This one is throwing me for a loop...

---My thoughts concerning this cicada as they occurred to me---

- According to Dr. Sanborn, there are 7 species of Tibicen in DE (in no particular order):
T. davisi davisi
T. linnei
T. lyricen lyricen
T. lyricen engelhardti
T. Tibicen Tibicen
T. Winnemanna
T. auletes


- From what I'm used to seeing, the legs don't look green enough and the pronotal collar isn't dark enough for a T. tibicen tibicen... So, I'm dropping T. t.t. down a few notches on the list...

- The brown, wide pronotal collar is interesting. It makes me think of T. davisi davisi. However, because I just finished looking at a large number of T. d.d. images last night before going to bed, I'm trying to resist the urge to call it as such. Especially since the head doesn't look quite like a T. d.d.--the eyes are not large enough and the pronotal collar appears to have a definite boundary along the pronotum. Also, the EXTREMELY well developed pruinose spots on the abdominal section next to the mesonotum are NOT something I've seen in T. d.d.---And yet, that's all I can think of.

- The shape of the wing tip is certainly reminiscent of a T. d.d. If the image were clearer and I could tell if the tips of the wings were infuscated (smokey) or not, then that would be of infinite value and I could move forward...

---End of my thought process concerning this cicada---

That's all I've got. I'm kind of flummoxed concerning this one.

Bill Reynolds is going to have to work his magic and pull another rabbit out of the hat for us 'cuz my rabbit is dead.

Cheers

Good call Jimmy, it's a T. tibicen ssp. tibicen!
Tibicen tibicen "Mid-Atlantic Phenotypes"


These cicadas are frequently misidentified due to the skewing of traits typically used as identification markers for the taxon Tibicen tibicen (chloromerus). These populations are often composed of individuals characterized by increased coloration and pattern, green mottling of the pronotal collar and bright reds and greens on the mesonotum. Not implying that similar phenotypes cannot be found across the species' range, there is simply a greater concentration of these types along the Atlantic coast, and certainly given the identification issues they present, are worthy of mention.

And yes Bill...it's a potentially hard one...it is certainly a divergent individual from the expected traits for its taxon.
+ Sanborn's lists for the Tibicen species are not complete....Delaware also has latifasciatus :)

Bill Myers and Bill Reynolds - Thanks for the explanation and sharing your thought process.

Always messin' with us Midwestern folks! LOL

I knew you would be able to pull that rabbit out of the hat! Thank you. Much appreciated.

Also, thank you for the heads-up on T. latifasciatus. I've edited it into my copy of Dr. Sanborn's list and asterisked it with references to you and BugGuide.

Cheers

Beware ...
Some of the specimens of Tibicen chloromerus (still prefer that to Tibicen tibicen) found in the western parts of the range can have green pronotal collars (esp. the females).

editing lists... :)
Huge job. There are so many cicadas and the renges are not well known and often poorly documented. + some of the ranges are questionable when you consider the regions and taxa listed. For instance, one wouldn't expect to find an eastern species in Calif. or a coastal species far inland....

I think (know) there are a lot of errors as well, esp. those based on collections ...consider discolored material, lost labels, and those specimens submitted by collecge students for credit (data & interpretation can be flat out wrong).

That's why I prefer and depend on direct contact with those collecting and/or doing the foot work myself.
