Figure 4. Phylogenies of Pheidole (A) and Pogonomyrmex(B), along with scatterplots (C and D) showing the relationship between sexual size ratio (gyne/male size) and worker size ratio (largest/smallest size). Graph insets are plots of phylogenetically independent contrasts between sexual size ratio and worker size ratio. Point size is proportionate to worker ratio and color is proportionate to sexual size ratio (lighter color is larger).
