Genes with stage-specific differences. Average quantities as determined by qPCR for genes with significant eye expression differences between stages. Ec-so15 showed higher expression in older male juveniles, when compared to younger male juveniles. Phototransduction genes ec-calx, ec-ops, and ec-plc all exhibited higher expression in adult males compared to at least two other stages. All four genes showed significant variation by ANOVA (Additional file 9). Error bars represent standard error. Specification gene homologs are in blue, and phototransduction gene homologs are in orange. Lighter colors denote earlier developmental timepoints. Due to the large variation in expression levels between genes, the Y-axis is log-scaled
