Nymphs That Fish
Lesson: The Pheasant Tail and Thin Bodies
okay. we did the hare's ear, which is scruffy on purpose. now we're doing the pheasant tail, which is the opposite problem. this fly wants to be thin. sparse. almost skinny. and for most beginners that's harder than buggy, because everything in you wants to add material to make it look "finished."
it doesn't need to look finished. it needs to look like a mayfly nymph, and mayfly nymphs are slender little things. the pheasant tail's whole reputation is built on being a slim, buggy, brownish profile that drifts naturally. the second you fatten it up you've lost the thing that makes it work.
so this lesson is really about restraint. which is funny for me to teach, because restraint at the vise is not my strong suit historically.
the materials
- hook, size 14-18, standard nymph hook (curved shank is fine, straight is fine too)
- thread, 8/0, brown or rust colored
- pheasant tail fibers (a handful, natural reddish brown)
- fine copper wire for ribbing
- a small ball of peacock herl for the thorax, optional but i like it
- weight, if you want it — a few wraps of lead or lead-free wire under the thorax
pheasant tail fibers come off the center tail feather of a ring-neck pheasant. if you've never handled it, take a minute before you start and just pull a few fibers off the stem. notice how they taper — thick near the stem, thin at the tip. that taper is doing a lot of the work in this fly. it's why the body comes out tapered without you fussing over it.
tying it
1. start your thread and tie in the tail. select 4-6 pheasant tail fibers, even up the tips, and tie them in at the bend so about a hook-gap's length extends past the back. same measuring principle from a few lessons ago — you're not eyeballing "looks about right," you're checking it against the hook.
2. tie in the copper wire. right at the base of the tail, tie in your wire so it trails back along the hook shank. you'll bring this forward later as ribbing.
3. tie in the same pheasant tail fibers for the body — don't cut a new bunch. this is the part people skip and shouldn't. use the same fibers your tail is made from. tie them in by the butt ends just ahead of the tail, then wind your thread forward to just past the midpoint of the hook.
4. wind the pheasant tail fibers forward as the body. twist them slightly as you wrap — this locks the fibers together so they don't split apart later — and lay each wrap snug against the last one. you should see the natural taper doing its job: thin at the back, gradually thicker toward the thorax.
5. rib it with the copper wire. counter-wrap the wire forward through the body, 4-5 evenly spaced turns, opposite direction from how you wound the pheasant tail. this is both durability and looks — the wire reinforces the fibers so they don't shred apart the first time a fish or a rock gets ahold of them.
6. build a small thorax. a few wraps of peacock herl, or just a slightly heavier build of tying thread if you don't have herl handy. keep it small. this is the one place on the fly that's allowed to be a little bulkier than the rest, because it's standing in for wing pads and legs, but small is still the word.
7. whip finish and you're done.
no hackle, no wing case fuss for this basic version. that's intentional. we'll get to wing cases and beadheads in a later lesson once you've got the plain version dialed in.
where beginners go wrong
almost always it's the thread wraps. people build up thread at the head the same way they build up everything else — out of nerves, basically, wanting the thing to feel secure. i did this on my first dozen flies, badly. every one of them had this lumpy, oversized head because i genuinely thought more wraps meant more secure. it does not. it means bulky. brittney found one of those flies two years later sitting in the junk drawer and asked me, straight-faced, if it was a cat toy. it kind of was, at that point. it wasn't catching anything else.
the fix is the same fix as everywhere else in tying: fewer wraps, tighter tension, trust the material to hold. a whip finish with three or four turns done correctly is more secure than eight sloppy ones.
my other opinion here, and i'll say it even though some people disagree: match the hatch gets oversold for our local water. on fast freestone streams like up the canyon, the fish aren't getting a long look at your fly. a plain pheasant tail in the right size and the right thin silhouette will out-fish a "scientifically accurate" mayfly imitation most days. presentation and getting it down to the right depth matters more than nailing the exact bug.
before next time
tie two or three of these and hold them up next to each other. if one looks noticeably fatter than the others, that's your thread discipline talking, and no worries at all — just go back and count your wraps next time instead of guessing.
