Figure 6.
Size of six body parts measured on specimens of V. soror workers and gynes, and forewings of males. Characters compared included (A) head width, (B) thorax width, (C–E) widths of metasomal tergites 1–3 and (F) forewing length. Workers were collected from N1–N3; gynes and males were present in N2 only. Sample sizes and outcomes of one-way ANOVAs are provided in Supplementary Table 1 . Body measurements are shown in Supplementary Figure 2 . Asterisks indicate a highly significant effect of caste/sex on size in all cases (P < 0.0001); letters indicate differences between means within each panel according to Tukey HSD tests.
