Kelly tied this pattern up before heading over to the Big Hole, and absolutely hammered the resident browns over there. The fly matches the rusty brown color of the Big Hole, but we have also done well with it on gin-clear waters such as the Madison and the South Fork of the Snake. The Big Hole Bug is similar to the circus peanut, but with a lot more marabou on the rear hook and pumpkin rubber legs. Size: 4 Articulated. Color: Brown/Yellow
