Stu's Chinook Intruder Fly

Stu's Chinook Intruder Fly is a bold, flashy streamer-style pattern that suggests a wounded baitfish and a mouthful of bright trigger colors, and it has earned a reputation as a go-to choice for Chinook salmon when you want a fly that stands out fast. This is a must-have in the box because its intruder profile pushes presence without needing a huge hook, giving you a big look that salmon can find and commit to. It is built for salmon anglers who want a proven, confidence pattern for Chinook.

What It Imitates

This pattern does not copy one exact insect, it leans into a baitfish and egg-sucking leech style impression with a large, pulsing silhouette. The long fibers and bright contrast create the look of movement and vulnerability, which can trigger aggressive takes from salmon in moving water.

Why We Like It

We like Stu's Chinook Intruder Fly because it delivers the classic intruder look with attention to clean proportions and strong color options, so you can match water conditions and fish mood without changing your whole approach. It is tied by Aquaflies, giving you consistent build quality when you are cycling through flies during a tide change or a prime travel window. The 40mm size hits the sweet spot for a big profile that still fishes cleanly on modern salmon swing setups.

Comparisons

Stu's Chinook Intruder Fly vs a rabbit-strip leech:

A rabbit-strip leech is all about a heavy, fluid strip that swims with a steady, natural pulse, which is great when you want a darker, simpler profile. Stu's Chinook Intruder Fly leans brighter and more suggestive, giving you stronger contrast and a bigger intruder outline that can be easier for salmon to pick out in tinted water or broken light. Choose the rabbit leech when you want a more natural look and slower, smoother movement, and choose the intruder when you want a louder silhouette and sharper color trigger.

Stu's Chinook Intruder Fly vs a traditional marabou spey fly:

A marabou spey fly fishes with a long, flowing profile that can look very alive on a slow swing, especially in softer seams. Stu's Chinook Intruder Fly keeps that movement idea but adds a more compact, layered intruder shape that holds its profile across varied currents and speed changes. Pick a spey-style marabou pattern when you want a slimmer, more classic presentation, and pick this intruder when you want a fuller target and more built-in contrast.

Stu's Chinook Intruder Fly vs a tube intruder in a similar color:

Tube intruders offer flexibility because you can change hook size and style without changing the fly body, which is useful when you are dialing in hookups or matching local rules. Stu's Chinook Intruder Fly gives you the intruder concept in a ready-to-fish format that is simple to rig and quick to cycle through when the bite window is short. Choose a tube intruder when you want maximum rigging options, and choose this fly when you want a dependable intruder profile with fast, straightforward setup.
