Part one of this study of the Flinders Ranges scorpion Urodacus elongatus (Scorpionidae) described instar number, sexual dimorphism, and sex related movement and survivorship. Six instars were determined for both sexes, with individuals allocated based on morphometrics. Persistent sexual differences enabled differentiation in second to sixth instars. Sexual dimorphism slowly developed in immature instars, and was fully expressed in sixth instars. Dimorphism of metasomal segments supported sexual selection for this trait. Intersexual differences in frequency and activity in sixth instars...
