This is an Upside Down Dun. Not a style I use often, but when I do it rarely lets me down. The two main advantages with this style of fly, are... The hook point is, theoretically, hidden from the trout’s view and the body/ tails have a more natural curve than flies tied in the normal style. They have one reputed disadvantage … They are reputed to be poor hookers, I say reputed because I have never found this.
The fly I have tied is an Olive imitation, simply use the appropriate colours to imitate your selected Dun.
This fly is fairly easy to tie, but a little fiddly due to turning the hook a few times.


HOOK – Partridge Oliver Edwards Emerger, K14ST #14 – 20
THREAD – Olive UTC 70
BODY – Super Fine Dry Fly Dub (#14 Olive)
HACKLE – Blue Dun Cock
WING – Grey Polypropylene Yarn
TAIL – Microfibetts Tied Outrigger Style.

STEP 1
Mount the hook upside down in the vice and attach the thread at the point shown.



STEP 2
Mount the wing with figure of eight wraps, then lift and post the wings. I like to add a very small drop of superglue here to help hold the wings position.





Then cut to length.



STEP 3
Turn the hook to the “normal” tying position and dub on a small ball of dubbing at the point shown.



STEP 4
Mount two Microfibetts, one each side of the dubbing ball. Wrap the thread tight to the dubbing ball which will force the tails into the outrigger position.



STEP 5
Turn the hook again and dub the body.



STEP 6
Tie in the hackle.



STEP 7
Apply another pinch of dubbing and dub the thorax area.



STEP 8
Wrap the hackle over the dubbed thorax to the eye. Tie off and whip finish.



STEP 9
Turn the hook once more and trim the hackle fibres from the underside of the fly (top side of the hook)
For the finished fly.

Nice one Scotfly. Is there any reason that this could'nt be tied as a parachute? Just a thought, I think maybe I'll give it a try and if it comes out I'll post a pic.
Bill

I tied a few of these as parachutes and the look excellent. First time i tried them the fish seemed to love them and i thought they were the best thing since sliced bread! Untill I looked at my leader after a few casts! I coudnt twist it more if I tried. Shame, but not on my list anymore. Im not sure how this one stands upto spinning?

Hi, An early attempt at a parachute Upside Down Dun. It's very fiddly to tie and from what Rover says about twisting maybe not worth the effort!
I think I'll stick to your method Scotfly.
Bill

Would it not be hard to hook a fish when you are fishing with the hook upside down?

Willskip, there are parachute versions of it. Normally the parachute is tied on top of the hook (under the fly) using the LOOP method to tie in the parachute hackle. I don't tie them parachute style normally, I think this way is better,it's quicker,easier and more durable.
Rover, what material were you using to tie the wings when you had line twist problems? I don't have problems with this one.
Thanks Yaffle.
Cromie, I've already answered your question.

Thank you Scotfly. The link about the loop method is most helpful. I appreciate all the effort that you put into these step-by-steps and I have found them very useful.
Bill

Here's the two styles side by side Willskip.
Tried a different yarn for the wing on the Para version, not so keen on it though.

Hi Scotfly, thanks for posting a pic. of the two styles. The use of the mirror is a good idea and shows the two different styles to great effect.
On balance I think that your original version as shown in the step-by-step is the best way to go.
Thank you for your efforts,
Bill
