Technical Abstract: This commentary provides background and an evaluation of a paper to be published in the Proceedings of the National Academy of Sciences in which social wasps were found to harbor significant populations of two species of the yeast genus Saccharomyces. Apparently, the yeasts were acquired during feeding and propagated in the intestinal tract of the wasps. The main habitats of Saccharomyces species in nature are unknown, but recent studies have suggested that they occur on the bark of hardwood trees, which is where the wasps feed. Conditions within the digestive tract of the wasps favor hybridization among the species and may be a major site for interspecific hybridization, which will lead to the development of new species of Saccharomyces.
