JHFLYCO Stonefly Life Stages Assortment

The Stonefly Playbook in a Box If you want to take the guesswork out of stonefly fishing, we've built a loaded fly box that covers the full lifecycle — proven patterns at every stage, balanced sizes, and the species coverage that matters most on Western water. This hand-picked assortment combines realistic nymphs, rubber-leg searching patterns, and adult dries to cover the full stonefly year — from January nymph fishing through the salmonfly hatch in May and June. Inside, you'll find lifecycle staples like Kaufmann's Stonefly Nymph, Mark's Stonefly, Beadhead Flashback Stonefly, Beadhead Micro Golden Stone, and Southfork Stone, plus rubber-leg workhorses like the Rootbeer Yuk Bug Conehead and adult dries like the Black Stimulator and Golden Stone — all balanced across sizes 6–12 to match the hatch and the season. Each fly is mounted in our JHFLYCO Foam Fly Box in Orange — a high-visibility foam-slit box built to hold larger stonefly patterns securely and keep them organized through long days on fast water. The orange color makes it easy to spot in your pack or on a tailgate, and the slim profile fits cleanly in chest packs and sling bags. Included Patterns 3 of each pattern – 24 flies total Kaufmann's Stonefly Nymph – Black (#8): The classic realistic salmonfly nymph — segmented body, biot tails, and a weighted underbody that gets to the rocks where mature nymphs live. A Western standard for decades. Mark's Stonefly – Brown (#6): A modern realistic golden stone with a soft hackle collar that pulses naturally in the current — particularly effective when fish get selective during the pre-hatch window. Southfork Stone (#6): A specialized nymph designed for the South Fork of the Snake and similar Western rivers; weighted body with subtle flash for transitional water. Beadhead Flashback Stonefly Nymph – Black (#10): Adds a flashback wingcase to the standard black stonefly silhouette — catches light, triggers strikes, and gets down fast in slightly off-color water. Beadhead Micro Golden Stone (#10): The smaller, lighter golden stone option for mid-season and dropper rigs — perfect as a second fly behind a heavier anchor or a trailer below a foam dry. Conehead Rootbeer Yuk Bug (#6): The dual-purpose searching nymph that fishes equally well for salmonfly and golden stone water; conehead drops it deep, flash collar adds attraction in stained flows. Stimulator - Black (#12): The traditional salmonfly attractor — hair wing, palmered hackle, and a realistic adult silhouette that produces when fish refuse foam patterns in clearer water or slower seams. Golden Stone (#6): A realistic adult golden stone dry for picky fish in slower water — back eddies, glassy seams, and spring creeks where foam attractors get refused. Features JHFLYCO Foam Fly Box Included (Orange): Durable foam-slit fly box with high-visibility orange color for easy locating in your pack Complete Lifecycle Coverage: Six nymph patterns plus two adult dries — every stage from juvenile to egg-laying flight Both Major Species: Balanced selection covering both salmonfly (Pteronarcys) and golden stone (Hesperoperla/Calineuria) profiles Proven Across the Season: Patterns and sizes that produce from winter pre-runoff nymphing through the summer dry fly window Why Choose the JHFLYCO Stonefly Life Stages Assortment? Stoneflies are the biggest, meatiest insect in most Western rivers — and the food source trout build their feeding year around. The famous salmonfly hatch only lasts a few weeks, but stonefly nymphs are crawling along the riverbed for one to three years before they emerge, making them a year-round eating opportunity that most anglers underfish. This curated assortment is built to help anglers cover stoneflies through every productive moment of their lifecycle, whether you're nymphing deep in pre-runoff, fishing the banks tight during the pre-hatch migration, or switching to high-floating foam dries when the egg-laying flights start. From the Madison to the Henry's Fork to the Big Hole, this all-in-one stonefly system helps you stay confident, fish efficiently, and make every drift count.
