Have used small Cicadas ripped as an attractor for Perch at times. They tend to be a curious fish that will check out bottom noises/movement, sometimes they will hit the Cicada but usually will hit the juicy little bobber fry jig thats a foot or 2 away looking helpless. Doesn't seem to work as well on gills or crappies but have caught some of my nicer ones on really slow days doing this.
