When winter settles in and most hatches fade, two insects keep trout feeding: midges and Blue-Winged Olives. These tiny bugs dominate cold-water fishing from December through March, and if you're tying flies to match them, dubbing selection makes all the difference.
Midges emerge year-round, even on the coldest days. BWOs show up sporadically when conditions are right—usually on overcast afternoons when the temperature nudges above freezing. Both require precision tying in sizes 18-24, and the right dubbing blend creates the slender, segmented bodies that trigger strikes from selective winter trout.
Winter Fly Tying: Quick Tips for Success
Tying flies for winter trout requires precision and the right materials. Keep these essentials in mind:
- Size down: Winter patterns run 18-24 for midges and BWOs—stock small hooks and fine thread
- Blend natural and synthetic dubbings: Hare's ear adds texture, Ice Dub and SLF provide flash and consistency
- Test sink rates: Drop finished flies in water to ensure nymphs and emergers descend naturally in slow currents
- Use dubbing loops: Create tight, evenly tapered bodies on tiny hooks without bulk
- Add tungsten beads: Pair your dubbing with small tungsten beads for quick-sinking winter patterns
- Focus on olive, black, and red: These colors dominate winter midge and BWO hatches across most tailwaters
- Keep profiles slim: Winter trout are selective—avoid over-dubbing on small patterns
- Incorporate eco-friendly synthetics: Recycled SLF and sustainable materials perform well in pressured water
Why Dubbing Matters For Winter Fly Tying
Winter trout are less active. They're holding in slower currents, conserving energy, and scrutinizing every morsel before committing. That means your flies need to look right—not just close enough.
Dubbing excels at imitating the translucent, segmented bodies of midge larvae and emergers. Natural dubbings like hare's ear and rabbit fur add subtle texture and bugginess. Synthetics like Ice Dub and SLF Prism provide consistency and that critical flash in low-light winter conditions. Blending the two often produces the most effective patterns, creating flies that sink naturally and move like the real thing.
Midge Dubbing Blends That Catch Fish
Midges are the backbone of winter fly fishing. Black, red, and olive dominate, but don't overlook variations in shade and sparkle.
Black Midge Blend
Mix Hare's Ear Dubbing with a touch of Ice Dub for subtle flash. This combination works exceptionally well on Zebra Midges and simple pupa patterns. The hare's ear provides buggy texture while the synthetic adds just enough sparkle to get noticed in murky water or low light. Try Hareline Ice Dub in UV Black—it's become a go-to for many tyers.
Olive Midge Blend
Combine Superfine Dubbing in Olive with SLF Prism for translucency. This blend shines on Griffith's Gnats and midge pupae where you want a fly that floats in the film or hangs just beneath the surface. Wapsi Superfine Dubbing offers fine, easy-to-dub fibers that float well and create slim profiles on small hooks.
Red Midge Blend
Blend Rabbit Fur Dubbing with a hint of red Antron for blood midge imitations. When trout key on chironomids with that distinctive red coloration, this blend delivers. Hareline Rabbit Dubbing provides soft, absorbent bodies that sink naturally and hold their shape after multiple fish.
For 2026, consider incorporating eco-friendly synthetics like recycled SLF. These materials perform well and align with sustainable tying practices—something that matters more in pressured tailwaters and spring creeks.
BWO Dubbing Blends for Winter Hatches
Blue-Winged Olives hatch sporadically through winter, often on overcast days when the air temperature climbs a bit. Focus on olive and gray tones for nymphs and emergers like the RS2 or Baetis patterns.
Olive BWO Blend
Superfine Dubbing in Blue-Winged Olive mixed with Callibaetis creates a custom grayish-tan hue that nails the subtle coloration of winter BWOs. Nature's Spirit Fine Natural Dubbing provides authentic texture with enough guard hairs to suggest legs and gills without overwhelming small hook sizes.
Dark Tan BWO Blend
Hare's Mask Dubbing blended with mahogany SLF works exceptionally well on Pheasant Tail variants and thorax-style nymphs. Our Premium Hare's Mask includes those stiff guard hairs that add lifelike movement underwater.
Custom Gray Blend
Mix SLF with pink and mahogany accents for a Hendrickson-like appearance that also works for darker winter BWO nymphs. SLF Prism Dubbing delivers consistent color and texture across multiple flies, which matters when you're tying a dozen size 20 patterns at the bench.
Tying Tips for Winter Success
Start with a dubbing loop for tight, evenly tapered bodies. Twist your blend onto waxed thread, then pick out fibers with a bodkin for added bugginess. Test flies in water to make sure they sink naturally—winter nymphs and emergers need to get down quickly in slow currents.
For added weight, pair these dubbing blends with tungsten beads. Our tungsten bead collection offers a range of sizes and colors to match your pattern needs without overpowering tiny flies.
