What term is used to describe the glue-like substance bees use to seal their hives?

The term used to describe the glue-like substance that bees use to seal their hives is propolis. Propolis is a resinous mixture that honeybees collect from various plant sources, including buds and bark. Bees use propolis to fill gaps and cracks in the hive, providing insulation, protection against pathogens, and creating a more stable environment for the colony.

It has antimicrobial properties, which helps to maintain hive hygiene and can protect the bee colony from diseases. The use of propolis demonstrates the bees’ instinctual behavior to create and maintain a safe, healthy living space for their community.

Other substances such as honey, cera (wax), and pollen serve different purposes. Honey is primarily a food source for bees, cera is the wax used to build honeycomb, and pollen is collected as a protein source for developing larvae. Each of these components has its own critical role within the hive, distinct from the sealing function of propolis.
