The Intruder is a modern classic for swinging flies to aggressive anadromous fish. Designed to push water and show a bold, pulsing profile, this pattern comes alive on the swing-breathing, flaring, and collapsing with every change in current speed. The articulated construction delivers maximum movement with minimal bulk, making it effective across a wide range of water types and conditions. Fished on sink tips or intermediate lines, the Intruder excels when you need to get noticed-whether covering broad tailouts for steelhead or probing heavier runs for salmon. Its combination of motion, silhouette, and presence makes it a go-to choice when fish are willing to chase and commit. A confidence pattern for anglers who believe in covering water and letting the swing do the work.
