Stonefly Nymphs – The Year-Round Secret
Why Stonefly Nymphs are a must-have:
-
Protein Power: These nutrient-rich nymphs are a primary food source for trout and grayling all year long.
-
Easy Targets: As poor swimmers, they often lose their grip and drift downstream, becoming an effortless "snack" for waiting fish.
-
Bottom Dwellers: Unlike many insects, they don't swim to the surface to hatch; they crawl to the shore. This keeps them in the "strike zone" near the riverbed for their entire life cycle.
J:son Tungsten Stonefly Nymph 5 Olive Brown (#16)
The Micro Stealth Specialist – Amphinemura and Nemoura Imitator The J:son Tungsten Stonefly Nymph 5 Olive Brown in size #16 is a masterfully crafted 12 mm imitation, reinforced with a high-density tungsten core. This "Micro" nymph is designed to replicate the small, earthy-toned nymphs of the Nemouridae family, which are prevalent in cold, clean streams throughout the season.
Why this fly works:
-
Stealthy Depth: In technical water, fish often spook at large, heavy flies. This 12 mm nymph offers a small, non-threatening profile, while the integrated tungsten ensures it sinks rapidly into the "strike zone" near the bottom—even in fast-moving riffles.
-
Biological Accuracy: Small olive and brown stoneflies are the "bread and butter" of a river's ecosystem. The 12 mm profile and mottled Olive Brown coloration provide a perfect "match-the-hatch" solution for these common, everyday food sources.
-
Anatomical Mastery: Even at this miniature scale, J:son’s S5 design maintains perfect anatomical proportions. The segmented wing pads and ultra-fine, flexible legs create a lifelike silhouette and subtle micro-vibrations that convince even the most selective trophy fish.
-
Soft-Body Technology: Constructed from J:son’s signature flexible materials, the nymph has an organic texture. This ensures that when a fish sips in this tiny nymph, it doesn't feel a hard imitation, resulting in longer hold times and better hook sets.
Pro Tip: This is a deadly "dropper" nymph for technical fishing in low, clear water. Use it on a long, fine leader (5X or 6X) to target large grayling and trout that are feeding selectively on small substrate-dwellers. It is also an exceptional choice for "French Nymphing" setups where a slim, heavy fly is required to maintain contact with the riverbed.
