Toy butterfly, essentially characterized by being constituted by a frame composed of two long lanyards or parallel rods, joined at their ends to two transverse bodies, forming with them a frame, inside which are housed the rubber propeller rings fastened on hooks, having, also in the previous body, two other rods or lanyards intended to serve as a support, together with the aforementioned frame, of a very thin sheet, duly attached to said support, having in the front part of a body attached to the end of the rod of the hook of winding of the rubber, from whose body two long rods with their ends bend at an angle, imitating two large antennae of a butterfly serving such support rods of the corresponding thin sheets to form two blades in the manner of a propeller, turning slightly the plane of one blade with respect to the other.
