Figure 2.

(a) Males (orange, n = 43) exhibit positive allometries; larger males produced proportionally heavier weapons for their body size than do small males. In comparison, females (grey, n = 15) did not exhibit positive allometries in hind leg mass. (b) RMR for insects with all legs intact exhibited positive allometries in males, while female RMR had no significant relationship with body mass. The mass of a single hind leg was used in all estimates of hind leg mass. All lines were generated from OLS regression linear models. Each point on the graph represents a single measurement from each individual. (Online version in colour.)
