Originator: Kenneth Bostrom in 1967


Hook:  Light dry hook #10-#18

Thread:  To match color of yarn.

Material:  Polypropylene yarn


Note 1:  May be tied in size and color to imitate your local caddis flies.


Note 2:  Other names used for this fly: Polysedge, Rackelhahn


Note 3: Pictured fly is tied with brown dyed Polywing material.






The construction and the idea of Rackelhanen was developed in 1967 during a hatching of caddis in Vannan River located on the border between the counties of Kronoberg and Halland in Sweden.  


The fish was extremely selective on a special caddis, whose pupa hatched just below the surface.  The fish only took the hatched fly in the zone between, 10-20 cm below the surface and up to the surface.  The pupa, would be an easy target all the way from the bottom to 10-20 cm from the surface.  But this pupa didn't interest the fish, neither did the hatched fly that rested on the water surface ready to fly away.  This hatching kept going on for several evenings.  


I finally understood the problem, I found the right method to copy this hatching procedure after a long time of experiments.  It took some time, but when I had found the right material (polypropylenyarn), the tying technique and the fishing technique - the Rackelhane fly turned out to be deadly efficient.  


The fly was not very beautiful, it's appearance was almost frightful.  Because of this I was very reluctant to show the fly to my fishing friends. I was always prepared for laughs, but soon the laugh changed into other expressions, when they took the time to try my creation.  It was one of my fly fishing friends who named the fly Rackelhanen.  He thought the fly looked like a "bastard."


The name Rackelhane comes from the Swedish name of a cross between a Black Grouse male (Heathcock - Lyrurus t. tetrix), and a Western capercaillie, ( Tetrao urogallus, female).  They are two gallinaceous European gamebirds.



Fishing Technique 


During the years I have developed many different fishing methods with Rackelhanen.  I will try to describe the most important methods. Rackelhanen almost always is fished in the surface and with a floating line.  But at certain times it could be better to choose a sinktip line.  A Rackelhane should always be treated with a floating substance.  Many people have misunderstood the quality of polypropylene, and believe that it floats well without treatment, but it won't!


Caddis have many different ways of hatching.  These ways must we, as anglers know how to imitate.  The Rackelhane makes a blurry silhouette when it is looked at from underneath against the sky.  This is most likely the best explanation why the Rackelhane is so efficient.  The material gives the impression of life, and the caddis are never still either on or in the water, in contrast to the mayfly.

Technique 1.
Stripping on the surface. Short and "nervous" pulls, 2 inch long, with a short pause between them.  This imitates the behavior of egg laying or drinking caddis

Technique 2.
When I see the fish eating "swimming" "paddling" caddis pupae on the water, I usually cut of the wings on Rackehanen and present it as a surface swimming pupa heading for land.

Technique 3.
A - Let the leader sink.  You can gladly use a sink tip line with a short tip.  B - Pull the line so that the fly drags under the water surface.  C - Make a short pause, and the fly floats up again with a plopping sound.  This technique gives a perfect imitation of a caddis that is hatching just below the surface

Technique 4.
You can also fish Rackelhanen completely free floating as a dry fly, imitating a spent caddis.

During the years I have tested the Rackelhanen on many different species of fish, e.g. trout, char, rainbow trout, cutthroat, grayling and many more, both here in Europe and in USA.  Everywhere the fish have taken my fly with the same confidence and trust as Swedish trout.  Because of this I strongly believe that you can find it worth your while to try Rackelhanen on your next fishing trip.




Use a prewaxed thread of the same color as the rest of the fly.  Cover the shank with thread down to the bend, turn here and wind a couple of mm in the opposite direction.  Wax the thread thoroughly, dub it with 1 cm long cut pieces of poly yarn that you have fluffed up.




Wind the two first turns down against the bend.  Here you turn and wind in the opposite direction.  This way you can trap the fibers from the first turns (otherwise it's difficult to have these stay in the right position) down under the body material.  Remember to leave space for the wings and front




Cut a piece of the poly yarn and use the right amount of fibers for the hook size you are using.  Tie the yarn on to the hook as shown in the picture.





Fold the other wing-half backwards and fasten it with a couple of thread turns over the wing-base.  Remember to leave enough space for head and front body.





Trim the wings by cutting them just behind the hook bend.  Important that you don't make them too long.





Dub the thread again with 10-20 mm long bits of fluffed poly yarn and tie the front body.  Finish the fly by making a small head with tying thread.  You can varnish the head if you feel like it but it isn't necessary, because we used the pre-waxed thread.

Streaking Caddis

Originators: Kenneth Boström and Lennart Bergqvist


Hook:  Mustad 94840, size 8.

Thread: Monocord B, or any other strong thread.

Body Rear: Fly-Rite #20, dark tan.

Body Front: Deer hair.

Wing: Deer hair.


Note 1 Trim hair in a triangle shape as seen in below photograph.   Scroll down for Instructions.


Note 2:  This Dry fly imitates the Phryganea Grandis, the largest caddis fly in Scandinavia.  You can also use this pattern to imitate smaller caddis by reducing the hook size.  You can also use colored deer hair to imitate your local caddis better, or mix grey and brown deer hair.  


Note 3:  Impregnate the fly before use.






1. Dub Body...







  2. Measure deer hair and grip hair at tie in point.






3. Without moving hair from hook position, switch hands, and tie in with 2 wraps.





 4. Tighten thread to flare deer hair as shown.







5. Trim hair into shape.  When viewing the finished fly from the front, the front body should be triangle-shaped, with a flat cut bottom (see top picture).



Finished fly should look like this.
