An improved cover for a pre-existing jig-type fishing lure comprises an elastomeric membrane which conceals a greater amount of the hard, weighted head of a pre-existing jig-type lure, as compared to prior art. One or more flap elements, a thin portion of the membrane located generally opposite a mount-enabling first aperture, a second aperture located generally opposite the mount-enabling first aperture, or a combination thereof, enables the improved cover to conceal more of the weighted head. The cover can be attached to or removed from the weighted head without having to break the line of an already-tied jig-type lure. The cover also enables fluttering fish attracting elements and the generation of acoustic stimuli while the lure itself remains stationary. The elastomeric membrane can further comprise a generally concave or flat surface to enable a pre-existing jig-type lure to exhibit an oscillating-type motion when retrieved.
