When the stoneflies are on the move, nothing in your box works harder than a Stimulator — and this size 12 in yellow is the one you want when the naturals are big. Tied with Hareline yellow grizzly hackle and a buoyant Nature's Spirit Stimulator deer-hair wing, it rides high through the roughest pocket water and stays visible at distance, even in glare.

The Stimulator is the ultimate impressionist: trout read it as a golden stonefly, an October caddis, or a hopper that took a wrong turn, which makes it deadly as a searching pattern when no single hatch dominates. That bushy deer-hair wing and palmered hackle also make it one of the best hopper-dropper indicators ever tied — hang a beadhead nymph off the bend and fish two zones at once.

Drift it tight to the banks on western freestones, skate it across riffles for aggressive browns, or use it as your lead fly when prospecting unfamiliar water. If you're only carrying one attractor dry in big-fish water, make it this one.
