The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
Too bad there are no pics of Potamanthus (golden drake). They may be extinct (siltation and acid rain?)...talked with Charlie Meck about that a few years ago.
Kurt got some clean up to do on this thread I would think. I don't think Iso's were mentioned.
by the way, i think the picture is Anthopotamus distinctus
I would suggest the thread be retitled by CraigK, as the Isonychia bicolor title is rather confusing.
