Fly lure in the context of Fly tying

A fishing lure is any of a broad category of inedible, artificial fishing baits designed to be "fake food" that mimic the appearances of prey and thus attract the attention of predatory fish when angling. Lures come in many shapes and designs that impart different actions and vibrations, which appeal to fish's foraging/territorial instincts and provoke them into striking. Lure color, brightness or the metallic shine/flash alone may also contribute to fish striking a lure, but much of the time even clear hard or soft plastic lures will get struck as well as those made of fur, metal, wood, soft and hard plastic or skirts made of feather, rubber or silicone strands. Lures can be commercially made and purchased from tackle shops, or hand-made by anglers (as in the case of hand-tied fly lures).

Fishing lures are attached to a fishing line, and attached to at least one hook (commonly a treble hook). When lure fishing, the angler use a rod to cast or simply drop the lure to an area of water and then steadily retrieve the lure back, in the hope that lure movements and splashes against the water current will entice nearby fish into striking. Typically, the line is stored on a reel spool and cranked back in retrieval, but in handlining and ice fishing the line might be pulled by hand or tethered directly to a very short rod. Trolling or dragging a lure behind a moving boat is also an effective way to cover water and provoke fish to strike. The retrieve of a lure is as important as the lure cast and there are many types of retrieves, most are tailored to the lure, how it is used and where it is placed, i.e. what depth and/or near objects in the water such as plants or docks. Lures are search tools that find fish apt to strike something they have no clue is dangerous.
