Brood Development Timeline
Explore the development stages of queen, worker, and drone bees from egg to adult
Visualize honey bee brood development from egg to adult. Queens emerge in 16 days, workers in 21, and drones in 24 — split across four stages: egg, larva, pupa, and adult. Pick a starting date to project capping and emergence days for inspection planning.

- How long does it take for a honey bee to develop?
- Queens emerge after 16 days, workers after 21 days, and drones after 24 days. All three pass through four stages — egg (3 days), larva, pupa, and adult — but the larval and pupal stages differ in length by caste.
- When are worker bee cells capped?
- Worker brood cells are capped on day 9, when the larva spins its cocoon and enters the pupal stage. Worker bees emerge on day 21.
- When are queen cells capped and when do queens emerge?
- Queen cells are capped on day 8 and virgin queens emerge on day 16 from the egg being laid. Queens develop fastest because they are fed royal jelly throughout the larval stage.
- How long do drones take to emerge?
- Drones take 24 days from egg to emergence — the longest of any caste. Drone cells are capped around day 10.
Queen vs Worker
The only difference between a queen and a worker is diet. Larvae fed exclusively royal jelly develop into queens — completing development in just 16 days compared to 21 for workers.
Drone development
Drones take the longest to develop (24 days) and come from unfertilised eggs. They have no father but do have a grandfather!
The egg stage
All three castes share the same 3-day egg stage. The queen lays each egg vertically in the cell; it gradually tilts over before hatching.
Capping timing
Workers cap queen cells on day 8, worker cells on day 9, and drone cells on day 10. Spotting capped cells helps identify what's developing inside.
