Fig. 5From: Prevalence and relationship of endosymbiotic Wolbachia in the butterfly genus ErebiaUnrooted phylogenetic relationship based on polymorphic SNPs for Wolbachia from 147 Erebia specimens (see Additional file 2: Table S2). Pie charts at each terminal node depict the frequency of Erebia host species carrying a given Wolbachia haplotype. Gray dots indicate nodes with > 95% bootstrap supportBack to article page
