Ducktail BWO
It's BWO time here in Montana. Right now. Due to unseasonally warm early weather the rivers are cloudy. But not blown out. And the flies don't care. They're hatching. The fish and swallows are eating them too. The most effective rig is a BWO dry fly (of some kind) that floats well, with a 12-18" tippet tied to the bend of the dry fly hook, trailing a tiny soft hackle wet fly of some kind. You'll catch fish on both flies. But mostly on the wet fly. I tied this one with a gray wing because that's what the naturals have. But in practice I like to use a whiter wing so it's easier to see. Rocky Mountain Baetis are tiny mayflies. Size 18 at the very biggest. Most are a lot smaller than that. This one's tied on a #22 DaiRiki 135. Three materials: CDC, duck flank and Zelon. 14/0 thread.
