This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.
It appears to be a leptocerid but I don't recognize the color pattern. Perhaps the eastern folks will be familiar with the pattern. Given the habitat and a little that I think I see from the wing this may be Oecetis.

Guys,
Leptoceridae...........
1. L.ceraclea (scaly wing sedge)
wing..... color varies from light brown to dark brown, or from light gray to almost black. On many species the wings have 'patches of white hairs and/or pockets of white scales'.
2. L.oecetis (long horned sedge)
wing..... varies from straw yellow to brown
** antenna.... may be extremely long
I would guess this is L.ceraclea based on the 'white hairs ' on the scaly wings!
Ref: Caddisflies, Lafontaine, pg.253
Flyfishing is a state of mind! .............. Q.g.
Nanz - I am looking for the shape of the apical m vein. It is not forked in Oecetis and can be fairly obvious.
As Quillgordon says, Ceraclea usually has very hairy wings. The hairs in your photo have nearly obscured the m vein apex but I "think" it looks straight at the apex. It is just not clear enough to be sure.
I wandered through what I could find of the "leptocerids" on BugGuide and didn't see anything I would say was the same as yours, but there are a couple of other Ceraclea with the obvious white scale hairs. And, I did see what looks like a really neat, and very very rare Limnephilid. It will be good to try and track that down.
I increased the resolution of the second image in hopes it would show "the shape of the apical m vein" but I am not hopeful given how hairy it is. Slightly above and to the right of the center there is a dark "M" shape. The right side of the "M" looks like a branch. I don't suppose that's what you are referring to, is it?
I also am adding one more view.
The images on Bugguide, I was talking about, can be found at http://bugguide.net/node/view/115037/bgimage and http://bugguide.net/node/view/143406/bgimage.
I'm sure any help you could give to the folks at Bugguide would be immensely appreciated.

I knew it would get dirty with you bug guys eventually; it always does. If you do flip it over, Roger will be sure to get out his little red arrows to show us what's what. In all seriousness, great photos. --And, I'm in awe of anyone who can even begin to id caddisflies.
