3. FIG. 2
Bacterial symbioses among insects. Phylogenetic relationships among the main bacterial symbionts of insects that have been analysed are shown. Species whose genomes have been completely sequenced appear in bold. Free-living relatives appear in grey. P, primary endosymbiont; S, secondary symbiont; F, free-living. *The species name is under the category Candidatus.
