The Lure of Stuff: Wanting What You Can’t Have
By Tom Chandler on Nov 9, 2006 in Flies, Underground Entertainment

By Sully, Underground Correspondent in charge of arcana.
EVERYONE has a few Pheasant Tail Nymphs in their box. Frank Sawer’s deceptively simple pattern has developed a worldwide following.
Precious few anglers, though, have even heard of the Sawer Killer Bug. As with the P.T., Sawer chronicled the development, tying and fishing of the Killer Bug in “Nymphs and the Trout”.
First published in 1958, this bountiful book explains how Sawer developed the simple cigar-shaped bug to catch grayling in the upper Avon.
In that role the Killer Bug has achieved almost cult-like status in the British Isles and Europe. In grayling-poor America, however, the fly hasn’t received the recognition it deserves.
The bug was tied to imitate the creature anglers call freshwater shrimp (ammarus pleus in England).
Simple Pattern. Killer Results?
In the profoundly minimalist manner that led Sawer to omit legs from his P.T. Nymph, he left off the antennae, shiny carapace, the multiple legs and leglike appendages (gnathopods and pleopods) that spell “shrimp” to human beings.
It’s like drawing a rabbit without adding the ears. What’s left is a copper wire foundation with wool wrapped over it. That’s it.
Sawer on the obvious, “Once again this is of very simple construction, so simple indeed that anyone looking at it could be forgiven for thinking it could deceive a fish.”
There almost has to be a hitch in something this elegant. There is.
The Killer Yarn
Sawer specified that the body material for the Killer Bug had to be a particular color of mending yarn, a mixture of wool and nylon; Chadwick’s 477. He had extensively experimented and nothing else fished as well.
Nowhere in “Nymphs and the Trout” is there a description of the color of this magical yarn. The tease is that the color of the bug changes completely when wet. According to Sawer, “… it is this that causes its attraction for so many kinds of fish.”
Thanks for raising our hopes, Frank. All a Chadwick-less angler has to do is ascertain the color that’s irresistible to shrimp-eating fish when wrapped around red copper wire and wetted.
Charles Ritz fished with Sawer and became a devote of the Killer Bug. In “A Fly Fisher’s Life” Ritz writes that the bug is tied with “grey wool,” but some subtleties might have been lost in translation from the French.
Other descriptions of the blend have described it as “fawn with a pinkish tinge” and “red, brown and grey.”
Where was the Borger Color System when we needed it?
Help Isn’t on the Way
In 1958 Chadwick’s 477 was, to quote Sawer, “not very easy to obtain”. Naturally Chadwick’s immediately ceased production of the stuff, knowing that flyfishermen as a breed are particularly susceptible to the allure of arcane materials.
From the first time I first read about the Killer Bug I knew that I had to get some Chadwick’s 477.
Sometime in the late 1970’s an obscure advertisement appeared in an early issue of Flyfisherman Magazine. A company identified only by initials located in Ogden, Utah was offering the original Sawer Killer Bug yarn for sale.
The whole setup sounded perfect. An obscure group situated in the middle of the desert would be the logical source for something this arcane and powerful.
I have no idea if anyone else acted on the ad. (Maybe selling discontinued darning wool isn’t a foolproof business plan.) Maybe the illuminati simply moved to a different dimension.
My letter requesting more yarn several years later was returned by the Post Office. After a couple of decades I’m now left with just a few turns of the precious two-strand darning wool.
Substitues? Not Likely
The color? Well, it’s easy to see how Charles Ritz could stop short with the word “grey.” It’s a thatched-roof cottage, gather around a bowl of steaming gruel kind of color. 477 apparently was developed for darning knickers torn on Highland gorse. It’s easy to see why Chadwick’s discontinued the stuff: no one has worn a garment this color since V-2’s stopped raining on London.
My artist wife calls the color “taupe”: a word like “holistic” that contains no substance.
If you are one of the dozens of anglers with access to “Fly-tyer’s Color Guide” by Al Caucci and Bob Nastasi look up 4y2r3b23w. How does gray, with subtle overtones of tan describes the color? That’s the base color to the dry yarn.
When wet it does display a pinkish overtone. To the point; when the yarn is presented to fish over a red copper base it fully merits the name “Killer.”
Who Eats This Stuff?
Scudding fish, sow bug eaters, fish grubbing pre-emergent caddis, heck, fasting fish are all susceptible to the fly. Quite a few years ago a short blurb appeared in Ed Story’s Feather-Craft newsletter. It promised Chadwick’s original 477. Naturally I bit.
When the stuff arrived it was a disappointment. It was much browner that the original yarn. Too “fawny”. But we tied Killer Bugs with it and they worked, too.
Sawer tied the fly in sizes 3 through 10 using the reverse- numbered Kendal nomenclature (comparable to our Redditch sizes 14 through eight) and fished the fly for everything from grayling to, and this is both astonishing and compelling, Atlantic salmon. Locally we stick with smaller sizes, 14 down to 18. The fly is especially effective in the fall.
A few years ago Paul Redfern, the crafty owner of FishOn Fly and Tackle in Butte managed to score a few inches of certified Chadwick’s 477 from an English tier. Sure enough the stuff from Utah was the real deal.
You got some you want to send to Sully?

