H. melpomene IR gene expression heatmap for sensory organs and sexes. Names of IR genes significantly differentially expressed (FDR <0.05) between mouthparts, legs and antenna are highlighted with different background colors. Most of the differentially expressed genes display higher expression in antennae than in mouthparts and legs (purple background). Only IR60a2b displayed higher expression in mouthparts and legs compared to antenna (green background). The remaining mRNAs that are significantly DE were more abundant in antennae than in legs (yellow background) or mouthparts (red background). Note the similarity in overall expression of legs and mouthparts compared to antennae. FPKM values are represented with a color gradient from blue to red. Exact FPKM values can be found in Table 4 and Additional file 4. Individual heatmaps are presented in the Additional file 5
