Collection: Stoneflies

Stock up on premium stonefly patterns at Glenwood Springs Outdoors—essential for matching the large stonefly hatches that drive big trout feeding frenzies in Colorado's rivers. Our selection includes top imitations like Pat's Rubber Legs, Girdle Bugs, Jimmy Legs, Black Stone, Golden Stone, Yellow Sally, and Kaufmann's Stone in sizes #4–#12, with weighted beadheads, rubber legs, and durable dubbing for realistic movement and quick sink rates.

These stonefly nymphs and dry flies shine during spring runoff and early summer on the Roaring Fork River (heavy stonefly drifts in fast water), the Frying Pan tailwater (smaller Yellow Sally hatches), and the Colorado River's rocky pockets—perfect for high-sticking, swinging, or indicator nymphing when trout key on migrating nymphs or egg-laying adults.

Trusted by local guides and anglers in the Roaring Fork Valley, our stonefly flies offer lifelike profiles, snag resistance, and strong hooksets in Gold Medal conditions.
