A bee's future as queen or worker may rest with parasitic fly
Strange things are happening in the lowland tropical forests of Panama and Costa Rica. A tiny parasitic fly is affecting the social behavior of a nocturnal bee, helping to determine which individuals become queens and which become workers. The finding by researchers from the University of Was...Why do some queen bees eat their worker bee's eggs?
Worker bees, wasps, and ants are often considered neuter. But in many species they are females with ovaries, who although unable to mate, can lay unfertilized eggs which turn into males if reared. For some species, such as bumble bees, this is the source of many of the males in the species. But in ...Disease threat may change how frogs mate
