There is usually a spool of dapping floss lurking somewhere in my bag. I rarely dap but just in case I feel the need or someone else in the boat requires some, a reel of the light brown floss is on hand. As I was tidying up my gear today I unearthed the spool and took a good look at it. It occurred to me the floss might be a suitable material for a dry mayfly so I snipped a piece off and started tying.
Using a Kamasan B170 size 10 hook, I started the 8/0 chartreuse silk near the bend then ran it up to about 4mm from the eye. Here I secured the floss with figure-of-eight turns, creating two wings which I then trimmed to roughly the same length as the hook shank. Now I tied in a chocolate coloured genetic cock hackle. Next, I tied in a bunch of natural brown squirrel tail hair, cutting off the waste and binding it in as I ran the tying silk to the bend of the hook. Here I tied in a length of thick brown silk which would be used as a rib before dubbing the silk with natural seals fur. The body was formed by winding the dubbed silk up to near where the wing were tied in and I ribbed the body with the brown silk, then removed the waste. The hackle was given multiple turns both behind and in front of the wings before tying it off, removing the waste end and forming a neat head with the tying silk. Whip finish and varnish was all that was needed to complete the fly.
The mayfly is nearly over for this year now but I will save this new pattern for next spring. Over the years I have given away almost all of my dry mayflies. A few Wulff’s and my favourite CDC Emergers are just about all that I have left so this coming winter I will make the effort to tie a box full of dries.
