(A) Results of a permutational analysis of variation (PERMANOVA) showing the effect of host species and location on gut bacterial composition (open referenced dominant bacterial community) across the three best-sampled dragonfly hosts (Orthetrum pruinosum, Orthetrum sabina, and Pantala flavescens). (B) Results of PERMANOVA showing the individual comparisons of 5 host species (Orthetrum pruinosum, Pantala flavescens, Trithemis aurora, Urothemis signata, and Zygonyx iris) based on their gut bacterial composition at a single geographic location—Shendurney.
