Bi-plane

Originally developed by the tiers from Blue Ribbon Flies in West Yellowstone MT to imitate a still born baetis dun, this pattern can be adapted to any hatch by changing size, body color and wing color to match the natural.  The Bi-plane as with other “cripple” patterns is most effective during heavy hatches when the trout become selective toward defective emergers.

This simple, quickly tied fly consists of a sparse trailing shuck, a sparse spent wing and a dubbed body.  When tying, figure eight the dubbing thru the wing tie down spot to form a thorax.

Hook : Dry fly; #16 – #24

Shuck : Light brown zelon

Abdomen : Olive dubbing

Thorax : Olive dubbing

Wing : Dun zelon
