The Idea Behind Danica Dun

Information About Danica Dun

This fly is more or less based on one of my earlier ideas, which I originally named “A little foam trick” The concept is straightforward: use a small foam tube as a wing post by attaching it to the hook shank approximately 2 mm from the hook eye. The buoyancy of this type of horizontal wing post is incredibly good, so perhaps I should have named the fly “French Partridge with a Life Jacket.” However, for now, it’s “just” a Danica Dun.

The foam also has an excellent ability to hold the hackle and wings in the desired upright position. All the materials used are very soft, which is particularly important for the tails, as overly stiff tails can negatively affect the hooking of fish. The body, or abdomen, in this demo model consists partly of floating kapok dubbing and partly of a water-absorbing type of yarn. The idea is for the abdomen to penetrate the water surface and sit rather deep below during fishing. The buoyancy provided by the foam, cdc, and deer hair in the thorax is so impressive that the abdomen can essentially be made from almost anything. Hare dubbing, which absorbs water, could also be a good choice.

Step by Step tying guide

How to tie Danica Dun

Before We Can Start, Ensure You Have the Following Materials:

  • Hook: Maruto d21 size 10

  • Thread: Classic Waxed 12/0 from Semperfli, primrose for the abdomen and brown for the thorax.

  • Tails: 3 strands of ostrich herl from small body feathers

  • Rib: Dirty Bug Yarn, Caddis Brown from Semperfli

  • Abdomen: Kapok dubbing, Danica color from Semperfli

  • Thorax: Deer hair, Golden Brown and olive CDC dubbing

  • Wingpost: Foam tube, 3 mm in diameter, gray

  • Hackle and Wings: 3 pcs. of cdc feathers, gray, and one French Partridge feather.

Danica Dun Tying Guide - Step 1

Attach the Hook and Tails

Place the hook in your vise and then wrap the thread onto the hook shank. Tie down three pieces of ostrich herl as tails near the bend of the hook. I attach all three tails to the hook shank at the same time and then separate them afterwards using my thumbnail, which I place on the bend of the hook and press beneath the tail rod. The tails can now be secured in the desired position with a small drop of UV glue or a few wraps of thread between the individual ostrich herl.

Danica Dun Tying Guide - Step 2

Attach the Rib Material

Wrap the rib material onto the underside of the hook shank. Leave approximately 1 mm of space from the tying in point of the tails to were you tie down the rib material.

- Michael Olesen

Danica Dun Tying Guide - Step 3

Attach the Dubbing

Apply the dubbing to the rear two-thirds of the hook shank. Start with a small amount of dubbing between the tails and the rib materials tying in point.

- Michael Olesen

Danica Dun Tying Guide - Step 4

Wrap the Rib Material

Now, wrap the rib material in open wraps around the body approximately 4–5 times. I prefer to wrap in the opposite direction of the thread’s natural flow, which prevents the ribs from becoming completely submerged in the dubbing and also makes the fly slightly sturdier.

- Michael Olesen

Danica Dun Tying Guide - Step 5

Prepare the Deer Hair

Cut a small bundle of deer hair from a skin. The bundle should be about half the thickness of a pencil. Hold the bundle at the thick end with your thumb and forefinger and gently roll it flatter between your fingers. Then, grap the deer hairs with a paper clamp or a similar tool. Once the hairs are evenly distributed in the clamp, trim the ends with a long pair of scissors.

- Michael Olesen

Danica Dun Tying Guide - Step 6

Change the Thread Color

Switch the thread to a brown color, or color the thread with a marker. Create a loop of thread at the end of the dubbing body. Place the hairs in the loop and twist them with your dubbing twister.

Danica Dun Tying Guide - Step 7

Twist the Deer Hairs

Wrap the deer hairs tightly over the rear half of the thorax area.

- Michael Olesen

Danica Dun Tying Guide - Step 8

Finish the Deer Hairs

Now, cut the deer hairs on the top and underside, and remove individual hairs from the sides.

- Michael Olesen

Danica Dun Tying Guide - Step 9

Twist the CDC Dubbing

Wrap a little cdc dubbing on the front half of the thorax.

- Michael Olesen

Danica Dun Tying Guide - Step 10

Attach the Foam Tube

Tie a 3 mm foam tube (soft foam) down on the thorax using 3 wraps of thread.

- Michael Olesen

Danica Dun Tying Guide - Step 11

Create a Loop of Thread

Next, create a loop of thread at the same point or on the hook shank, between the foam and the hook eye.

- Michael Olesen

Danica Dun Tying Guide - Step 12

Prepare the CDC Feathers

Place three large cdc feathers on top of each other. Hold the feathers with a clamp and trim the feather stems away using long scissors.

- Michael Olesen

Danica Dun Tying Guide - Step 13

Twist the CDC Feathers

Wrap the cdc feather strands into the loop of thread and wrap them 5–6 times over the tying down point of the foam. 

- Michael Olesen

Danica Dun Tying Guide - Step 14

Prepare the French Partridge Feather

Prepare a French Partridge feather as shown in the picture, with the barbs stripped off on one side.

- Michael Olesen

Danica Dun Tying Guide - Step 15

Attach the French Partridge Feather

Tie the French Partridge feather in at the tip end, on the underside of the thorax, as shown in the picture.

- Michael Olesen

Danica Dun Tying Guide - Step 16

Twist the French Partridge Feather

Wrap the French Partridge feather over the foam, in front of the CDC strands. Secure the feather stem behind the hook eye, where the fly is also finished.

- Michael Olesen

Danica Dun Tying Guide - Step 17

Trim the Foam Tube and Fly

Cut the foam tube to the desired length and trim the fly slightly on the underside.
