Flies are often tied more for the fisherman than the fish. We can't help ourselves, colorfully decorated hooks are appealing. When I look into my flybox the flashy ones draw my attention and I convince myself that they will do the same with trout. Little midges continually fight for my recognition yet they they deliver time and again. None more than the WD-40. It is little more than thread, dubbing, and wood duck feather and it needn’t be anything else. Trout love this fly.
