Roadmap To The Phylogeny Of Insects

The remainder of this book concerns itself with the major groups of insects, with accounts of their relationships, biology, and evolution. We have attempted to outline the relationships among the Recent and extinct insect orders as we believe are best supported by current morphological, molecular, and paleontological evidence. Figure 4.24 is a phylogeny of orders and the principal superordinal groups employed throughout this volume, with the classification summarized in Table 4.1.
