Silhouette:
The outline or general appearance of a dry fly perched on the surface film as it appears to the fish. Should present a likeness of the insect being represented.

Wings usually make of hackle tips, sometimes of feather sections or hair. Simulate the wide spread wings of dead spinners and drakes. Usually applied with one or two wings out each side of thorax.

Spey:
Method of tying certain salmon flies, the most distinguishing feature of which is the palmered hackle tied in at the tail by the butt end of the hackle, then spiralled forward ending up at the head with the smaller or tip end of the hackle, making the fibers longer at the rear end and shorter near the fly front.

Spey Hackle:
Another name for saddle hackle of a soft nature. Originally Spey hackles came from the side tail feathers of a rooster. Substitute most any long fibered soft hen hackle. Colors vary with dyes used. Heron hackles often used in "Spey" flies.

Spey Wing:
Type of wing applied to "Spey" salmon flies. Matched short pair of feather sections placed in a near flat, tent type, close over fore-body, extending to hook bend, but not beyond. Usually of Bronze or Brown Mallard with slight graying at the butt ends.

Spider:
Specific tie of a fly pattern wherein the hackles are over-sized, even two or three times larger than normal. Flies tied in this manner can be skittered across the surface, or the wind will blow them.

Spike:

Sprig:
British term. A feather or hackle fiber or fibrils.

Spring:
A Dee type tie with wings slightly divided. Normally refers to salmon flies.

Spring Salmon:
A Dee type of tie, wings are slightly divided.

Spun Fur:
Furs in various shades and colors can be purchased from suppliers. It appears like yarn or wool. Eliminates time consuming blending and dubbing.

Spun Wool:
A commercially made wool yarn especially for fly tyig. A better grade of wool with longer fibers than ordinary yarn.

Squirrel:
Red, Fox, Black and Gray squirrels provide tails which are a standard in the fly tier's kit. Comes in grays, browns, and blacks. Some have white tips on the hairs. Used mainly as winging material, especially in streamers.

Stacked Fur Dub:
Formation of a ball or succession of balls of fur and piling them one on top another to form a high or built-up thorax. Balls are formed by alternate horizontal and vertical spinning of fur on dubbing thread.

Starling:
Super gray feathers with lighter markings come from this bird. Used in wings for small wets and drys.

Stiletto:
See - Bodkin.

Stillborn Flies:
Insects only partially out of the nymphal case during a hatch. Appear to be stuck at some stage of emergence. Two basic forms are found:
    1. Free wing - both wings are clear of shuck, but abdomen is still encased.
    2. Trapped wing - one or both wings are still encased in the shuck.
Usually these are noticed dead or nearly dead from their struggle to emerge. Trout appear to recognize the plight of these would-be emergers and feed freely on them.

Stoat:
Term given to the summer coat of the Ermine or Weasel, which in summer is creamy to brownish-white. The winter coat is vey white. The tail tip is black all year.

Storage:
Keeping of fly tying materials, especially furs, hair and feathers safely is a problem of all fly tyers. Recommended use of air tight or plastic bags or tins. Use moth flakes, napthelene, borax or some insect repellent to keep out moths and their destructive larva.

Straddle Bug Style:
A fly tied in reverse. Head and hackle at the bend of the hook and tail fibers at the eye of the hook. British usage.

Straw:
Grass and grain straw is used sometimes for fly bodies. Not very durable, it should be ribbed with wire or tinsel or thread for strength. Comes in many colors and has a special sheen not found in other materials. Flax straw is one of the strongest and most pliant.

Streamer Fly:
A fly with hackle wings, representing a baitfish.
See also - Bucktail Streamer and Bucktail Fly.

Streamer Jig:
Lightly weighted at the head only, streamers which may be fished in a dip and rise fashion simulating feeding minnows. Developed by Joseph D. Bates Jr. and Loring A. Dodge.

Strip:
Small section of wing feather inserted in middle of fly wing to simulate the mid-line or median-line of bait fish. A contrasting color dividing a wind.
See - Split. Used mainly in salmon and steelhead flies.

Stripe:
See Strip and Split.

Stripped Herl:
Ostrich or Peacock herl which has had the flue removed. Stripped herl is used to make quill bodies on flies like the Mosquito. Also used to simulate feelers and antennae.

Strip Wings:
Two matched sections of wing or tail feathers mounted as a pair on a fly. Example: Matching sections from a Turkey feather from each wing of the bird, so that lengths and curvatures are as near opposites as possible. These sections may be mounted back to back to form a closed wing, or may be mounted from front to front to form splayed or divided wings.

Strung Hackle:
Commercially prepared hackles selected and bound together with a string binding - strung. Care must be taken by the purchaser to examine the hackles to see that a fairly equal amount of right and left feathers are included, as some strings come with all of either rights or lefts, and do not lend themselves to happy tying.

Style, Fly:
Describes generally the outstanding feature of a fly, as, hairwing, downwing, feather wing, parachute, all hair, silver body, or no hackle, etc.

Sub Imago:
Stage of a Mayfly when just emerged from the nymphal case. A burdensome, dull colored stage. Flight is sluggish and usually toward streamside wooded area. Also call - Dun.

Substitutes:
Any like or similar materials may be substituted in fly patterns. Some examples are:
  • Silk floss - Nylon floss.
  • Natural colors - Dyed colors.
  • Barred or speckled feathers - A similarly marked feather.
  • Special pattern feather - Pantone marked plain feather.
  • Natural furs - Synthetic furs.
  • Woodchuck hairs - Chipmunk tail.
  • Jungle Cock eyes - Lacquered and painted hackles.
  • Furs - Man-made fibers such as Sealex.
  • Hackle - Man-made fibers or hair hackles.
  • Hairs - Man-made fibers, Nylons, etc.
  • Wools - Man-made fibers, Mohlon or Orlon.
    There is no limit to imagination or improvisation in the art of fly tying.

    Substitute for Badger, Furnace, Coch-Y-Bondhu or Greenwell Hackle:
    Use a similar color feather and interwind black ostrich herl to obtain the black center list effect when applying hackling. To substitute for wings, use a solid color feather and dye-mark the black center stripe, carefully, with dye marker pen.

    Summer Duck:
    Another name for Wood Duck from which comes the lemon- yellow side speckled feathers.

    Swan:
    Swan plumage is next to impossible to obtain. A suitable substitute can be found in both wild and tame goose feathers. The side and shoulder feathers, with the rib in the center, provide matched sides for winging smaller flies, or for wing materials for salmon patterns. Often found in most any color, they take dyes easily.

    Swanundaze:
    One of the many man-made plastics. Similar to leather craft lacing. Made in round, oval, flattened forms and comes in many shades of brown, olive, yellows, etc. Used mainly as body material for nymphs and gives a good representation of segmentation.
