Tying the Uffe Killer by Ulf Hagstrom

Fly Patterns, Step-by-Step Tutorials — By on November 1, 2010 6:00 am

This is a fly that has been with me for several years. There are of a lot of ways to tie this style of fly, and the step-by-step below is the method I prefer. What makes this technique different from other similar methods is the way the hackle is wound underneath the body instead of above it and around the wings. I picked this up from the famous American fly tier, Poul Jorgensen, who I saw use this technique on an extended body deer hair pattern about six years ago.

I’ve had some great Vulgata fishing with this fly. The big advantage it offers is is extremely lightweight, and always lands the right way. About the name “Uffes Killer.” It was named by my good friend Björn Arkenfall. Being a big fan of “Tundrans öring,” he named the fly “Uffes killer” and it has been called that ever since.

Oh, what memories this pattern brings back– I can’t wait for next years Vulgata race to arrive!

Material List:

Hook: Any lightweight dry fly hook
Body: A “reversed” and varnished wood duck feather
Wing: Poly Yarn
Hackle: Brown

Preparation of the body:

Start with stripping away the lower fibers from a wood duck feather.

Cut off the tip, leaving about 1.5 to 2-centimeters (1/2 to 3/4-inches) of quill with fibers still attached.

Separate three fibers on each side, and stroke the other fibers downwards.

Add varnish to the fibers you stroked downward and stroke them repeatedly, adding more varnish if needed until you have a nice slick body where the fibers are stuck together close to the quill. I find using a more flexible varnish gives the best result.

Separate the top fibers on each side and do the same thing as you did with the body– add varnish and stroke them together. Do the same thing with two on each side, creating three tails.

The tying:

You can use almost any dry fly hook for this fly, I often tie it on a size #14 TMC 100, but you can also use a Partridge BNX15 like I am using here.

Cut off the front of the feather body so that it is the size you want (about 2.5-centimeters works for me) and tie it in somewhere around the middle of the hook with about four to five turns of thread.

Now slip your thread in between the hook shank and the feather and take five to six turns of thread around the tie-in point of the feather, raising it a little from the hook. Then slip your thread back up for one more turn on top of the feather.

Tie in the wing with a couple of figure-8 wraps on top of the tie-in point for the feather.

Take turns of thread around the base of the wings until the two wings almost meet. I have found that keeping the two wings at a slight angle from each other balances the fly, allowing it float much better.

Use a hackle with fibers a little longer than you would normally use for better flotation.

Wind the hackle first upwards and then downwards. Normally, you can fit in about five or six turns. I wind it quite carefully, trying to avoid fibers from becoming trapped so that they point downward.

Tie off the hackle at the hook eye and adjust any fibers from pointing downward (simply pluck them away) and cut the wing to shape.

    Hi, I personally like to use Dave’s Flexament for this. But you can use regular head cement for it aswell but you will get a stiffer body if using it.

    All the best

    Superb pattern, Ulf.

    I was browsing the web for hours trying to find inspiration for new ways to tie the Vulgata when I found this. Thanks!

    Any tips on which feather to use with the same pattern when tying Ephemera Danica?

    Thanks Daniel!
    You know this pattern was borned after fishing one of the lakes in Vättlefjäll in your region of Sweden! When I tie this for the Danica I use a mallard feather which is more white than the wood duck, it works for me! :)

    I thought this was such a beautiful fly, I had to try it out, but I wondered if it could stand up to several mean trout. I tested it at a catch-and-release club here in Ohio with wary pre-caught fish. The first turned around to come back and sip it in. After 4 13-16″ browns and rainbows (out of 10 trout that looked at it), the fly was as good as the first cast. It’s a great fly and fun to tie.
