Hi Charlaine,
You certainly do not have to have all of the stuff found in pattern books. Substitution is fairly standard procedure. The key is to understand what different types of materials can be used for different applications.
In this case, calf tail (also known as Kip tail) is often used for winging and tailing dry flies. If the color needed is white, then the white portion of a bucktail will work just fine. If dyed color is needed, then dyed buck tail will again work just fine.
Polar bear is a problem. Because of the endangered species act, it is almost unavailable in the US. It is still available to some extent in Canada, to my understanding. In this country it can be had in the form of old rugs or perhaps coats that were shot before the endnagered species act and other similar items. Such sources are extremely difficult to come by. Where good quality polar bear of this type can be found, it often makes it’s way into fly shops. There it is VERY pricey IF you find it.
The attractive quaility about polar bear is it’s transparant/translucent qualities. Polar bear hair is essentially colorless and hollow so as to transmit the sunlight that falls on them down to the skin where it is absorbed as heat to help keep the bear warm. It looks white on the bear, but is not, instead being colorless, so other natural types of white hair are not a good substitutes.
The transparent qualities polar bear has are extremely desirable but can not be matched very well by any natural hair, as far as I have been advised by some very knowledgable tiers. (I don’t have any real polar bear, as it is too pricey for me.) I have been advised of prices at a minimum of $10 and more per square inch.
Substitutes have been developed, because the real thing is so expensive and hard to come by. These are primarily made from synthetics. One such substitute is Ronn Lucas’s Irridescent Dubbing. I have used it, it is good stuff, and it is effective. There are other substitutes as well. The down side is that none of the substitutes are not easy to tie with, but I have been advised that the real thing is also a bit of a pain to tie with.
Hare’s ear is used for dubbing of such flies as the gold ribbed hare’s ear nymph, and other flies. You can find it in fly shops as packaged dubbing for a couple of bucks. The other option is to buy a hare’s mask (the hide from the head of a European hare), trim the fur from it, and mix it thoroughly. A hare’s mask generally runs about $5. When I make my own dubbing from a mask, I trim the ears and all of the fur except the really light color cheek patches. You can trim the cheek patches separately and use it for lighter color dubbing.
However, I have also mixed other fur types, that had colors similar to that of the various parts of the hare’s mask, and made a hare’s max substitute that was extremely similar to the real thing.
Moose mane is on the top of the moose neck, and consists of long hair some of the hairs being black and some of them being white. The typical use of moose main is for the body of a mosquito pattern. It often works better in use if the moose mane hair is made damp prior to winding on the body of the fly. It can have a tendancy to break if not dampened prior to use. I have used porcupine guard hair, of the proper colors, in place of moose mane. It stands up very well, much better than the moose.
When I took a fly tying class many years ago, my fly tying instructor used white plastic fiber from coarse plastic twine in place of moose hair for the white portion of the body. I think he may have used black thread for the black portion of the body. To do this, he first wrapped the hook shank with black thread after tying in the tailing. This was followed by ribbing the body with the white plastic. He claimed it worked very well, and stood up to fishing much better than did the moose mane.
At any rate, the key to substitution is to understand the use of the material in the pattern, and then to know what materials will work similarly to the material that is called for.
As I and others have mentioned, substitution is very common in fly tying. This is the case in tying your flies, and also in flies that are comercially tied for fly shops.
