The Plecoptera order of insects is one that should never be overlooked when fishing for insect-feeders like trout, grayling, arctic char and whitefish. Tie this nymph on while matching the hatch or as a wildcard on a secondary leader rig for imitating an overall attractive rising nymph. Tied on an Ahrex FW561.
