The Beadhead Flashback Stone Black is a robust and highly effective nymph pattern, designed to mimic the stonefly nymph with added flash and visibility. The beadhead assists in getting the fly down into the feeding zones quickly, while the flashback feature reflects light, mimicking the natural glistening found in many aquatic insects. This fly is particularly effective in fast-moving water and during stonefly hatches. Anglers should use a dead drift approach, possibly with occasional twitches, to effectively simulate the natural movement of stonefly nymphs along riverbeds.
