Moose

Moose hair is popular among fly tyers who routinely construct large dry flies — Moose body hair is often used as a wing material on such patterns.

Moose Mane in comparison is much longer hair and not quite as stiff.  It is often used as a tail and body material on large extended body dry flies.  Another interesting use of Moose Mane is as a substitute for stripped hackle quills when making quill bodied flies.
