Co., New Jersey, and Cicada pruninosa var. winnemanna [now Neotibicen winnemanna] with the hind margins of the abdominal segments more or less fulvous, the second segment having the band broader than the others and a white streak generally hardly discernible each side at the base of the third segment, of which we figure a male from Plummer’s Island, Maryland. The females of these cicadas have the charactertistic markings far less distinct than in the males and occasionally some are entirely absent.

Identification key by Wm T Davis2

A. Large, heavy bodied species ; head broad, uncus simple, and first cross vein in the fore wings starting from radius 3 far back, or about one third distant from base of 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, and new variety of davisi.

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

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.

  • Neotibicen davisi davisi (Smith and Grossbeck, 1907). Quick ID: it has black on its abdomen.
  • Neotibicen davisi hardeni Davis, 1918. Quick ID: it lacks the black on the abdomen, and is only found in Arkansas and Mississippi.

Identification keys by Wm. T. Davis from MISSISSIPPI CICADAS, WITH A KEY TO THE SPECIES OF THE SOUTHEASTERN UNITED STATES. 1

A. Large, heavy bodied species ; head broad, uncus simple, and first cross vein in the fore wings starting from radius 3 far back, or about one third distant from base of 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, and new variety of davisi.

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

Neotibicen davisi hardeni Davis, 1918:

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

Neotibicen davisi davisi (Smith and Grossbeck, 1907):

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

Description of Neotibicen davisi hardeni Davis, 1918 1:

Tibicen davisi var. harnedi new variety, PI. VII, fig. 4.

Type male, Helena, Arkansas, June, 19 16 (K. D. Jacob). Davis
collection.

Allotype female, Rodney, Jefferson Co., Miss.. August, 1917 (O.
A. Hammett). Collection, Miss. Agri. and Mechanical College.

More robust than typical davisi, with broader wings, the first seven marginal cells of the fore wings being clouded much as in Tibicen superba Fitch. The dorsal markings are quite green in color, the central, green, wedge-shaped mark on the pronotum is not sepa- rated from the hind margin, but is confluent with it; the collar is bright green. The dorsal surface is less rusty in appearance than in typical davisi. Beneath the abdomen is greenish, without the “narrow black portion in the center,” as in typical davisi.

Location and song notes 1:

davisi occurs throughout the southeastern states as far north as New Jersey. Its song- is a continuous z-ing of short duration, and is sharper in tone, though not as loud as that produced by the larger, related black species.
