Tibicen tibicen (chloromerus) - 100%

Here in the eastern US, with regards to molts belonging to the Genus Tibicen, the dark brown-black base of the wing pad is diagnostic in this single species.

Related taxa exhibit wing pads/bases with a uniform color as seen over the rest of the exoskeleton.

+ Tibicen tibicen is very common in that part of PA.

Really?

I never knew the dark brown base of the wing pad is a characteristic only of the T. tibicen. Thanks for the info!

Of the many nymphs collected & reported

Of the many T. tibicen nymphs collected & reported, this trait seems to hold true. Some other taxa may show slightly darker tans to light brown bases but not so dark as seen here.

NOTE: T. tibicen (chloromerus) forms in the "australis" range & intergrade zones may be subject to differ.

On another note, there are a few folks working on a key/guide to Tibicen molts. As a rule, I can tell, but linnei, canicularis and some of the pruinosus group can be difficult given size overlap and geo. variations.

If you have addiitonal observations or examples, I am interested. Most of what we have in print is older lit.

Cheers

I'm actually...

...quite interested in the full range of T. tibicen. Most range maps do not show the true extent of this species population. Scattered populations are spread in multiple parts of "unmarked" areas. I have heard quite a few individuals far away from where the range was marked on the map on this particular site: http://www.songsofinsects.com/iframes/cicadas/cicadas.html

Eastern Tibicen species

Jimmy,

I'd be glad to share my personal info on any of the taxa here on BG. I have been collecting cicadas for years and have a large reference collection, notes and contacts.

Cheers,
bill

Few species are confused with T. tibicen, but it happens!

Audal reports for members of the linnei complex and even dorsatus have contaminated the audal reports & distr. for this species.

I do know tibicen nominate extends into e. TX and the eastern fringe of the plains n. into the Great Lakes region of Canada. Recent reports place it in ne US in CT, RI, & e. & s. MA.

Subspecies australis replaces this taxon in the s. 1/3 of GA and FL peninsula. This ssp. also seems to be quite different and exhibits limited blending in a narrow zone of interface with the nominate form (see Info for australis and assoc. hybrids).

Cast of exoskeleton of a Cicada

Either it is a lyric cicada (Tibicen lyricen) or a Northern dog day cicada (Tibicen canicularis).

Cicada

This is the cast-off exoskeleton of a cicada. I don't know which one, but at this time of year it may well be a Tibicen species.
