Royal cradle: bespoke queen-cell wax shapes honeybee destiny
A Nature 2026 study shows queen cells are built from specially engineered wax that is chemically and physically distinct from worker wax: richer in unsaturated fatty acids, with lower density and strength but a higher melting temperature. A younger, dedicated crew of bees heats the wax to ~40°C to shape the royal nursery, altering its chemical signature. Grafting queen larvae into standard worker wax caused high mortality (62.5%), suggesting that wax properties, alongside royal jelly, influence queen development and that honeybees use a specialized queen-rearing process. Researchers say the findings may extend to other bee species as well.
