These resilient jaws help honeybees shape and manipulate beeswax, a substance secreted from specialized glands on their abdomen. By gripping and pulling the beeswax with their mandibles, honeybees can mold it into hexagonal cells, creating the iconic honeycomb structure where they store honey, pollen, and raise their young.

3. Defense Mechanism:

Honeybees are highly organized social insects, and their mandibles play a crucial role in defending their colony against potential threats. When sensing danger, honeybees use their mandibles to bite and grip intruders, such as predators or competing insects. Though their stinger is typically their primary line of defense, the mandibles provide an additional layer of protection, allowing honeybees to immobilize and potentially injure adversaries.

4. Queen Rearing:

The intricacies of honeybee society include the remarkable process of queen rearing. The mandibles of worker honeybees are involved in selecting larvae destined to become queens. Worker bees carefully uncap cells containing young larvae and inspect them with their mandibles. Based on specific hormone levels and nutritional factors, worker bees determine which larvae have the potential to develop into future queens. This selection process showcases the adaptability and importance of honeybees’ mandibles in shaping the destiny of their colony.

Anatomy of Honeybee Mandibles
