Perhaps, but Paraleptophlebia hind wings are characterized by lack of costal angulation, unlike this specimen, which seems to have rather sharply defined costal angulation.

taxon, what is that avatar picture you are using? I've been staring at it and can't make out what it is.

I know there were at least two types of bugs because I caught one that had only two tails...sorta assumed it was probably baetis...??

Taxon, here is the information I entered:

3 tails
#16 (may have been a bit larger and depending on how much, this does change the results)
Uniform color fore wings
Obvious hind wings
left the "other characteristics" blank
flowing water
during daylight
SE US


While ya'll are helping me with my bugs, here's photos of all that I saw (at least all I got pics of)... The VAST majority of bugs were like the last one pictured here for those that want to know what is/was hatching...

Trevor-

Good question. It's the larval head of a Limnephillid (Northern Casemaker Caddisfly), genus Limnephilus as I recall.

What do you think Taxon? They are all so close in appearce, and the truth is PA they all could have been hatching that day.
flyman-

Yes, I agree. Perhaps you missed my post #5 above.

Plateau Angler-

The problem with Attenella attenuata would be that there aren't any in TN. See N. American Mayfly Distribution on my site, and enter TN is the box for State.

Also, you might want to a look at the leading picture in this article I wrote for Hatches Magazine two years ago. I think you'll find a striking resemblence to your specimen. Another thing that made me lean toward Ephemerella subvaria is that it's the earliest emerging of the Ephemerella species you have in TN.

Taxon I did miss your post, thanks for the confirmation of the info. Attenella attenuata (McDunnough 1925) have been documented in Great Smoky MT Nationa Park.

http://www.discoverlife.org/nh/cl/GS...cts_GSMNP.html

I think a few more detailed studies of aquatic insects has been done in the park than the rest of the region. I have noticed in the past several species left off of the USGS site present in places not indicated on their map.

http://www.npwrc.usgs.gov/resource/d...mfly/index.htm

BTW-I would like to complement you on your site. Well done, lots of great info in a format that the average person can comprehend.

flyman-

Thanks for sharing that information, and also for your kind words concerning my website. With regard to Attenella attenuata, I suspect they were in the N. Carolina part of the SMNP, as opposed to the Tennessee part, however. In any event, whatever source one uses for mayfly distribution, it will always be incomplete to one degree or another.
