Hives generally consist of one to two deep boxes called hive bodies. The hive body serves as a brood chamber where the queen lays her eggs and the workers take care of the larvae. Above the hive body, the beekeeper places supers intended to store honey whose number depends on the amount of honey produced by the bees. Hive bodies and supers are equipped with wooden frames (generally ten per compartment) serving as supports for the combs. The rest of the hives consist of lids, grids, and trays which contribute to their stability, ventilation, protection, and compartmentalization.
