Fig 2. The morphospecies richness and abundance per insect order.

Total morphospecies richness (black bars) and abundance (grey bars) for each insect order captured during vacuum sampling surveys of Restionaceae communities across the Cape Floristic Region. Hemiptera dominated herbivore communities on restios. Only herbivorous insects are included. The mean (± SD) insect morphospecies richness for plots was 9.47 ± 4.76 (range: 0–27), for squares 29.25 ± 10.09 (range: 12–60), for sites 44.80 ± 12.80 (range: 26–70), for clusters 126.17 ± 9.06 (range: 118–144) and for mountains 192.67 ± 22.55 (range: 171–216) (Table 2).
