This particular pattern is deadly when mayflies are in the water and about to hatch. I usually tie this pattern up in sizes to to match BWOs #16 or 18.
Hends body quill comes in all different colors and you can tie this pattern to match any mayfly nymph.
I also tie this pattern in a brown and even black.
A note about Coq De leon for the tail…yes it is expensive but a little goes a long way. Also stiff fibre tails actually help your nymphs appear more natural in the water as the fibres act as a rudder.
