Microbiome composition and function often change throughout a host's life cycle, reflecting shifts in the ecological niche of host. The mechanisms that establish these relationships are therefore important dimensions host ecology evolution; yet, their nature remains poorly understood. Here, we sought to investigate microbial communities associated with complex cycle dung beetle Onthophagus taurus relative contributions stage, sex, environment determining microbiome assembly. We find O. plays diverse microbiota undergo drastic community development, influenced by environmental microbiota, and, lesser degree, sex. Contrary predictions, found egg pupal stages-despite absence digestive tract or defined microbe-storing organs-do not constrain maintenance, while host-constructed environments, such as maternally derived fecal pellet chamber constructed late larvae, may still serve complementary refugia for select taxa. Lastly, identify small putative core likely shape development fitness. Our results provide insights into employed solitary organisms assemble, maintain, adjust beneficial confront life-stage-specific needs challenges. As influence symbionts on ecology, evolution, has become more apparent so importance understanding how hosts facilitate reliable maintenance interactions symbionts.
