A fly is a hook, dressed with conventional fly tying materials. The affixed materials may be natural or synthetic.
Tied in conjunction with other materials, the following items may be part of the fly: wire (lead or other metal) used
for weighting the fly, dumbbell eyes or beads (metal, glass or plastic). A fly is not a hook to which sinkers, molded
weights, spinners, spoons or similar attractors are attached
Meanwhile, I think Wyoming has the worst definition of an artificial fly...

Artificial Flies and Lures
means manmade flies and lures. Artificial lures include spoons, spinners and plugs made of metal, plastic, wood and other nonedible materials, or plastic products made to resemble worms, eggs, fish and other aquatic organisms. Artificial flies includes flies, streamers, jigs, and poppers tied from such materials as thread, feathers, hair and tinsel. Artificial flies and lures does not include living or dead organisms or edible parts thereof, natural or prepared organic food stuffs, or chemical attractants.
So by Wyoming's definition, a fly is a fly, but also a streamer, jig, or a popper tied from a vague list of materials. :) I guess that's the key. A fly is a fly if it is tied to the hook! :)
