Little black stonefly nymphs are very effective on local rivers like the Madison and Gallatin year round, and particularly so from early fall through spring. Tying this fly on a jig hook ensures that the fly will ride with the hook point up, minimizing snags and maximizing your time spent fishing. The tungsten bead gets the fly down fast, and the addition of an orange "hot spot" behind the bead seems to really catch the attention of the trout. Whether you are here in the fall fishing for runners, on a spring road trip, or waiting for that next great summer hatch, make sure to give the Euro Stone a try.
