TBH dark magic – Chatto’s original

 

This is a hybrid of a spider fly and a bead head nymph with a tungsten bead up front  and are particularly useful in situations where I need a bit of weight to get a fly down yet still want the anchor fly to fish well and be enticing to trout rather than just being an anchor for other flies in the team. Hybrid spider nymphs are good buggy looking flies and the tail and soft hackle provide plenty of movement. One of these hybrid spider nymphs on the top dropper and two unweighted spiders or nymphs below can be a real tease for trout.

Materials

Hook Thread Tail Rib Body Collar Hackle
Tiemco 3769 #10 to #14 Black Hackle fibres Silver wire or black holographic tinsel Peacock herl Thread Crow

Process

 

A
  1. Most beads have a large opening at one end and a smaller opening at the other. Slide a 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. Tie in a tail of hackle fibres. Take care not to make the tail too heavy 4 to 6 hackle fibres is generally enough.
  4. Tie in a length of silver wire or holographic tinsel the top of the hook shank.
  5. Tie in 2 to 4 peacock herl depending on the size of the fly and quality of the herl.

 

B
  1. Create a herl rope with the thread and peacock herl and wind it forward creating a thin cigar shaped body.
  2. Tie the herl off behind the bead and trim the excess.
  3. Wind the wire or holographic tinsel forward creating 4 or 5 segments in the body of the fly.
  4. Tie the ribbing material off and behind the bead and trim the excess.
  5. Tie a crow feather in by the tip directly behind the bead,

 

C
  1. Trim the tip of the crow feather off and take just one or two full turns directly behind the bead,

 

D
  1. Tie a single peacock herl in behind the bead.

 

E
  1. Take just enough wraps of the herl to fill the gap behind the bead, tie the herl off and trim the excess.
  2. Whip finish behind the bead. The easiest way is to do quod hitch or two.
  3. Trim the floss and varnish the floss collar and the bead itself. If you don't varnish the bead it may tarnish quite quickly.
