Experimental design. Local adaptation experiments were conducted at three sites: Rondeberg (R), De Hoop (D) and Pringle Bay (P). Three experiments were conducted: a low range overlap comparison (sites were 113 km away from each other) between C. uncinatus using M. digitata at Pringle Bay and W. incurvata at Rondeberg (top panel), a moderate overlap comparison at De Hoop between C. uncinatus using M. spathulata and E. nuda (middle panel), and a high overlap comparison at Pringle Bay between C. uncinatus using M. digitata and H. aristatus (bottom panel). Range overlap between restio species used in each experiment is shown in the bars to the right. Restio culms with sheaths are illustrated together with associated C. uncinatus ecotypes (smaller males are shown to the right of females). Restio sheath colour and ecotype colour of cartoons were obtained by spectrophotometer and converted to median RGB values for visualisation on a computer screen in human vision. Insects and plants were approximately drawn to scale
