Worker Bees In 'Reproductive Class War' With Queen, New Research Discovers

ScienceDaily: "Bee colonies are well known for high levels of cooperation, but new research demonstrates a conflict for reproduction between worker bees and their queens, leading some workers to selfishly exploit the colony for their own needs. The study focused on Melipona scutellaris -- a Brazilian species of highly social stingless bees, found throughout the Atlantic rainforest. Colonies contain around 1,500 workers and are headed by one single-mated Queen."
