Distribution overlap between C. uncinatus and its hosts. Known distribution ranges of C. uncinatus (C. u – empty dots) and restios used by it (black dots). These are: Willdenowia incurvata (W. i), Willdenowia teres (W. t), Mastersiella digitata (M. d), Mastersiella spathulata (M. s), Hypodiscus aristatus (H. a), Hypodiscus synchroolepis (H. s), Elegia nuda (E. n), Elegia stokoei (E. s), Elegia muirii (E. m), Elegia. fistulosa (E. f) and Elegia filacea (E. fi). Fractions show how many times a restio species was used by C. uncinatus out of the number of times that the restio species co-occurred with C. uncinatus in our dataset (Additional file 1: Table S1). The bar on the right shows the proportion of the range of C. uncinatus overlapping with each restio species (indicated with tick marks which correspond to small individual bars in each panel). The grey portion of the bar shows bootstrap determined mean overlap across restio species with an upper 95% confidence interval
