The Intruder Fly Pattern - no that isn't correct. The Intruder Fly originally tied by Jerry French, and Ed Ward, was a concept pattern. The concept was to tie a large fly pattern with a small trailing hook. Before the Intruder, large flies were tied on large hooks. These hooks damaged the Steelhead for release - they were tied on large ott (1/0, 2/0 3/0…) hooks that were cutter hooks that kept slicing into the fish's mouth.

Second part of the concept was to tie a fly with two stations - a rear and forward station. This allowed a large fly to cast easier.

Since the 1990's this fly has continued to morph. The reason for this is in the word Intruder which refers to two things:

1. The fly concept that Jerry French and Ed Ward developed.

2. An Intruder is something that anadromous fish respond to - other small fish in their redds hanging around to eat their eggs.

Large flies tied in an Intruder Style can also represent food like squid and shrimp that steelhead and Salmon have foraged on in the ocean.

Intruder Flies for Steelhead, Salmon, and Sea Run Browns

What does an Intruder suggest or represent to a Steelhead?

Possible Responses:

  • Automatic Condition Feeding Response - representation of a squid, prawn or fish.
  • Curiosity Response – Large 3 to 6 inch Intruders are large animated attractors that instigate Steelhead, Salmon. And sea run Browns into striking.
  • Survival Competition Response – An Intruder may eat eggs, and the survival response is to remove they prey.
  • Territorial Competition Response – when Steelhead come into a holding area they often setup a territory. When an Intruder swings through their area and bite response is initiated.
  • Anger Response – an Intruder has disturbed the peace, a Steelhead’s space.

What to Look for in an Intruder:

1. Size (bigger is often better) This depends on water clarity and water temperature. Clear water = smaller; Cold water = larger.
2. Shape, profile and outline (what does the fly look like when it is wet and swinging through the current.
3. Color - Steelhead are color-conscious to the extreme.
4. Movement – does the fly have movement in the water, not the air.
5. Casting ability – can you cast the big Intruder. Big flies = big rods, and heavier sink tips. Or adjust your cast. You can Perry Poke Spey Cast a big Intruder if you are having trouble.
6. Durability – will they fly stand up to casting a fishing punishment.

Moal Leech - Product Image

Moal Leech

Moal leeches are tied entirely on a string with a trailer hook at the back. This gives the fly greater action than a fly tied on a rigid hook. More fish are landed with the Moal fly as well.

The tried and True Mother of all Leeches. The classic Strung Out MOAL (Mother of all Leeches) is the one thst started it all. Invented by Derek Fergus is is one heck of a pattern. These really are a pattern you need if you hunt Steelhead. Because we use a Octopus hook the short shank holds fish far better allowing more fish to hand. Because it is tied on a string (gel spun) the fly tends to wiggle and swim in the current. Specially swinging them.

Size 2 trailing hook - 3" long  (custom flies tied with bead heads)

The Moal Leech catches Steelhead in all conditions. Add it to your fly box. You will never look back.

"I wanted to thank you for your fast service and a great product.  I have
been fly fishing for over forty years and have caught hundreds of trout and
salmon and even a few bonefish but I had never caught a steelhead on a fly
before last weekend.  With my fifth cast of your black and purple MOAL into
a nice Clackamas riffle I hooked and landed a small hatchery summer hen.  I
attached a picture although it doesn't show the fly too well (my hands were
still shaking)." -

    "This is the only fly box I use now. In the summer I will put several skating or muddler type flies into one tube. For big steelhead flies it a must have item. I have tried so many different fly boxes, but it was always the bulk that gets in the way of Spey casting, or closing the lid down and munching the flash of marabou that gave birth to this simple fly storage solution." - Jeff Layton

    Sugar Bunny

    My brother and I recently went to the Skeena river for the first time for Summer run fish. We had some pretty good Intel on a few runs and techniques. One thing that my source stressed was that if we waded out past our ankles that we were fishing too far out! Man was he right! It took me a few days to catch up to my brother who was fishing left handed and close because of tennis elbow in his right arm. He was really getting into the fish, hitting 4 steelhead the first day on a (Fish Magnet Summer Methow)! The biggest problem was all of the plucks, and short strikes from traveling fish. I was a zero with lots of on offs until the third day when I put on a sink 3 on my Rage head and started swinging it into the beach. Then my trip really began as I managed some nice fish mimicking my brother with a Fish Magnet Summer series Methow fly* that proved very good for Steelhead and Coho.

    Flash forward a couple of weeks and the same trip with Jeff at Grabflies. Fishing has been tough all over and the Skeena was no exception this year with a near record low steelhead run. We were going to have to work hard and step up to be successful. This time it was me that hit the ground running having learned my lesson! Prior to the trip I worked on a fly that would be smaller, darker, casts easily on a light polyleader and moves with very little current while showing off a red bead by the hook that would hopefully give the fish a point of attack so the hookup rate would go up with the fast traveling Skeena fish.

    It is basically an April Vokey Sugar Pop fly without the Rhea and an added black rabbit zonker tail with the flash right on top of the wing. Introducing the (Sugar Bunny) Man this fly really fit the bill. I could have called it the Labrador retriever because the tail looks like a dogs tail wagging the flash back and forth. Winner Winner Steelhead dinner!

    I had many grabs and fish on and lost along with a couple of dandy mid to upper teen steelhead caught the first two days. We think the Coho were the plucking fish, but we also lost some big steelhead deep into the battle.

    Jeff soon learned his lesson as I did, as he said "keeping one foot on the bank" and hit three steelhead on his third day, fishing a light tip and a light nice moving fly called the (Egg Dropping Methow Rhea Taco) one of the fish took him down the river and got off at the bank that we dubbed the Kispiox buck because of his 20# + size and nasty demeanor.

    Jeff also caught a some on a lightly weighted (Skagit Methow Leech) which is always a good fly to tie on.

    Later in the week the river cleared up some and the fish moved out from the bank and I fished another new fly that was incredibly successful, hooking three steelhead in one run on the final morning. Jeff and I managed a double as well, each catching a nice mid teen chromer!  I'm dubbing my new fly (the  Hoh Magnet) It is a highly visible mostly black fly with a dark blue flash wing and Lady Amhurst barbs that says "bite me" I will be adding it to the Fish Magnet fly collection as soon as I can tie some up and get them to Jeff to be available.

    Greg's Kriller, Red

    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!

    HoBo Spey - custom tied by Grabflies using quality (best) materials:

    A great time tested and proven Steelhead pattern. Black and blue is money for Steelhead. HoBo has lots of movement in soft water because of the Marabou. Grabflies ties this pattern with a dubbing ball before Intruder Prop hackle and then black Marabou. This stops the Marabou from collapsing flat, but instead gives the fly shape and movement.

    Hartwick's Hoser Tube presents a giant, flowing profile in the water. Weight has been added in the form of a tungsten cone. Not only does this cone add weight, but it is tied in reverse so it creates a solid bump where the marabou is tied in. The marabou will not collapse and the profle remains, even in the fastest water.
