Artificial flies are of several types; some imitating an insect (either flying or swimming), others a bait fish or crustacean, others attractors are known to attract fish although they look like nothing in nature. Flies can be made either to float or sink, and range in size from a few millimeters to 30 cm long; most are between 1 and 5 cm.
