Many predators exploit the chemical signatures of prey when foraging. We present a comparative study designed to test if the foraging behavior of Phidippus audax (Hentz 1845) is manipulated by substrate-borne chemicals left by prey. Our findings suggest that foraging P. audax do not use chemical cues left by prey, while the wolf spider Pardosa milvina (Hentz 1844) in the same experimental setup does respond to chemical cues. However, further examination into the role of chemical cues on prey detection in salticids is required.
