Thank You Joe for your response! Most enlightening and appreciated..
I am a TU Life member but have not transfered my membership south;
perhaps I could make it to a Clinch meeting. Do you regularly attend?
Now as to seeing BWO's on the Clinch about fuve weeks ago... I am not a bug scientist by any means but I've spent a bunch of time fishing eastern olive hatches and these were not sulphurs. This was a sparse hatch and none of the bugs made it off the water, the air outside was in the lower forties and a bunch of the bugs landed in an eddy behind miller's island so I had the opportunity to observe then in hand. very definitely BWO's with correct body and dark dun wings size 16... they were beautiful.
