The layout and function of a bee colony's brood nest, often referred to as the "rainbow" pattern due to its visual structure.
1. Upper Row (Honey): The top of the frame is typically filled with honey. This stored honey serves as food for the bees during times when nectar is scarce, such as during a nectar dearth or the winter months. The honey acts as an energy source for the colony, ensuring survival when external food sources are limited.
2. Second Row (Pollen & Bee Bread): Directly below the honey, you'll find pollen and bee bread. Pollen is the primary protein source for adult bees, while bee bread (which is fermented pollen) is the main food for developing larvae. Bee bread is rich in both proteins and fats, which are essential for brood development. The bees collect pollen and store it here to support brood rearing.
3. Center (Queen’s Brood): In the central portion of the brood nest, the queen lays her eggs. This is where the brood (eggs, larvae, and pupae) develops. The queen's brood is crucial for the colony's growth, as these eggs eventually hatch into workers, drones, and new queens.
4. Edges (Drone Brood): On the outer edges of the brood nest, you'll find drone brood. Drones are male bees, and they are generally placed on the cooler edges of the frame because the development of drone larvae requires a slightly lower temperature than worker brood. The drone brood is not as densely packed as the worker brood and is usually on the outer parts of the comb.
This pattern, often described as a "rainbow," is a reflection of how bees organize their resources and brood to optimize colony survival and growth. The structure also helps regulate temperature, ensuring the queen's brood is nurtured in the optimal conditions for development.
