How to tie it
Set a 3/32 brown magic bead on a size 14 curved nymph hook and load Veevus Body Quill straight into the bobbin, on this pattern the quill is the thread as well as the body, which is how the fly stays so slim.
Tie in five or six strands of grizzly Crystal Flash in copper and black at the front and wrap back to the bend, then give one pull underneath to prop the tail up and trim it to roughly a body length. The two-tone barring reads as a mayfly's three tails.
Tie in small copper wire at the back, leaving a tag pointing forward along the side so you can wrap over it and keep the underbody dead even.
At about the 75% mark tie in one strand of ostrich herl on each side, with as few wraps as possible, and let them trail out the back. These become the abdominal gills. Look at a natural and you will see exactly these breathers running down the flanks.
Build the body forward with the Body Quill to a slight taper, half hitch and disengage it, then tie in rusty brown 70 denier. Pull each herl forward along its own side with one loose wrap each, then a securing wrap once they are placed.
Rib the copper wire forward, feathering it through the herl a little at a time so the fibres stay proud rather than getting crushed. That is what leaves the gills standing off the sides while the body stays pencil-thin.
Tie in brown scud back, dub a short chocolate brown Ice Dub thorax, pull the wing case over and whip finish before you cut the stretchy material so it cannot unravel. Put UV resin on the wing case, cure it, then rake the thorax out with a brush. The picked-out Ice Dub is the legs, so none get tied in.
