Ed Ward's large-profile, sparsely dressed swing-fly concept for salmon and steelhead, now tied on shanks and tubes in many colors and material systems.
Size range
No universal size; match the exact form, target, line, casting room, and regulations
Common colors
natural olive or sculpin tones, black and blue or purple, pink, red, cerise, or orange, chartreuse accents
Imitates
large suggestive swimming prey, sculpin-like or other intrusive prey impression, large salmon or steelhead attractor
How to recognize it
Treat Intruder as a construction family, not one fixed recipe. Supported front and rear material stations create a broad moving silhouette around a sparse central body. Weighted eyes, a shank or tube, and a separate or trailing hook system are common, but station count, support, hook, chassis, weight, size, and materials vary and must be labeled.
Scott Howell's historical account identifies Ed Ward as the originator of the Intruder concept for king salmon and documents its evolution among Pacific Northwest steelhead tiers. Modern shank, Waddington, and tube forms retain the broad sparse-station idea but are not one identical recipe.

Pink/red Intruder
Exact source-labeled pink/red Intruder. It demonstrates a bright two-station silhouette; the photograph does not establish water conditions, hook legality, or a universal material recipe.

Look for
A sparse central body, front and rear flared mobile materials, and a bright eye form a readable exact side profile.
Use these tips as a starting point. The river, depth, insects, and fish behavior still decide the final presentation.
01
Why it works
Stiff support behind long sparse hackles creates a broad silhouette with less water-holding material, helping the fly sink, swim freely, and remain castable.
Front and rear stations hold moving fibers away from the central body so the profile stays large without being dressed solid from end to end.
Weighted eyes, line density, cast angle, and mends can establish depth while the sparse body resists lifting as quickly once the swing comes under tension.
02
When to use it
When swinging for salmon or steelhead in water where a large moving profile, the available casting room, and the angler's tackle support the exact fly.
Choose natural, dark, or bright colors from water clarity, light, local practice, and fish response rather than treating one photographed color as universal.
Use a tube, shank, weighted-eye, or lighter form only after checking current speed, desired depth, line system, trailing-hook rules, and target-species regulations.
03
How to fish it
Select sink tip, fly weight, and cast angle for the lane, then cast slightly upstream and make a substantial upstream mend so the fly can descend before tension.
Add a smaller straightening mend before the line comes tight, follow the swing with the rod, and let the supported materials swim rather than stripping immediately.
Change swing angle, depth, and speed before cycling through unrelated colors; stop over-mending once the fly is fishing because each correction can lift it from the lane.
04
Mistakes to avoid
Calling every articulated or large steelhead swing fly an Intruder.
Treating one color, material station, weight, shank, tube, or trailing-hook layout as universal.
Over-dressing until the fly holds water, fouls, casts poorly, or loses the supported sparse silhouette.
Inventing a hook arrangement for the photographed purple tube form when the independent hook and final rig are not visible.
Ignoring local rules for trailing hooks, shanks, tubes, added weight, barb, leader, season, or protected fish.
Make the choice
Choose the form before the color.
A family name is only a starting point. Use the waterline, construction, and observed food to narrow it to the form that fits the river.
Use Rows of Intruders as a breadth view only: it proves legitimate color and construction variation but does not identify one universal recipe, hook, station count, or weight.
Choose the Pink/red Intruder when a bright exact two-station shank-style profile fits the water; the photograph supports silhouette and color, not an unseen hook system or hidden ballast.
Choose the Purple Intruder Tube when tube construction is intentional. Pair the body with a separately sourced, lawful leader, junction, and hook system because those components are not shown here.
Choose depth before color: match eye or tube weight, sink tip, leader, cast angle, and mend to the lane while preserving a sparse supported profile.
Common variations
Small changes can make a different fly.
Three verified, non-AI CC BY 2.0 photographs show exact source-labeled Intruders: a multi-color family board, a pink-and-red two-station side profile, and a purple tube variation. The board is breadth evidence rather than one recipe; the tube photograph does not show or establish its separate hook rig.
Multi-color Intruder family overview
A source-labeled collection showing the range of sparse station-based forms without turning the board into one recipe.
Colors shown
purple, orange, chartreuse, black-blue, pink, red
Weighting
Varies across the collection and cannot be established for every fly from the overhead photograph.
Pink/red two-station Intruder
An exact bright side profile whose sparse center, supported front and rear stations, and visible eye are easy to inspect.
Colors shown
pink, red, pale flash, dark accents
Weighting
A front eye is visible, but its material, mass, and any hidden ballast are not established.
Purple Intruder Tube
An exact source-labeled tube variation with purple flowing materials and a chartreuse-black rear station.
Colors shown
purple, chartreuse, black
Weighting
The source identifies a tube form; tube material, internal weight, hook, and completed rig are not visible.
