This pattern is created by the great Norwegian fly fisherman Bjørnar Skjevdal.
He often use this pattern as a fish-finder. He look at the river, see the places where he believes the trout can be (he knows), then he fish this pattern right above the fish.
Hook : Ahrex FW520 Emerger #12
Tying Thread : Semperfli Nanosilk 18/0, White
Tail : Rabbit Zonker, Natural Brown (only the fùr)
Body : Ice Dubbing, Brown Olive (brushed hard backwards)
Head : Deer Hair, Orange
When you have attached the tail and dubbing. Use your dubbing brush and brush the fly hard backwards. Some of the dubbing fibers should be a part of the tail. Cut the deer hair as a muddler-head. But don`t make it to perfect, it has been proven that a "bad" tied head / cutted head fish better.....
