I will give an overview of a few examples from our work on the microbiota of several insects, and rice. I will then describe the red flour beetle in more detail: its microbiome is beneficial for the host, but both the benefit and the microbial community structure vary dramatically. Across a 3-year period, the total load and composition of the bacterial community of laboratory stock populations fluctuated dramatically, cycling between a few dominant taxa and hundreds of rare taxa. Manipulative experiments suggest that this ecological drift is caused by changes in host population size and structure driven by laboratory maintenance protocols, as well as intrinsic differences in life stage-specific host-microbe interactions driven by host ecology. I suggest that such unstable microbial communities can serve as great model systems to understand the evolution and ecology of diverse host-microbial interactions.
