Fly tying hair can be broken into two main categories: Big Game and Small Game. Big Game animals include; Elk, Deer, Bear, Caribou, Moose, Antelope. Small game animals include; Fox, Squirrel, Rabbit, Skunk, Badger, Woodchuck, Mole, Nutria, Beaver, Muskrat, Mink.
Most Big Game animal hair is used for winging materials. Some is hollow and very buoyant, while others are solid fibers, or mostly solid fibers that are best suited to wet flies. Hollow big game hairs are often used for body materials as well. When spun or stacked, then clipped to shape, the result is a high-floating fly – most often seen in hopper patterns, muddler heads, bass poppers and steelhead skaters or bombers.
