The Intruder

The Intruder has quickly become one of the most popular steelhead patterns on the West Coast. It is a large profile fly that was designed by West Coast steelhead guides Jerry French and Ed Ward, with the help and feedback of fellow anglers Scott Howell and Dec Hogan. They were searching for a style of fly that had a large profile but was easy to cast. Conventional hooks did not provide an adequate tying platform for creating large, plug-like silhouettes, so they turned to shanks and trailing hooks. Since its inception, there have been numerous variations of the Intruder, and it is safe to say that it is more of a style of fly rather than a pattern.


Whether fishing for salmon, steelhead, trout or Sea-Run Browns, the Intruder is a productive fly. Tied correctly, it will hold its profile in moving water. It is important that the Intruder have stable shoulders so the ostrich or other flowing material will not collapse as it is swimming. At Aqua Flies, we use the methods Jerry French created to tie an Intruder so it swims properly and is durable.


We are proud to offer the largest commercially tied selection of Intruders. Aqua Flies has devoted much time and capital to create a platform for other tiers to tie their own Intruders. By purchasing the AquaTalon hooks, the Aqua Fly Shanks, Aqua Fly Intruder Eyes, and the Un-Real Jungle Cock, a fly tier can be creative and expand upon the style of fly known as The Intruder.

Ultra Mini-Intruder


Jerry French's newest Intruder design utilizing the Ultra Rig. The Ultra Rig is a new system to rig shank flies with a trailing hook. The Ultra Rig is made with 50 pound Spider Wire, Ultra Tubing and a size 2 AquaTalon hook. This rigging system eliminates the use of wire as a trailing loop. The Ultra Rig system allows the angler to change out the hook without damaging the fly or the trailing loop. The only commercially tied fly with this rigging system.  In addition to the rigging system, this intruder is tied using an Aqua Flies Shank, Aqua Flies Intruder Eyes and the Aqua Flies Un-Real Jungle Cock.

Jerry's Intruder

The birth of the Intruder was in the Pacific Northwest. It has gone through many evolutions and surely it will continue to evolve, but Jerry's Intruder as it is tied today is a fish catcher. Tied using composite loops, UV materials and an AquaTalon size 2 hook, confidence is high when using this fly. Jerry's Intruder is approximately 3" long. Single Station Intruder is about 2" in length.

Kevin Feenstra


In his early 20’s, Kevin began guiding in West Michigan as an alternative to graduate school. Now more than 20 years later, he has never looked back. Kevin’s passion is swinging flies for migratory fish, but he loves to fly fish for any predator that swims. He now resides in Newaygo, Michigan, guiding around 200 days/year on the Muskegon River system (and fishing whenever he can). His steelhead, smallmouth, and trout flies have been published in books, magazines, and online. He has written articles for international, national, and regional fly fishing magazines.


Grapefruit Leech: With its chartreuse and pink head, the grapefruit leech is one of the most reliable Midwest swung fly patterns. It always can work but is exceptional in cold winter temperatures.


Halloween Leech: This is a black and copper swung fly for steelhead. Over the course of many years, this is a go to fly that works year after year. Often times, when fishing two clients, it is fished interchangeably with the grapefruit leech. It is a safe bet that one of these two patterns will take fish. The Halloween Leech is at its best in October-December and again in the spring.


Aquatic Nuisance: This copper and green sculpin pattern takes large steelhead and lake run browns through the fall months. It works well any time you need to push water and is often used during low light times of the day.


Emulator: One of my oldest patterns. This fly is more or less timeless and is a reliable pattern for steelhead when nothing else is working. It is also proven effective for trout and smallmouth bass.


Australian Possum Hex: Versatile pattern that can be used any time steelhead are present. It also makes a great generic fry pattern.


Better than Spawn (BTS): The BTS is a staple salmon fry pattern. Steelhead and trout devour this pattern in the spring. Even though it is a fry pattern, it works well any time steelhead are present.


Cow Killer: This is a dark version of the Aquatic Nuisance. It is deadly in the fall months when fish numbers are good. With its dark color and big profile, it is a perfect choice for fishing early in the morning or late in the day.

Greg's Kriller

Constructed on the banks of the Kanektok River the killer krill, or Kriller, was designed for maximum castabilty as well as its flaring motion when swinging across hydraulic “fences” in the water column. With the weight of the dumbbell eyes at the back of the shank, the Kriller swings deep with more of a downward-diagonal profile than most traditional patterns. A devouring size for both chrome Chinook and Steelhead, having the eyes closer to the hook attracts some of the most aggressive eats you can find near tidewater!

Luke's Chromewrecker

The Chromewrecker was originally developed by Lucas Meeker as a large-profile, un-weighted pattern for targeting big water Steelhead in the lower flows of late summer and fall. Fishing big flies un-weighted with a heavier sink tip allows the fly to keep the large profile of a big weighted winter fly, but stay up in the column to snag less in broader and more consistent gradient runs. Many big steelhead flies sink slowly, especially un-weighted, but the Chromewrecker is tied with sparse materials that don't slow the sinkrate.


As the pattern evolved over three years, Luke added weighted variants and colorways targeting winter Steelhead and Chinook. Another central idea in this pattern is to use multiple shades of colors and contrasting points to build blended colors and markings that more closely resemble how colors blend and fade in nature (even when the color is bright!)... like the blended markings on the flank of a bright chrome Steelhead.


Colors available: Blue/Purple/Chartreuse, Pink/Purple, Black/Chartreuse/Olive, Avalanche (pink/white), Fall Favorite (red/orange).
