Sulphurs are in full swing from April through November, you’re going to need several dozen or more of these in your box. When I am tying these, I will run a drop of zap-a-gap down my thread base before wrapping my biot forward making it a much more durable fly. You will want to keep plenty of frogs fanny around during sulphur hatches to keep these flies riding high on the top.

Blue wing olives are the most prevalent starting in the late fall through the early spring. They range in size from #18-24. I find that most days I can get away with a #20 without a real prevalent hatch. This fly will catch fish for you just about year round. It is even more important to keep this fly liberally coated with frogs fanny so that you and the fish can see it. You can just about bet that on any given day on the South Holston or the Watauga River there is going to be blue wing olives hatching somewhere.
