A fast to tie mayfly dun pattern made out of CDC. It floats very well and is durable. I like to fish it in semi-fast running water. Micro fibetts, 2-4 CDC feathers (colour of your choice)  and a bit yarn, that’s all you need. I don’t know who invented this pattern, but I think it was Marc Petitjean.

Materials:

• Hook: Maruto D04 BL # 12
• Tail: Micro Fibetts
• Abdomen: CDC Feather
• Thorax and Wing: CDC Feather, Yarn

 

Tie in a loop of thread and 3 micro fibetts. Split the fibetts with the 2 piece of thread after cutting the loop.

 

Tie in a CDC feather with the tip first. Twist the feather and wind it around the shank. Then cut all little fibres, so that you’ve got a nice tapered CDC body.

 

Tie in a piece of yarn.

 

Preparing the CDC

 

Split the thread and put the prepared CDC in the gap. Then spin the bobbin to twist the CDC and the thread.

 

Wind the twisted CDC around the hook and pull it up with your fingers after every turn.

 

Seperate the the CDC with the yarn, to create the two main wings of the mayfly. Catch the yarn with the thread.

 

I like to fold the yarn back again, tie it in and cut it, so I make sure I’ve got a nice free hook eye.

 

A whip finish to secure the fly. Take your scissors…

 

…and cut the fly in shape. That’s it! If you tied some of them, you need less then 4-5 minutes to tie it.
