Figure 4. Body length is strongly correlated with body weight (here transformed to the same dimensional order as the cube root of dry weight).

When all species were combined, weight⁻³ increased slightly faster than length (log log slope = 1.12). Thus, after adjusting for dimensions, larger workers were somewhat heavier than small ones, suggesting allometries or changes in density not apparent in BL. However, whereas the majority of the species were positively allometric, some were isometric (see text).
