|The materials you will need for the Utah Killer Bug|
To tie my version of the UKB you need only two materials; 0.20mm pink wire and oyster coloured Jamieson's of Shetland Spindrift wool. I have found the best size for this fly is 12, although I do tie them in 14's.
Use a drop of superglue to sucure the wire underbody and start wrapping the wire at around the two-thirds point back from the eye.
Wind the wire in touching turns to the eye. Take one long wrap back so the wire is at the one-third point on the hook shank and reccomence the touching turns back around the bend. Once you have wrapped a second layer of wire covering the middle section of the shank, make another long wrap to the starting point of the wire and trap down the tag end. Helicopter the tag end off and make another couple of turns of wire and leave; the wire will not unravel. The underbody should appear to taper up from the eye to a thicker middle and taper back down at the end of the body.
Tie in a length of wool starting where the second layer of wire ends - keep hold of the tag end - wrap the wool to the eye, then wind the wool back towards the bend so there are two layers of wool. When you reach the tag end of wool trap it with one or two wraps of wool and cut off the excess. Continue to where the wire has been left and tie off the wool with four or five turns of wire working back towards the eye. Trim the remaining wool and cut the wire close; a drop of superglue on the wire will keep it from coming undone.
The fly transforms into a fantastic subtle pink colour, that appears translucent when wet.
