Fly Tying the Pale Morning Dun (PMD) 

 NymphRight.gif

This fly is an effective May Fly pattern that represents the Pale Morning Dun (PMDs).  PMDs hatch in June and July on the Bow River.  They are often an over-looked pattern as the heavy hatches occur in June right in the middle of spring run-off high water.  The fly should be tied with minimal materials to keep it as light weight as possible.   The under hackle is trimmed to allow the body to sit flat into the water surface film.  This PMD can be tied in many colours including olive, rust, brown, black, and grey.  

 Materials

  1. Standard Straight Eye 12-18 Dry Fly Hook 
  2. Pale Yellow (Cahill) Thread size #8
  3. Light Tan Antron Wing Post
  4. Cream Dun Hackle Tail
  5. Pale Yellow (PMD) Dubbing for body and thorax/head.
  6. Cream Dun Hackle

 Tying Instructions  
PMD_1.JPG Pinch the barb and lay down a good base of thread
PMD_2.JPG Attach a sparse clump of cream dun hackle barbs for the tail and tie them in so they fan out a bit.  The tail should be as long as the body of the fly.  Use the tying thread to create a smooth body. 
PMD_3.JPG Attach a sparse amount of light tan antron yarn.  Notice that the wing post is at about 2/3 up the shank of the hook.  It is important, as always, to proportion the fly. Leave room for the hackle and the thorax/head of the fly. 
PMD_4.JPG Attach the hackle feather.  The hackle is attached slightly back from the wing post.
PMD_6.JPG Run the tying thread to the rear of the hook and twist in a noodle of light yellow (PMD) dubbing.  Wrap the dubbing forward and stop just past the wing post. 
PMD_7.JPG Wrap the hackle forward just past the wing post.
PMD_8.JPG Dub in another small noodle of light yellow (PMD) dubbing.  Form the thorax/head of the fly.  Put 3 or 4 half hitches in to tie off the head.
PMD_9.JPG Cut the wing post so that it is slightly above the hackle barbs.
PMD_10.JPG Clip the bottom hackle barbs even with the point of the hook.  This will help the fly to sit flat in the surface of the water.
