How beetle larvae thrive on carrion

The burying beetle Nicrophorus vespilloides buries the cadavers of small animals in soil to use them as a food source for its offspring. However, the carcass and thus the breeding site are highly susceptible to microbial decomposition and putrefaction. Researchers from the Max-Planck-Institute for Chemical Ecology, the University of Mainz and the University of Giessen, Germany, show that Nicrophorus vespilloides beetles are able to replace harmful microorganisms with their own beneficial gut symbionts, thus turning a carcass into a nursery with a microbial community that even promotes larval growth.
