Hot spot Glo-Brite thread, tangerine (1 strand, doubled twice)
Counter-rib 6X monofilament (1 strand)
Rib Pearl tinsel (1 long strand)
Body Brown dry fly dubbing (the tiniest amount)
Wing EX Caddis hair, stacked (a pencil-width bunch)
Indicator post Para Post, hot pink (1 small bunch)
Collar CDC (half a large feather in a dubbing loop)
How to tie it
Mount the dry fly hook, start the thread, run it back a little and trim the excess, then take it back to where the barb would be and forward again to about the three-quarter mark.
Fold a piece of tangerine Glo-Brite thread over, wrap it round the tying thread and set it on top, doubled twice, so four strands, which locks it in fast and stops it pulling out. Run the thread back to the barb point and trim the Glo-Brite short: this is only a small hot spot at the tail.
Tie in a piece of 6X monofilament and wrap well over it. It is slippery, so make sure it is properly locked in.
Tie in the pearl tinsel for the rib. Cut these pieces long; they are much easier to handle that way. Push the thread all the way back to the Glo-Brite.
Dub the smallest amount of brown dry fly dubbing onto the thread and build a slightly tapered body forward, leaving plenty of clear shank at the front, the head of this fly builds up a lot of bulk and needs the room.
Rib the pearl tinsel forward, tie it off and trim.
Counter-wrap the monofilament forward in the opposite direction to the tinsel so the ribbing survives the fishes' teeth, and secure it.
Cut a pencil-width bunch of EX Caddis hair, comb the underfur out and even the tips in a stacker. Measure it against the tail length, switch hands and cut the butts off right where you are pinching.
Set the wing on with a pinch wrap over the tips, then wrap tightly over the butts so it cannot spin.
Tie in the hot pink Para Post as an indicator, pull it back, wrap over the top to secure it and trim it just shorter than the wing, tidying up any stragglers. This step can be left out if you do not want the indicator.
Spin a dubbing loop and set it aside, then dub a little more brown dubbing on the thread in front to cover the thread base, the collar needs something to sit on and the wing needs something to come through. Put in a two-turn whip finish here so nothing comes undone during the next step.
Cut the tip off a large CDC feather, use half of it, jam it into the dubbing loop, trim carefully and spin it up. Pick it out with Velcro.
Palmer the CDC forward, keeping it buggy with plenty of fibre and movement, capture the loop and trim.
Whip finish once or twice at the head, trim the thread and check no fibres are overlong.
