Phylogenetic relationships among the dipteran species used in this study. Calyptrate flies are thought to represent a monophyletic group but the relationships among acalyptrate flies are not well understood [37-41]. There is support for a close relationship between Drosophila and the Calyptratae within a paraphyletic Acalyptratae [38-40].
