CDC Mayfly

A small mayfly, which may be (mis)taken for a dun during the sometimes the concentreted hatches on late August and Septemper evenings. It uses a hollow extended body, parachute hackle and wings of cdc stems to float high.

One day I was given this fly by a friend, but I only got one.

I found it nice and convincing and decided to put it away until tying time.
During the summer 2006 I fished it in Tuscany - Italy and lost it.

A few weeks ago my job took me to Jutland where I had a meeting close to some danish streams. I spent an afternoon with Ripley Davenport (known by regulars in the GFF forum and Pix section) at the banks of one of them. As it got darker we witnessed one of the most hysteric hatches I have ever seen. Duns crawled up and down our waders. Nymphs were emerging through the surface and duns penetrated the film to get to the bottom.

Photographing in the sparse light was difficult, but we got some pictures, which inspired me to take up this pattern again - before it escaped my memory.

I know the tail and color is not realistic in this specimen, but this is a generic pattern and it will probably show it's effectivness just the same.

Nice fly! As my practice shows there is no use to make such complicated steps. I use only 2 cdc feathers for both extended body and the wing. One disadwantega - it work only for one trout and the is totally destroyed, but for many graylings)

Long story short

Support the Global FlyFisher through several different channels, including PayPal.

Long story longer

The Global FlyFisher has been online since the mid-90's and has been free to access for everybody since day one – and will stay free for as long as I run it.
But that doesn't mean that it's free to run.
It costs money to drive a large site like this.
