Bumble bees have a queen that produces drones, workers and other queens.
However, the colonies are annual, unlike the honey bee's year-round colonies. Queens emerge from their winter resting stage, called diapause, each spring and begin foraging for nectar and pollen. Bumble bees hold pollen on their hind legs like the honey bee. The queen uses the collected pollen and nectar to rear workers. Worker bees are non-reproductive females.
