Pat's Rubberlegs is also known as Jimmy Legs, Knotty Girls, Restless Stone, The Turd, and The Pickle. The pattern was constructed by fly fishing guide, Pat Bennett, who works out of the Hyde shop in Island Park, Idaho. According to Pat: "I began tying my first Pat’s Brown Rubber Legs in 1995 while at a cabin in Island Park that my grandfather built. Was there on leave while in the Army floating Box Canyon on one man pontoon boats with my son, Mike. We were using Montana nymphs and catching a few fish. I started looking under rocks and looking at the stone fly nymphs and thought they looked more brown than black. So I went to a fly shop and bought true brown chenille, some lead less fly tying weight, and some super floss that I thought was brown but it was true olive. True olive has a hint of brown in it and I didn’t like the rubber legs that were being used on the girdle bugs and so used the super floss. My son and I started catching a lot of fish on them. I started guiding in 1997 when I retired from the Army after 22 years of active service. By then had started tying the rubber legs in about 5 or 6 different colors and they proved very successful with clients. Solitude Fly Company picked it up in 2003 and has since been a staple fly amongst anglers."
The other fly distributors created similar patterns under different names. Jimmy Legs is a variation from Idylwild Flies in which the legs are pre-knotted and tied on a bent hook, such as a Daiichi 1730. Knotty Girls also have knotted legs but they are usually round rubber material. Restless Stone is another name as marketed by Umpqua. Whatever the name, the pattern works quite well and has become a favorite among guides. The pattern is a variation off an older pattern known as the Girdle Bug. This pattern was developed in the 1930's by Frank McGinnis of Anaconda, MT. He developed this pattern while fishing the Big Hole River. Originally, round rubberlegs was used but a spandex rubber material such as Super Floss, Flex Floss, Life Flex, and Spanflex has become preferred over round rubberlegs. It is much more durable and transparent than rubberleg material and very supple with lifelike movement in the water. Mickey Wooton, a guide out of West Yellowstone, came up with a nice variation of trimming the chenille at the abdomen for a flattened taper and replaced the antennae and tails with Krystalflash and Goose Biots, respectively. Fish Pat's Rubberlegs in the riffles and runs of fast moving water. It also makes a great pattern for short line nymphing. The weight of the pattern allows it to quickly sink into deeps slots and pools. Great with a Beadhead dropper such as a Prince Nymph or Hare's Ear.
