Reconstructing the phylogeny of Blattodea: robust support for interfamilial relationships and major clades

Abstract Cockroaches are among the most recognizable of all insects. In addition to their role as pests, they play a key ecological role as decomposers. Despite numerous studies of cockroach phylogeny in recent decades, relationships among most major lineages are yet to be resolved. Here we examine...
