Ask a random person to picture a bee, and they’ll likely conjure up the familiar black-and-yellow striped creature buzzing from flower to flower collecting pollen to bring back to the hive. But a more unusual group of bees can be found “slicing chunks of meat from carcasses in tropical rainforests,” according to the authors of a new paper published in the journal mBio. As a result, these bees have gut microbiomes that are markedly different from their fellow buzzers, with populations more common to carrion-loving hyenas and vultures. So they are commonly known as “vulture bees” (or “carrion bees”).

According to the authors—entomologists who hail from the University of California, Riverside (UCR), the University of Massachusetts, Amherst, Columbia University, and the American Museum of Natural History—most bees are essentially “wasps that switched to a vegetarian lifestyle.” But there are two recorded examples of bumblebees feeding on carrion dating back to 1758 and 1837, and some species are known to occasionally feed on carrion in addition to foraging for nectar …read more
