The Tungsten Split Case BWO from Solitude Fly imitates a Blue Winged Olive nymph with a tungsten bead for fishing deep in the water column. The split wing case adds realism during Baetis hatches, when trout feed heavily on drifting nymphs.
Dead-drift it in riffles and seams from spring through fall, matching the olive-bodied mayflies trout expect. Size #18 with tungsten weight reaches the feeding zone without added split shot.
