According to Moran and Telang 1998, "No study has yet produced evidence contradicting the hypothesis of parallel phylogenesis for bacteriocyte-associated endosymbiosis in insects." We have found evidence for multiple switches in associations between dryophthorine weevils and their bacterial endosymbionts using phylogenies derived from Bayesian and parsimony-based analyses.
