TBH collared adams nymph

 

Designed to imitate a caddis grub this fly has additional weight so that it can be fished bouncing along the bottom or close to the bottom. It is very easy to tie and whilst it is not tied to represent any particular caddis grub it has a form and function and of course the hot spot added by the collar which are attractive to fish.

Materials

 

Hook Thread Weight Tail Rib Body & thorax Collar
Tiemco 3761 size #8 to #14 Grey or light brown TBH + lead wire Ginger hen hackle fibres Fine copper wire 75/25 hares ear and grey UV dubbing UV dubbing or floss

Process

 

A
  1. Most beads have a large opening at one end and a smaller opening at the other. Slide a copper tungsten bead over the point of the hook small opening first and position it behind the eye of the hook.
  2. Wind the thread in touching turns to the bend of the hook.
  3. If your going to add extra weight do that know . . . I always do because I want this fly to sink quickly and stay in the zone longer. Note that I have used the lead wire to form the basic shape of the fly but have left room behind the bead to allow for the collar.
  4. Tie in a tail equal 1/2 to 2/3 the length of the hook shank. Resist the temptation to make the tail too bulky and too long.
  5. Tie in a length of copper wire.

 

B
  1. Dub on a body starting at almost nothing and gradually increasing in width along the rear half of the fly.
  2. Wind the wire ribbing along the dubbed body of the fly forming 4 or 5 segments.
  3. Tie the copper wire off behind the bead and break off the excess wire.

 

C
  1. Using the same dubbing mix dub on a thorax, that is slightly wider than the body, between the body and the bead being careful to leave room for the collar.
  2. Take a piece of Velcro and tease out some of the dubbing from the thorax to represent legs.
  3. Put a little colored UV dubbing onto the thread.

 

D
  1. Wind the UV dubbing between the thorax and the bead to form the collar.
  2. Tie the collar off and trim the thread directly behind the bead head the bead.
  3. Whip finish behind the bead head and varnish the thread behind the bead and the bead itself. If you don't varnish the bead it will tarnish quite quickly.
