Cover Story: The European wasp spider, Argiope bruennichi, is an emerging arthropod model system, but its microbial community has never before been investigated in detail. Indeed, studies on the microbiota of spiders are just beginning to scratch the surface—with increasing evidence suggesting that spiders are an untapped source of novel commensal or (endo)symbiotic bacteria. In this study, Sheffer et al. discovered that A. bruennichi hosts a dominant, highly divergent bacterial symbiont of the Tenericutes phylum, which is present in every tissue type and is vertically transmitted from mother to offspring. The microbial community within A. bruennichi, beyond the dominant symbiont, varied significantly between individuals and populations, but not between tissue types. View this paper.
