Funnel Dun

Funnel Dun

The Funnel Dun is a fly which Jack Blackman first introduced to us when we were still Natal Fly Dressers Society, Durban Branch – a long time ago.


Hook An up-eyed dry fly hook is preferred but a down-eyed dry fly hook works as well, sizes 12 to 18
Thread 6/0 – in colour to suit your chosen scheme
Thorax Any dubbing material, usually darker than the abdomen. Hares Ear blend works well.
Hackle Long barbuled cock hackle – colour to suit (I prefer a length of 1,5 times the hook shank)
Body Soft fur dubbing of colour to suit
Tail ┬áSame as for hackle – again 1,5 times the length of the shank.

Tying Instructions

1 : Place hook in vice, secure the thread and take it to a position just past the eye. Form a dubbing noodle with your selected material and form a neat thorax just behind the eye. The thorax should have a diameter of about a fifth to a quarter of the shank length.

2: Strip the flue off the hackle and tie the stem in at the back of the thorax, with shiny side out. Trim off the excess stem and wind the hackle backward (towards the hook bend) two to three times around the shank and tie off. Shape the hackles so that they form a funnel shape over the thorax. This is done by holding the hackle tips in the fingers of the one hand and winding the thread loosely up the barbules with the other hand and then back again. This should keep the hackle in the funnel shape. If the thread is wrapped too tightly the barbules will splay in all directions.

3: Wind the thread to a position above the barb and tie in three or four barbules for the tail. By holding the barbules down with your left hand, wind the thread to about a quarter of the way around the bend. Take the thread back to behind the hackle.Step 4: Dub body material onto the thread and form a tapered body by winding back to the tail. Tie off at the tail with a whip finish. The tie off can also be done with a yellow colour thread to imitate an egg laying insect.

Happy hunting!
