Figure 28. Developmental stages of Phidippus princeps from Greenville County, South Carolina. 1, The first emergent or freeliving stage (instar II) is black, with pedipalps and legs that fluoresce (emit bright yellow-green) in near-UV light. 2, The pedipalps and proximal segments of the legs of early instars like this one also fluoresce, but the face now has a cover of setae, including a darker band through the anterior eye row, typical of later instars through the penultimate stage. 3, At the prepenultimate stage males and females are similar. 4, Penultimate male, with distinct enlargement of the pedipalps but otherwise coloration like that of the female. 5, Penultimate female. 6, Adult female, with bright white setae covering the face, highlighting the anterior eyes.
