“That innocent question hit me like a lightning bolt." Scientist's two-year-old son inspires discovery of new type of worker honeybee

Key Points:

• Researchers have discovered a new type of worker honeybee, termed "royal engineers," that specialize in building and maintaining queen cells by heating their thoraxes to soften and manipulate wax.
• Queen cells are structurally unique, made from wax that is less dense, more pliable, and has a higher melting point compared to worker cell wax, creating a specialized microenvironment essential for queen development.
• Experiments showed that queen larvae raised in cells made from worker wax were smaller and had higher mortality, indicating that the physical properties of queen cells significantly influence the growth and survival of future queens.
• This discovery challenges the previous assumption that queen development depended solely on royal jelly consumption, highlighting the complex architectural and biological strategies honeybees use to sustain their colony hierarchy.
• The findings reveal a higher level of organization and sophistication in honeybee society than previously understood, showcasing their intricate social and environmental engineering capabilities.
