I'm not sure if this lil'tidbit is gonna come across as "Helpful" or if it's going to hurt somebody's feelings....... But the fish in Taneycomo are highly unlikely to become SELECTIVE on Cicadas. So don't get too hung up on that. The water is clear enough that no SPLAT is needed to "ring the dinner bell", or for them to notice your fly.
The Cicadas might get them looking up, and taking bigger bites though, so don't hesitate to drift a #8 or #6 Stimulator, Royal Wulff, Chernobyl Ant, Oversized Crackleback.....or anything else you can reasonably tie onto 4x or 3x tippet. 👍
