<i>Wolbachia</i> is a heritable alphaproteobacterial symbiont of arthropods and nematodes, famous for its repertoire of host manipulations, including cytoplasmic incompatibility. To be vertically transmitted, <i>Wolbachia</i> must efficiently colonize the female germ line, although somatic tissues outside the gonads are also infected. In <i>Drosophila</i> spp., <i>Wolbachia</i> is usually distributed systemically in multiple regions of the adult fly, but in some neotropical hosts, <i>Wolbachia</i>'s only somatic niches are cerebral bacteriocyte-like structures and the ovarian follicle cells. In their recent article, Strunov and colleagues (A. Strunov, K. Schmidt, M. Kapun, and W. J. Miller. mBio 13:e03863-21, 2022, compared the development of <i>Drosophila</i> spp. with systemic or restricted infections and demonstrated that the restricted pattern is determined in early embryogenesis by an apparently novel autophagic process, involving intimate interactions of <i>Wolbachia</i> with the endoplasmic reticulum. This work has implications not only for the evolution of neotropical <i>Drosophila</i> spp. but also for our understanding of how <i>Wolbachia</i> infections are controlled in other native or artificial hosts.
