The Caddis Fly: Oregon Fly Fishing Blog

The yellow stimulator is one of the most popular flies in the West and it’s a great imitator for a Golden Stonefly. It’s got excellent floatation and you can hang a good sized nymph off of this fly. We tie the stimulator for speed and durability. This is a heavily dressed pattern and it fishes all summer long on the Deschutes, McKenzie and Willamette rivers.
