Mustachio Stone Fly Nymph Tying Kit

Every Great Stonefly Nymph Starts With the Right Materials

There's a moment every tier knows — you've got the vision for a pattern in your head, but you're missing that one material, or the color's slightly off, or the bead's the wrong size. This kit exists so that moment never happens with the Mustachio Stone.

Everything you need to tie the exact pattern from our tutorial — sourced, matched, and bundled together — is right here. No substitutions, no guesswork, no hunting through six different product pages to piece it together. Open the kit, sit down at the vise, and tie.

Why This Pattern Deserves a Spot in Your Box

Stoneflies are famously poor swimmers. When they lose their grip on the riverbed, they don't fight the current — they curl up and tumble, helpless, until they catch onto the next rock or log. That vulnerable, out-of-control drift is exactly what triggers aggressive eats from trout, and it's exactly what the Mustachio Stone Fly Nymph is built to imitate.

This isn't just another stonefly pattern, either. The loop-spun zonker thorax gives it a pulsing, breathing quality other patterns don't have — even mid-drift, even when the current slows. Add a fast-sinking tungsten bead to get it down into the heavy water where the naturals actually live, and you've got a pattern that's proven itself far beyond typical stonefly water thanks to its buggy, can't-miss silhouette.

What's In This Kit

Every material below is included — measured, matched, and ready for the vise:

Built to Fish, Not Just Sit in a Box

Every material here earns its place. The tungsten bead punches the fly down fast into heavy currents. The squirrel dubbing builds a buggy, translucent abdomen that catches light underwater. The loop-spun zonker thorax pulses on its own, giving the fly life even on a dead drift. And the SRF legs and antennae add the mobile, kicking motion that sells the illusion of a nymph tumbling helplessly through the current.

Tie it once, and you'll understand why this one's earned a permanent spot in western stonefly boxes — and plenty of boxes far outside stonefly country, too.
