How to Tie a Son of San Juan Worm

The Son of San Juan Worm is the subject of this week’s featured fly tying video.  Tim Flagler says of this odd but effective pattern: “I know the ends look too long with respect to the body and the hook size but I think motion is absolutely key to the success of this little pattern. Here the rubber legs have been cut to a more reasonable-looking length but as you can see, the front and rear segments don’t have much motion. The same is true when they’re underwater. With longer front and back segments, you get a lot more motion, particularly underwater.”
