Frontal head images of all tested Drosophila species and their associated phylogeny. a Frontal view of the head of all 62 species, illustrating the diversity in overall size, as well as in the variance of the visual and olfactory sensory systems across this genus. Also worth noting is the disparity in pigmentation that extends across the whole head, including the antenna and the compound eye. b Phylogeny of 59 species of Drosophila where genetic material was available for use in this study (D. montium and two subspecies of D. mojavensis are missing). Species were selected to span the width of subgroups and represent the genetic diversity within this genus of insect. Some species are denoted with gray boxes to provide more visual separation between subgroups. (Data are provided at https://doi.org/10.17617/3.1D)
