Agent Orange Stonefly

The Agent Orange Stonefly, credited to Todd Ostenson, a skilled guide and fly tyer from Oregon, was developed to mimic the large stonefly nymphs that thrive in the Pacific Northwest’s swift rivers. Ostenson's innovative design combines a bright orange bead head and synthetic materials with the natural profile and movement of stonefly nymphs, creating a pattern highly effective for trout and steelhead. Designed to cut through turbulent water and attract attention in low-visibility conditions, it quickly gained popularity in rivers like the Rogue and Deschutes. The Agent Orange stands out for its ability to balance visibility, realism, and durability, making it a favorite among anglers targeting aggressive fish during stonefly hatches.

Winter Steelhead Secret: When winter flows are high and cold, dead-drift the Agent Orange Stonefly under a heavy indicator in deep runs. Steelhead often hold in slower water and are triggered by the fly’s bold color and undulating legs.
