Bayesian phylogenetic tree based on sequencing of the mtDNA COI gene for 463 Belonocnema treatae sampled from 23 populations. Branch colors represent geographic separation between populations from West (light blue; populations 1–8) and East (orange; populations 10–23) and population 9 (grey). The outside bar represents the host plant affiliation for each collection site (red = Q. fusiformis, green = Q. geminata and blue = Q. virginiana). The different dots represent the infection status of each single individual with white = uninfected, yellow = wTre1, blue = wTre2, red = wTre3, grey = wTre4. Individuals with two or three dots indicate infection by more than one Wolbachia strain
