From: Diversity begets diversity: host expansions and the diversification of plant-feeding insects
Phylogenetically independent contrasts generated by MacroCAIC. The figure shows species numbers of the clades connected by the independent contrasts in host plant diversity found by MacroCAIC. There is a positive correlation between host diversity and species richness; clades with a higher host diversity index also had significantly higher species numbers. Means ± SE.
