About this Pattern
Randall Kaufmann's Stimulator is the go-to stonefly attractor pattern for Colorado freestone rivers. The foam-like body and elk hair wing keep it afloat in the roughest water, and the yellow or orange body mimics golden stoneflies and hoppers. It's also a killer hopper-dropper fly.
