Hadrurus arizonensis is a large, long-lived species of North American desert scorpion with lengthy, stereotyped courtship behaviors that lead to sperm transfer via an external spermatophore. Courtship and mating behaviors in H. arizonensis and other members of the Iuridae family have not been described. H. arizonensis has reproductive behavior similar to that of other scorpions, including the promenade a deux, but with some unique components described here for the first time. Courtship and mating behaviors of H. arizonensis are presented in a flow chart to emphasize its stereotypical nature and suitability for experimental manipulation in field and laboratory studies.
