 At first, these artificial fly patterns were largely derivations of existing trout and salmon flies.As time went on, new fly patterns were specifically developed to fish for bass, as well as heavier spinner/fly lures that could be cast by the baitcasting and fixed-spool casting reels and rods available at the time.Floating wooden lures (plugs) or poppers of lightweight cork or balsa were introduced around 1900, sometimes combined with hooks dressed with artificial fur or feathers.
