Stimulator - Orange

Stimulator - Orange

The Stimulator is one of the most iconic and versatile attractor dry flies ever tied — a high-floating, heavily hackled pattern that imitates stoneflies, grasshoppers, and large caddis all at once, making it a go-to searching pattern on freestone streams and pocket water throughout the West. The orange version is particularly effective during golden stonefly and October caddis hatches, when trout are keyed on large, orange-bodied insects drifting on the surface. Its elk hair wing and palmered hackle keep it riding high and visible in fast, turbulent water, while its bold silhouette triggers aggressive, confident strikes from trout that are actively looking up.
