Tibicen? - Neotibicen linnei

I suspect T. linnei

This is a female cicada.

The trace pruinose spots at the base of the abdomen are evident in this specimen & occasionally seen in females of linnei (a rare trait in females of both T. linnei and canicularis). The wing proportions & node position are also suggestive of T. linnei - however, these traits are not unique to linnei and there can be overlap with T. canicularis.

The moderate discoloration (esp. eyes) is an artifact of this insect being dead.

Additional images of the lateral and ventral perspectives would be more revealing.

Other possibilities incl. T. canicularis

Thank you Bill. I have a fron

Thank you Bill. I have a frontal shot as well, but don't like to post many 'dead bug' photos. Let me know if you want me to link it.

ABSOLUTELY Tibicen linnei!

Ooopps......& Wow!...with the lateral and ventral images added it's apparently a MALE!!!....got the species - missed the gender!

I made a bad call (the shriveled up telescoped in abdomen in the dorsal shot looked more like that of a female). The 2nd abdominal segment looked like the 1st...coudn't see the 1st abdominal segment. HOWEVER, That explains the white spots at the base of the abdomen - This is a much more common trait in males of this species than in females.

It looks like this guy died as a late teneral/young adult - it lacks the chalky white pruinosity and has the beginnings of a ventral black stripe on the abdomen (suggestive of it being "young"). However, the strongly bowed wing shape and opercula shape are diagnostic of linnei.

Your addional pic's helped ;)
Got the species, but missed the gender...Oh well :)

Thanks again! Much appreciate

Thanks again! Much appreciate all your effort - I am unable to discern neither species nor gender, so no criticism forthcoming from this quarter! I think this is the first posting of this species from Ontario, though - are they less common than T. canicularis ?

It is the 1st for Ontario and I placed it accordingly :)

GOOD JOB!
It is the 1st for Ontario here on Bugguide and I placed it accordingly :)

T. linnei can be common (and is across from you in NY), but I think it depends on location as of which, linnei or canicularis, is prevalent. Both species can be very locally abundant.

T. linnei seems to be more often associated with deciduous trees while canicularis with conifers, but this is not an absolute.

Please do post it.

Additional pic's don't hurt.
