Notes: Biots are the stiff barbs found along the leading edge of a primary flight feather. They are necessary to give birds flight. There are only two birds that fly tiers utilize biots, Turkeys and Geese. The goose biots are shorter and wider than turkey and are often used for tails on stoneflies and wingbuds. For bodies, Goose biots can be used on Mayfly patterns in the #16-20 sizes. Turkey biots are much longer and often will be a good choice for mayfly patterns in sizes 10 to 14. For patterns smaller than #14, Turkey biots are too large and other materials such as stripped quills will work better. Turkey Biot Quills are sold as entire feathers and the "lift" side of the feather can be used for bodies but the barb is softer and thinner than the biot side. These barbs are suitable for use on sizes #16-22 but protect them with a layer of glue such as Zap-a-gap or Loons Clear Finish. |
