Resting flush on the surface, gives excellent representation of these common stoneflies when at rest.
CDC Yellow Sally (fluttering)
A higher floating imitation that is particularly appropriate when the insects are active on the surface or on quicker currents.
CDC Tailwater Special
When we first designed this pattern it was intended specifically to imitate fluttering stoneflies. The fly is so versatile however that calling it a stonefly falls far short of describing the many insects it can imitate. It is a high-floater with tremendous visibility and is readily taken as a reasonable imitation of numerous aquatic and terrestrial insects. It is hard to beat as a searching fly while wading or floating. Tied with Cul-de-Canard, elk hair, stiff cock hackle and peacock, it is close to being the perfect all around dry fly.
