Used for shipping a queen bee, this rectangular wooden container has three circular chambers covered in a wire mesh that hold the queen bee and a few accompanying workers bees, who feed her in transit. Two holes at the ends are sealed during transit, one with a cork and the other with a sugar-candy plug. When the cage is introduced to the hive, the bees work their way through the candy plug, and the queen is released.
