How to tie it
Start black thread on the Hanak 480 jig and form a short hot orange thread tag at the bend as the tail, a small bright anchor at the rear of an otherwise natural fly.
Tie in a hand-stripped peacock quill by its fine end at the bend. Before wrapping, run a thin film of superglue along the underbody or plan to coat the finished body with UV resin. Stripped quill is beautiful and fragile and will not survive a fish uncoated.
Wind the quill forward in touching turns to the 65% mark, letting each turn just meet the last so the natural dark-light banding reads as segmentation.
Coat the quill body with a thin layer of UV resin and cure it, which armours the body and deepens the banding at the same time.
Dub a short thorax of natural squirrel behind the bead position, spiky rather than tight.
Take one turn, no more, of long-barbed wild mallard CDC as a collar and sweep the barbs back so they trail well past the hook bend. Those long barbels are the octopus: they move constantly even when the fly is held still.
Whip finish. Fish it in medium or slow water where you can hold the nymph almost stationary and let the CDC do the work, active fish rarely resist it.
