Morphologies in Tibicen chloromera Cicada Species
Introduction and Objective of this Page
I figured since I have been able to collect some examples of Tibicen chloromera from Connecticut that they as well as other cicada species that I collect in the US should probably be documented.
The introduction and purpose is essentially the same as can be found on the Morphologies in Tibicen lyricen Cicadas page. If you want to read the introduction and objective click here to have a look.
Before we get started, you should familiarize yourself with some terms that we will be using.
Pronotum - Part of the area behind the two big compound eyes that along with the mesonotum make up the thorax.
Pronotal Collar - thin band approximately 2 mm wide (1/16th of an inch) located just below the pronotum and divides the pronotum and mesonotum.
Mesonotum - Area below the pronotal collar but above the abdomen. Front forewing hinges are located against the mesonotum.

Pronotum - Outer edges dark green fading to light green towards the center. Distinct black trianglular shape located medially with 'dear's head" shape located within triangle. Dark bronze pubescence is also noted.
Pronotal Collar - Mostly black with two small distinct brown patches approximately 2 mm wide by 1 mm thick.
Mesonotum - Thick brown patches located to left and right above the wing hinges. McDonalds Arches not distinct. Mesonotum mostly black.
Note: Heavy patches of white pruinosity located where abdomen meets mesonotum.
About Specimen - Specimen was collected from Wethersfield High School in Wethersfield Connecticut on 08/11/05. Specimen mated with Male Tibicen Chloromera example 1 in captivity.

Pronotoal Collar - Mostly black with two large green patches to left and right of shoulders.
Mesonotum - Mostly black with faded brown patches to left and right above wing hinges. McDonalds Arches not distinct.
Note: Heavy patches of white pruinosity located where abdomen meets mesonotum.

Mesonotum - Almost completely black with very faded brown patches located to left and right above wing hinges. McDonalds Arches not distinct.
About Specimen - Specimen was collected at Wethersfield High School, Wethersfield Connecticut on 08/11/05. This male mated with T. chloromera examples 1 and 2 above in captivity. Also one of specimen's forewings was discovered to be torn in places. Probably due t a predatory attack.
