Climatic variables for each population and the mean detection distances for prey and background vertical targets (leafy vegetation edge). Detection ranges calculated from the method of Stilz and Schnitzler  (http://22.214.171.124/~peter/calculator/range.php webcite). The size range of prey taken by R. capensis at De Hoop is 2-19 mm  and this covers the range of small, medium and large prey in . Climatic data were obtained from the nearest weather stations and provided by the South African Weather Service.
