Is this perhaps a Swamp or a Dogday Cicada?

Tibicen tibicen (Tibicen chloromera) female
It's definitely a Tibicen tibicen (Tibicen chloromera) female.

Moved from Swamp Cicada.


Tibicen tibicen australis
Refer to the images of male T. latifasciatus, as this is the species in the pruinosus complex found in peninsular Florida. Additionally, females of T. latifasciatus possess two bold, well defined white bars at the base of the abdomen ("gill slit-like" pruinose bars). Although T. tibicen australis has a green pronotal collar, it does not have the 2 distinctive lateral white bars held by T. pruinosus latifasciatus.

Need a New Page
I would suggest a new category for T. tibicen var. australis on Bugguide. This southern species of T. tibicen has enough key identifying factors to distinguish it from regular T. tibicen. Just like T. lyricen var. virescens.

Tibicen Tibicen australis

I will also be adding another variant of T. tibicen (nr. australis - ??) from South Alabama that is also different in appearance.

Tibicen pruinosa
I don't know the Florida cicadas, but the strongly contrasting white venter and pointed wing tips indicate T. pruinosa. And yes, T. pruinosa IS recorded from FL.

Tibicen tibicen (chloromera) "australis"
I am originally from Ocala, Marion Co., Florida immediately to the south of Alachua Co. I agree, Florida cicadas can present a canundrum when it comes to identification since several Floridian Tibicen species deviate in color from their more northern conspecifics (Case in point T. lyricen and T. tibicen). Although there are records for "T. pruinosus" (Tibicen latifasciatus) in Florida, it has been my experience that "Tibicen tibicen" (Tibicen australis) is a little more prevalent (noting that neither species is widespread nor very abundant that far south unless you happen upon the right habitat/spot). However, I do vividly recall "swamp cicadas" with their rapid early to mid-morning call - always a prize to catch as a child. Unlike the T. tibicen specimens in other parts of the southeast, Gulf coast varieties often lack the black pronotal collar and heavy black pigments on the pronotum and mesonotum, hence may superficially resemble some of the other Tibicen species in coloration. I have several specimens from Marion, Levy and Citrus Counties, and a few south Alabama specimens (nr. australis?), most of which, based on color alone look little like T. tibicen here in NC (= more inland & northern populations). Much like the individual in the photo, members of the Tibicen tibicen complex have "bright mint-green" legs, a clean white venter and usually appear to be a little more compact and "hump-backed" than do members of the pruinosus group; hence I suspect this image is a female Tibicen tibicen "australis".

Definately Tibicen genus
It's very difficult to identify most Tibicen genus cicadas down to species. One really has to be familiar with the types of Tibicens in their area of the US. Even within a species there can be varying color morphs.

The term "Swamp Cicada" seems to signify T. chloromera cicadas, it is in my opinion bad nomenclature as T. chloromera can be found in many different environments not just swamps.

Same with "Dog Day Cicada". While it seems to signify (at least from what I see in Bugguide) T. canicularis, the term should be used for the Tibicen genus as a whole. As Tibicen cicadas are the most common cicada throughout the US in summer; however, T. canicularis' range while wide spread does not appear in many areas of the US.

I can tell you that the cicada image is definately a female judging by the shape of the sternites and tergites at the tip of the abdomen.
