Various Megatibicen and Neotibicen compared

It is possible to identify Tibicen just after they have molted

Paul Krombholz has come through with an awesome guide to identifying Tibicens just after they have molted. Click the image below for an even larger version. Note that the genus of these cicadas has changed to either Megatibicen or Neotibicen — notes below.

Paul Krombholz's image of recently molted and adult cicadas compared

Notes on the species from Paul:

N. pruinosus [formerly T. pruinosa]—Newly molted adult has darker mesonotum (top of mesothorax) than the very common T. chloromera. Abdomen is a golden orange color. Older adult has dark olive on lateral sides of mesonotum, lighter green below the “arches”.

M. pronotalis (formerly walkeri, marginalis)—Quite large. The reddish brown color can be seen on the mesonotum of newly molted adult. Older adult has solid green pronotum (top of prothorax) and red-brown markings on sides of mesonotum. Below the “arches” the mesonotum color can range from carmel to green. Head is black between the eyes.

N. tibicen [T. chloromerus, T. chloromera]—has large, swollen mesonotum, quite pale in a newly molted adult and almost entirely black in an older adult. Individuals from east coast can have large russet patches on sides of mesonotum. The white, lateral :”hip patches” on the anteriormost abdominal segment are always present, but the midline white area seen in my picture is sometimes absent.

N. davisi—Small. This is a variable species, but all have an oversized head which is strongly curved, giving it a ‘hammerhead’ appearance. Newly molted individuals are usually brown with blueish wing veins that will become brown, but some have more green in wing veins. Some may have pale mesonotums that will become mostly black. Older adults vary from brownish to olive to green markings on pronotum and mesonotum.

M. figuratus [formerly T. figurata]—a largish entirely brown cicada. Newly molted adult has a pink-brown coloration with some blueish hints. Older adult has chestnut-brown markings and no green anywhere. Head is not very wide in relation to the rest of the body. The small cell at the base of the forewing is black.

M. auletes—a large, wide-bodied cicada. Newly molted adult is very green, but the older adult loses most of the green, usually retaining an olive posterior flange of the pronotum. The dorsal abdomen of the adult has a lot of powdery white on the anterior and posterior segments with a darker band inbetween.

Late cicada season in the U.S.

Filed under: Paul Krombholz,Tibicen — Dan @ 6:23 pm

Cicada Mania contributor Paul Krombholz heard a cicada just a few days ago.

On Nov. 21st the temperature got up to 80 and I heard a T. figuratus [formerly T. figurata] singing. This is by far the latest cicada song I have heard in the Jackson, MS and surrounding area. We have already had several frosts. Usually I hear the last song the first week of November.

Cicadas in late November in the U.S.A. — that’s remarkable.
