STONE FLIES

These flies are quite common on our western rivers and streams. On the average they are large, meaty flies that are very appealing to trout, but some species are quite small.

The large dark brown or black "Salmon fly" average about two inches in length, and the small yellow stone fly may be one quarter or an inch. All of these stone flies are an important part of the trout's diet, but more so as a nymph, since this fly is largely out of reach to the trout after his transformation into an adult.

Stone Fly Nymph (Black Chinelle body with red or yellow underbelly), Black Horsehair Potts Fly with orange belly and brown hackle. Mormon Girl, Gray Hackle Yellow, Double Renegade.
