The KGB Leech!

... a tripple f on steroids!

The KGB Leech

OK up next is the “KGB” Leech fly fishing pattern … and this one is quickly becoming one of our favourite leech patterns for both early spring and late fall fly fishing in the BC Interior!

Philip Rowley's "Glenn's Leech"

For the last few years we’ve been trying to figure out how to improve on the Triple F leech.  Now don’t get us wrong … the Triple F Leech is an awesome BC Interior fly fishing pattern, and it’s certainly caught a lot of fish to prove it, but it does have one small weakness in that its marabou tail is quite fragile.  So … one evening while flipping through Philip Rowley’s book, Fly Patterns for Stillwater: A Study of Trout Etomology and Tying, we came across  “Glenn’s Leech” – you know, the one with the strong rabbit strip tail! :shock:

At that point we considered simply going with Glenn’s leech but the problem we saw was that although it solved the fragile tail issue, it simply transferred the weakness to its marabou body. So instead, we combined what we felt were the best qualities of each fly and voila … Krazy’s version of Glenn’s leech (Beadhead included) was born – AKA the KGB leech! And the conclusion, after a years worth of test driving it through every type of stillwater scenario that we could think of, is that it’s the real deal baby! This is a must have BC interior fly pattern that has earned a permanent home in our fly boxes!

Well I’m sure you clicked on this post to learn how to tie a productive BC interior fly fishing leech pattern and not to hear us ramble on about its origin so, with out further a do, here’s the recipe: (and although we tied this one in black/red, the variations are endless – black/blue, olive/red & brown/gold have also proved to be serious trout killer patterns)!  ;)

....... the bruiser!

The KGB Leech in Black & Blue ... "the bruiser"


  • Hook: Mustad Signature C49S OR Togen Scud – #8
  • Bead: Red Glass
  • Tail: Rabbit Strip
  • Tail Flash: Red Krystal Flash
  • Body: Wire Dubbing Brush (fine silver wire / black with red dubbing)

Tying Instructions:

  1. Place bead on hook, start tying thread behind bead & wrap thread down to hook bend.
  2. Tie in rabbit strip for tail.
  3. Add 2 strands of Krystal flash to tail – wind thread to head.
  4. Tie in wire dubbing brush & tie it down to the hook bend – return thread to head.
  5. Wind wire dubbing brush up & tie off behind bead at head.
  6. Whip finish – krazy glue ….. and you’re done!

And the video:

And if the wire dubbing brush is not your thing (yet) don’t despair … for a slightly different but equally effective variation simply substitute the wire dubbing brush with plastic chenille.

... the plastic chenille version of the KGB!

The KGB Plastic Chenille Leech!

Inspired by Brian Chan’s Plastic Chenille leech, this variation of the KGB is still very strong while providing a great deal of glitter … extremely effective in the early spring and late fall when attractor patterns seem to be the ticket! ;)

Well that’s it folks ……… spring is here so tie some up and give it a go!

*PS – If you’re interested in learning more about effective stillwater fly patterns you really should check out the following books!  Between Jack Shaw, Brian Chan & Philp Rowley, there’s not a lot of fly patterns left neccassary to be successful on any body of water in our province & beyond!
