Stimulator, Orange

The Orange Stimulator primarily imitates adult stoneflies, especially the Salmonfly (Pteronarcys). Its bushy hackle and vibrant orange body help it float high in fast water and draw aggressive strikes during large stonefly hatches.

History:
Designed by Randall Kaufmann in the 1980s, the Stimulator was created to float like a cork and be visible in fast currents. The orange version is the go-to during Salmonfly hatches in the West, especially on rivers like the Madison, Henry’s Fork, and Deschutes.
