Specialized Honeybee Workers: Architects of the Queen’s Wax Abode

In an intriguing finding reported by scientists, a particular group of worker honeybees has been identified as being uniquely adapted to construct the waxy home for their queen within the hive. Worker bees are known for their diverse roles, ranging from food collection to nurturing young bees and caring for the queen, whose role is to lay all the eggs.

Recent research highlights that the honeybees tasked with building the queen’s quarters elevate their body temperature to effectively melt and blend specific chemicals into the wax. According to Julia Bowsher, a bee researcher at North Dakota State University who was not involved in the study, the discovery of a specialized group of bees dedicated to building queen cells is unprecedented.

No one had ever thought that there might be a specialized group of workers that were building these queen cells, Bowsher said.

The bees identified in this role are younger and exhibit distinct gene expression patterns that equip them for the task. Their work results in peanut-shaped chambers made from softer wax with a higher melting point compared to the wax used for worker bee homes.

Queen bees are typically nourished with royal jelly produced by the glands of worker bees. While diet has historically been considered crucial to developing a monarch, this new study, published in the journal Nature, indicates that the queen’s environment also influences their development. To explore this theory, researchers raised queen larvae in containers capped with either queen wax or worker wax. Despite consuming royal jelly, queens raised in worker wax were smaller and had lower survival rates.

For centuries, we believed ‘you are what you eat’ was the only rule for making a queen bee. Our study rewrites that rule to say ‘you are where you live, too, said Kai Wang, a study co-author from the Chinese Academy of Agricultural Sciences.

The findings provide a unique view inside the hive, yet many questions remain unanswered. Honeybees play a crucial role in pollinating and supporting the growth of crops such as blueberries, squash, watermelon, and almonds. Further research is needed to uncover more about the secretive life of queen cell-building bees and the precise factors that contribute to the development of the hive’s leader.

Julia Bowsher expressed interest in further studies, saying, I would really like to know more about the specific chemical composition of this wax and which active ingredients are directly affecting the growth of the queens.
