The Pat’s Rubber Legs was created by guide Pat Bennett*—of Hyde Outfitters in Island Park, Idaho—building on other big stonefly patterns, such as the Girdle Bug. This particular color pattern–black and coffee–is a particular favorite of guides throughout the Rockies, and they’ll fish it year-round as a searching pattern.
The only problem with Pat’s pattern is that it looks simple but can be rather frustrating to tie because the rubber legs can be hard to handle. But in this great video by Tim Flagler of Tightline Productions, you’ll learn a couple modern tricks for attaching the legs that make everything easier. If you haven’t yet invested in some UV-cure resin, this video might convince you that you really need it.
And if you’ve got the bandwidth, make sure watch Tim’s videos in full 4K resolution. You’ve never seen fly tying look so good.
