Abstract: A method for converting an ordinary hunting arrowhead into an arrowhead that can be used to track a game animal wounded by the converted arrowhead. The method includes the steps of filling a frangible container with riboflavin powder and then attaching the container to the tip of the arrowhead to produce the converted arrowhead so that if the converted arrowhead is fired at and hits a game animal to wound the game animal, the frangible container can break so that the riboflavin powder is distributed into an environment where said animal was hit and into any blood flowing from said wound to better enable the tracking of the wounded animal.

Abstract: A frangible container to be attached to the tip of an arrow, the container containing riboflavin so that when the container is attached to the tip of an arrow and the arrow is fired at and hits a game animal to wound the game animal, the frangible container breaks so that the riboflavin is distributed into the environment where the animal was hit and into the blood flowing from the wound so that the environment where the animal was hit and the blood trail from the blood flowing from the wound can be more readily detected by directing light having a wavelength in the range of from about 300 to about 500 nanometers to observe the resulting florescence of the riboflavin in the environment where the animal was hit and in the blood trail. In addition, a combination of an arrowhead and a frangible container wherein the frangible container is attached to or contained within the arrowhead.
