Phylogenetic relationships among mayflies are poorly known and current classifications do not appear to closely reflect phylogeny. DNA sequence data were collected for a wide range of mayfly taxa representing every major lineage. These data were used to estimate phylogenetic relationships at the familial level and to illuminate the phylogenetic position of Ephemeroptera relative to other insect orders. The monophyly of Paleoptera (Odonata + Ephemeroptera) and the currently recognized mayfly suborders will be discussed in light of these additional data.
