This is the Diawl Flashbach, a long shank variation of the Diawl Bach and one which for me has been more successful than the standard dressing.
Instructions assume right-handed tyers
HOOK ? Kamasan B200 #12
THREAD ? Brown 8/0 Bennechi
TAIL ? Brown hen hackle fibres
BODY ? Peacock Herl
RIB ? Copper wire
BEARD ? Brown hen hackle fibres
THORAX ? Peacock Herl
CHEEKS ? Medium flat pearl tinsel.
STEP 1 Mount the hook in the vice, attach the thread and wrap towards the bend. Catch in the rib under the shank as you go.

STEP 2 Take a bunch or brown hackle fibres and mount on top of the shank.

STEP 3 Catch in 3 Peacock herls and wrap the thread to the shoulder.

STEP 4 Apply a cote of varnish to the body, then after twisting the Peacock Herl into a rope wrap it over the wet varnish.

STEP 5 Wrap the rib and tie off. Then invert the hook in the vice and attach a bunch of brown fibres for the beard hackle.

STEP 6 Turn the hook the right way and tie in one strand of pearl Mylar on each side of the hook.

STEP 7 Tie in a further three strands of Peacock Herl for the thorax and wrap towards the eye, then trim off the waste.

STEP 8 Pull the two strands of pearl Mylar towards the eye, parallel with the hook shank and tie off. Form a neat head whipfinish and varnish for the completed fly.

As with the standard Diawl Bach the variations are endless.
You can weight this fly if you want, but I find the added weight of the long shank hook sufficient.
I have used medium Mylar because I prefer a subtle flash, if you wish you can use wide Mylar or use Red Holographic or Red Glo-Brite (or anything else that takes your fancy)
