Davy Wotton’s Hatching Caddis Pupa
(Finished fly pictured below.)

This pattern is tied to imitate the hatching caddis pupa. It should be fished in the surface film when trout are taking the naturals. It is also a fly that will take fish at depth, if the hook is weighted prior to the body being dubbed.

Hook: Partridge GRS12ST Gray Shadow emerger/nymph hook size 8-18.
Thread: Danville’s flymaster prewaxed.
Body: To match natural: SLF Master Class.
Rib: Gold Oval.
Wingcase: Raffine to match body color.
Hackle: English partridge dyed to suit body color.
Wing: A soft mobile body fur is required. It may be natural or dyed hare fur from the mask, or rabbit-body fur.STEPS

  1. Dub 2/3 the distance from the starting point to the hook eye and wind the ribbing the opposite direction of that of the body.
  2. Attach raffine about 5 to 8 mm in width trailing back.
  3. Tie in fur in close, butted to the raffine and trim excess. Dub thorax with the same dubbing used in the body.
  4. Tie in a dyed partridge hackle. Take two turns of hackle and trim the excess.
  5. Using the left forefinger and thumb, hold the raffine upright. Carefully divide the hair wing to left and right sides of the wingcase. Now, bring the raffine forward to the hook eye. Before you bind it down onto the hook, make sure the partridge hackle is equally divided left and right. You will now see that as tension is applied to the wingcase it will cause the hair wing to splay out at right angles to the fly body. Secure the raffine, trim excess, build a neat head, whip finish and apply head cement.
