Parsimony networks for endosymbiont ribotypes 1–32: A. Colored pie-slices indicate the proportion of ribotypes assigned to: (A) sample periods; and (B) host species (unidentified hosts excluded). Sizes of the pies scaled to reflect ribotype frequencies. Connecting lines indicate a single mutational step. Empty dots indicate inferred ribotypes that were not sampled in this study.
