Bumblebees exhibit remarkable color pattern diversity that is primarily attributed to Müllerian mimicry. Previous research has identified the red-black mimetic color variation in Bombus melanopygus to be driven by genetic changes in a major upstream developmental gene (Hox gene Abd-B) dictating segmental morphology. Using a stage-specific transcriptomic approach, Rahman et al. unravel how this gene ultimately drives the melanic pigmentation differences, identifying a suite of genes from the most upstream Abd-B, to intermediate developmental genes, and finally to a set of interacting downstream melanin and redox genes.
