Rib: Semperfli brown micro nymph glint

Body: Caddis green superfine dubbing

Hackle: Pine squirrel

Understandably, from time to time we all get seduced with the idea of tying exact, fanciful imitations.  Some do this as a measure of their ability and others for the sheer enjoyment of mimicking nature to the enth degree.  Personally, I’m not a great fan of the close copy school, as often the finished article lacks movement and appears “hard”(if that makes sense!).

For me, flies fashioned from soft, mobile materials win hands down every time. Granted they often appear a bit more scruffy and unkempt, but that’s part of their appeal, as far as trout are concerned anyway!  Possessing bags of movement his mobile pupa of sorts is a prime example. I say “pupa” in the loosest sense, as not only does it pass for ascending sedge pupae, but a liberal dousing of floatant sits this pattern in the surface film, just like a caddis struggling to depart its shuck.

Obviously the whole illusion hinges on wispy pine squirrel fur arranged in a dubbing loop that’s spun tight to create a durable, yet extremely attractive collar on the finished article. However, if you select a flat, multi-fibred thread, this can be carefully split and the fur inserted between the separated strands. Spinning your bobbin holder in a clockwise direction (viewed from above) secures the fur in a tight rope, which is ultimately wound like a conventional hackle.  


Step 1: Having formed the body, lightly tensioned thread is carefully divided using a fine point dubbing needle.

Step 2: Pine squirrel fur mounted in a dubbing clip is then offered up to the split thread.

Step 3: Pinching the thread tight immediately beneath the fur holds it in place whilst you spin the bobbin holder.

Step 4: Slowly releasing your grip allows the thread to twist tight and form a dubbing rope.

Step 5: Using damp fingers, squirrel fur is stroked rearwards to prevent unwanted fibres from becoming trapped as the hackle is wound forward.

Step 6: Three touching turns of dubbing rope will usually be sufficient.  Remember to leave adequate room for a neat head.
