Better IDs for E.A. Seguy Cicada Illustrations

The NCSU Libraries Rare and Unique Digital Collections website recently reminded the us of artist Eugene Alain (E.A.) Seguy’s insect illustrations. Seguy created these illustrations in the 1920’s, and as you might imagine, some of the cicada names cited in the notes for these illustrations have changed. Names typically change when cicadas are reclassified due to discoveries about their biology, or when we realize that someone else had actually named them earlier than the namer currently given credit.

Here are the two illustrations, the accompanying identification, and corrected identifications.

Illustration:

Accompanying identification:

1. Tacua speciosa. Indes; 2. Polyneura ducalis. Indes Or.; 3. Cicada saccata. Australie; 4. Cicada fascialis. Siam; 5. Tozena melanoptera. Indes Or.

Corrected or expanded identification:

  1. Tacua speciosa. This is correct, although there are two subspecies of T. speciosa, I’m going to guess it is Tacua speciosa speciosa (Illiger, 1800) based on the location.
  2. Polyneura ducalis. This is correct. Polyneura ducalis Westwood, 1840.
  3. Cicada saccata. This is now: Thopha saccata (Fabricius, 1803).
  4. Cicada fascialis. This is now: Cryptotympana facialis facialis (Walker, 1858). Update: David Emery says this might be a Cryptotympana acuta (Signoret, 1849).
  5. Tozena melanoptera. Close enough. Tosena melanoptera melanoptera (White, 1846). There are a few unnamed subspecies.

Accompanying identification:

1. Goeana festiva. Indes; 2. Zammara tympanum. Amérique du Sud; 3. Goeana ochracea. Indes; 4. Phenax variegata. Brésil; 5. Hemisciera maculipennis. Amazone

Corrected or expanded identification:

  1. Goeana festiva is actually Callogaeana festiva festiva (Fabricius, 1803).
  2. Zammara tympanum. This is correct. Zammara tympanum (Fabricius, 1803).
  3. Goeana ochracea is way off. It is a Talainga binghami Distant, 1890.
  4. Phenax variegata is not a cicada, is it a fulgoroid planthopper, but the id is correct.
  5. Hemisciera maculipennis is correct. Hemisciera maculipennis (de Laporte, 1832) aka the “Stop and Go” cicada, because its colors resemble the colors of a stop light.

2015 Periodical Cicada Emergences

Filed under: Brood IV,Brood XXIII,Magicicada,Periodical Stragglers — Dan @ 1:06 am

There will be two major periodical cicada emergences in 2015. We’re less that 2 months away!

2015 BROOD IV AND XXIII

Brood XXIII, the Lower Mississippi Valley brood:

This brood of 13 year Magicicada will emerge in Louisiana, Mississippi, Arkansas, Tennessee, Missouri, Kentucky, Illinois, and Indiana. Brood XXIII features all four 13 year Magicicada species M. tredecim, M. neotredecim, M. tredecassini and M. tredecula.

When they’ll emerge depends on the weather. A cool spring will mean the emergences will start later in the spring. Regardless of the weather, the emergences will begin in the Southern-most states, sometime in late April or early to mid May.

Brood XXIII should, depending on the weather, start emerging in less than two months; some time in late April in Louisiana.

Brood IV, the Kansan Brood:

This brood of 17 year Magicicada will emerge in Texas, Oklahoma, Missouri, Kansas, Nebraska, and Iowa. Brood VI features all three 17 year Magicicada species M. septendecim, M. cassini, and M. septendecula.

Brood IV should start emerging in early May.

Brood IV and XXIII won’t emerge in the same year again until the year 2236. The only state that features both Brood XXIII & IV is Missouri, but the areas where they emerge do not overlap.

Stragglers:

The best bet for Stragglers will be Brood VIII (17 year cicadas emerging 4 years early) & XIX (13 year cicadas emerging 4 years late). There is also a chance for III (17yr/1 year late), V (17yr/1 year early), and XXII (13yr/1 year late). Visit our brood page, to see the states where these stragglers might emerge.
