How to Tie the Easiest Stonefly Nymph

The Bare Bones Stone: A Simple, Effective Stonefly Nymph

If you’ve tied a stonefly nymph, you know they can be complicated. Rubber legs, biots, shellbacks, wing cases, multiple dubbing blends, and dozens of steps can make filling a fly box feel like a chore.

The truth is, trout don’t always need that level of detail.

The Bare Bones Stone is the pattern I tie when I want a durable, heavy stonefly that catches fish without spending fifteen minutes at the vise. It takes less than five minutes to tie, sinks quickly, and has become one of my confidence flies for Euro nymphing.

In this tutorial, I’ll show you exactly how to tie it and explain why it has earned a permanent spot in my fly box.

Why the Bare Bones Stone?

A stonefly nymph is typically large and complicated, but I created the Bare Bones Stone to keep things minimal. This pattern is quick to tie, uses very few materials, and is effective in a variety of sizes. Stoneflies don’t always have to be huge; I tie these from size 10 down to 14, using slotted tungsten beads between 3.0 mm and 4.0 mm for weight. This lets me quickly fill a box and always have a reliable stonefly nymph pattern on hand for a range of water conditions.

Additionally, the Bare Bones Stone is highly versatile. You can mix up the dubbing colors to create different variations, or change the leg colors to add that little extra “trigger” trout often go for.

Fishing the Bare Bones Stonefly nymph

I fish the Bare Bones Stone almost exclusively as the point fly on my Euro nymphing rig when faced with heavy riffles or fast runs. The heavy tungsten bead helps get the rig to the bottom quickly while providing enough weight to keep direct contact with my flies throughout the drift. That allows me to fish a smaller, more natural pattern on the dropper when I think trout are feeding selectively.

Although I often use it as an anchor fly, don’t overlook it as an attractor. Plenty of trout have eaten the Bare Bones Stone instead of the smaller fly above it. The slim profile, subtle movement from the rubber legs, and quick sink rate make it an effective searching pattern in pocket water, riffles, and deeper runs. If I’m unsure what trout are feeding on, this is often one of the first flies I tie on because it gets down fast and consistently produces fish.

How to Tie the Bare Bones StoneFly Nymph

Here’s the step-by-step breakdown of how to tie the Bare Bones Stone. If you’re a visual learner, check out the video where I show the entire process from start to finish.

Materials You’ll Need:

• Hook: Firehole 570 Jig Hook (Size 8, 10, or 12)
• Bead: Firehole Slotted Tungsten Stone
• Thread: UTC Thread
• Body: Hare’s Ear Dubbing
• Tail & Legs: Waspi Sili Legs
• Ribbing: UTC Ultra Wire (Medium)
• Thorax: Golden Brown Dubbing
• Wing Case: Loon UV Fly Finish-Black

Step-by-Step Instructions:

1. Load the Hook: Place a jig-style hook in your vise. I’m using a size 12 with a 3.8 mm slotted tungsten bead. You can go up to a size 10 or down to a size 14, depending on your preference.
2. Start Your Thread Base: Begin wrapping UTC 70 thread just behind the bead and stop before the hook bend. Thread color isn’t too critical here since it’ll be covered.
3. Add the Tail: Tie in a single strand of rubber leg material at the tail, separating it into two sections. Secure with a few turns of thread, then wrap back to the bead.
4. Insert the Wire: Slide a piece of gold Ultra Wire into the bead slot for ribbing. This will also add some segmentation and weight.
5. Dub the Body: Create a thin dubbing noodle with light hare’s mask dubbing. Apply small amounts evenly to form the body.
6. Rib the Fly: Counter-wrap the Ultra Wire over the dubbed body to create segmentation. This also adds durability to the fly.
7. Build the Thorax: Use Golden Brown dubbing to create a small thorax behind the bead. Don’t overdo it—this fly is meant to stay slim.
8. Add the Legs: Tie in a long strand of Sili Legs on one side of the fly. Swing the material around the front of the bead and tie it on the other side to create a loop.
9. Finish the Thorax: Apply another small layer of dubbing to cover the front of the thorax. Use a whip finish to secure your thread, hiding it under the dubbing.
10. Form the Legs: Snip the loop in the middle to create two legs on each side of the fly, then trim them to your desired length.
11. Final Touch: For the wing case, add a drop of black UV coating over the thorax. If you don’t have black UV, use a Sharpie and cover it with clear UV.

Why This Pattern Works

The Bare Bones Stone is effective for several reasons. First, its simplicity means it imitates the essential features of a stonefly nymph without getting too bulky. Second, the rubber legs provide that lifelike movement that can trigger strikes. Lastly, the use of heavy tungsten beads ensures it gets down quickly to where the fish are feeding.

The Bare Bones Stone proves that effective flies don’t have to be complicated. It isn’t meant to win a fly tying competition. It’s meant to catch trout. If you’re looking for a fast, durable stonefly pattern you can tie by the dozen, give this one a try.
