Originator: Legends vary on the exact origins of this pattern, but modern literature attributes it to Pat Bennett, of Hyde Outfitters, Island Park, ID
Hook: 3x long Nymph Hook. Size 4 – 12.
Weight: This can be tied either weighted with lead or non-lead wire, or unweighted for shallow water applications.
Thread: Uni 6/0, brown or your own favorite.
Tail, Legs, and Antennae: MFC Sexi Floss, Medium (brown). Switch it up with MFC Barred Sexi Floss, Medium (brown, copper, or golden yellow) for a great look.
Body: Medium Chenille, brown. Drop down to small chenille for the smallest hook sizes.
Notes: In one word: Essential. Nearly all of our local rivers have significant populations of golden stones, salmonflies, skwalas, and/or nocturnal stoneflies thanks to clean, well oxygenated water. Regionally, this pattern, with its size, color, and weight variations, can be fished effectively 365 days a year. That is because the larger stonefly species spend multiple years in the nymphal stage, making them always available to the trout, even immediately after the year’s primary hatch. Fish it weighted and deep with a smaller dropper during winter and off hatch times. Fish it shallow and unweighted, perhaps as a dropper off a big dry, when the hatch is imminent and the stonefly nymphs are migrating to shore. Really, just fish it. The advantage to tying your own here is that you can mix up the colors and weights. We like to use a different color thread on the weighted vs. unweighted ties so we can tell them apart in the flybox.
