Fig. S1 Principal components analysis of gene expression levels. Three-letter labels identify taxonomic group (h = hybrids; i = S.  invicta; r = S. richteri), caste (M = males; Q = queens; W = workers), and developmental stage (p = pupae; a = adults). Percentages of variability explained by each component are shown in parentheses.

Fig. S2a Venn diagrams depicting numbers of genes over-expressed in pupal males, workers, and queens of hybrids (hyb), S.  invicta (inv), and S.  richteri (ric). Overlapping areas indicate differentially expressed genes common to two or three of the taxonomic groups. Circle size is proportional to the number of genes.

Fig. S2b Venn diagrams depicting numbers of genes over-expressed in adult males, workers, and queens of hybrids (hyb), S.  invicta (inv), and S.  richteri (ric). See supplementary Fig. S2a caption for additional explanation.

Fig. S3a Venn diagrams depicting numbers of genes under-expressed in pupal males, workers, and queens of hybrids (hyb), S.  invicta (inv), and S.  richteri (ric). See supplementary Fig. S2a Caption for additional explanation.
