A fishing lure is a type of artificial fishing bait which is designed to attract a fish's attention. The lure uses movement, vibration, flash and color to bait fish. Many lures are equipped with one or more hooks that are used to catch fish when they strike the lure. Some lures are placed to attract fish so a spear can be impaled into the fish or so the fish can be captured by hand. Most lures are attached to the end of a fishing line and have various styles of hooks attached to the body and are designed to elicit a strike resulting in a hookset. Many lures are commercially made but some are hand made such as fishing flies. Hand tying fly lures to match the hatch is considered a challenge by many amateur entomologists.
