Ralph Cutter's "Bugs of the Underworld" DVD has footage of a dislodged stonefly drifting along the river bottom. The nymph appears light as a feather, arching with legs outstretched as it's lighter colored abdomen rolls into view. Cutter contrasts the appearance of the natural nymph compared to the usual rigid, heavily weighted stonefly pattern. With this in mind, I tied up a few unweighted articulated stonefly prototypes and thought I'd give them a try on my recent trip to MT. Taking a brief break from streamers, I dead drifted one on the Yellowstone last week and produced this whitefish on the first cast. I'm guessing if I had the patience to keep nymphing, I could have eventually hooked a trout. Just food for thought (no pun intended) for future stonefly designs.
