This is a heavy fly. Well weighted with lead. Fish this one with an indicator, and work your way down the river.
You can easily change the color of the body, it all depends the color on the tying thread.
Hook : Ahrex FW540 Curved Nymph #10-14
Tying Thread : Semperfli Classic Waxed thread 6/0, Red
Weight : Lead, shape the body with it.
Body : Latex (over the tying thread)
Spot : Fluoro Dubbing, Yellow
Thorax / Head : Hares Blend Dubbing, Black
Shape the body with the lead. Use superglue under the lead so it sticks to the hook. Then shape the latex strips so it lays in nays wraps around the fly. When you have tied in the two dubbing parts, brush the fly hard