Hmmm, link claims 477, but the pics aren’t quite the same…

I don’t think that Waderson wool is the same. In fact I’m sure of it. Not too long ago saw some Chadwicks 477 go at an auction (small card) for a few hunder dollars. I’ve been trying to locate that info for you but so far no luck.
Here is a photo of the fly though.

Jason- Welcome to the quest! The stuff shown in your link looks like the yarn Ed Story sold. It works, but ISN’T 477.
thee trouthole- Imagine the MacDonald’s golden arches. Mentally butt up the open sides and you’ve got the proper fusiform shape. Just lay down a couple layers of reddish copper wire with the second layer shorter than the bottom one. Wrap magic yarn- Voila!
biologists and proof readers- Yes- a “G” belongs in Gammarus.

I think I have an old sport coat in that color.

Genius! Pure genius. I must have some of that yarn. I wonder if Cabelas has it?

nymphs…..an entire article on one nymph, I’m disgusted! The Underground must be running out of material I guess, I’m very sad to have witnessed this. I thought the Underground was better than this?

C4CRaine (if that IS your real name)
Here’s a quote from Bob White, a legendary wooden boat builder on Flathead Lake, that might cleanse your pallet.
“If God had wanted me to build fiberglass boats, he’d have grown fiberglass trees.”.

C4C - this isn’t just any nymph. It’s mid-20th century pattern that’s fallen into disuse and is made from unobtainable materials. It really doesn’t get a much better than that, thereby qualifying for the Underground’s rare Hackle Exemption.

I’ve come across some 4 ply tapestry wool the identical shade of 477 - I’ll tie some bugs with it and see how they fish

Mike: Let us know how it works.

How much is an unused card of Chadwick 477 worth?
I discovered 10 cards of Chadwicks with just one 477 amongst them. They were in an antique sewing box at a house auction in Norfolk (UK) where I live. The sewing box went for more money than I could afford, but after the sale, the lady who bought it was more than willing to sell me the darning wools for a fiver!!
Tom Chandler | Apr 2, 2008 | Reply
On eBay, probably hundreds.

TC and Richard,
The Chadwicks is too precious to be allowed to slip into some rich bastard’s fly tying cabinet.
There has to be a share-the-wealth Troutunderground scheme in this somehow.

We have a professional fly tyer, Phil Holding, advertising in the UK. See his web site: spidersplus.co.uk
He will tie the Sawyer Killer Bug USING REAL CHADWICKS 477 they sell at 60 pence each (about 35 cents) How does he do it?
Here is a quote from his site
“Also, in addition to patterns for both Brown and Rainbow Trout, there are flies suited for Grayling - both dries and wets, again tied to traditional recipes such as FRANK SAWYER’S Killer Bugs tied with just GENUINE Chadwick’s 477 wool and wire - and many OLIVER EDWARDS patterns such as his Deep Diving Shrimp.”
If this wool is so valuable, you should be able to buy a bunch of these flies, unravel them and flog the reclaimed 477 at a profit!
