A strange species of bees have evolved to consume carrion, unlike other bees that prefer pollen. These species of bees called "vulture bees" have special gut microbes that aid in the digestion of meat. Entomologists collected and studied the guts and genetics of this insect.
Researchers led by experts from the University of California, Riverside found meat-eating bees in Costa Rica that evolved to eat carrion and avoid competition for nectar.
