Queen Bees: The Heart of a Honey Bee Colony
Queen bees lay the eggs that become the next generation of honey bees. Follow a queen from egg to adult, see how workers care for her, and learn what eggs and brood can tell a beekeeper about her colony.
ONE BEE, COLONY-WIDE INFLUENCE
What Do Queen Bees Do?
The queen is the colony’s primary reproductive female. At the height of the season, a healthy queen may lay around 2,000 eggs in a day. She lays fertilized eggs that grow into females and unfertilized eggs that grow into male drones.
She also produces pheromones that help maintain colony cohesion. Workers feed, groom, and surround her, distributing these chemical signals throughout the hive.
A queen does not command workers like a human leader. Colony decisions emerge from communication among thousands of bees, local conditions, food availability, and the colony’s needs.
FROM EGG TO ADULT
How Queen Bees Develop From Eggs to Adults
Queens and workers begin as fertilized eggs. Nurse bees feed a young female larva abundant royal jelly when raising a queen. She usually emerges about 16 days after the egg was laid. See Penn State Extension’s guide to queen development.
Egg
The queen lays a fertilized egg. In an emergency, workers can enlarge a cell around a young female larva.
Larva
Nurse bees feed the larva abundant royal jelly throughout development.
Pupa
The capped queen cell protects the developing pupa during transformation.
Adult
A virgin queen emerges, matures, and may take mating flights when conditions allow.
NATURAL COLONY CHANGE
Why Colonies Raise New Queen Bees
Swarming
A thriving colony may reproduce by dividing. The old queen leaves with part of the workforce while the original colony raises a successor.
Supersedure
Workers may replace an aging, injured, or poorly performing queen while the colony remains in place.
Emergency
If a queen is suddenly lost, workers can attempt to raise a replacement from a very young female larva.

How Beekeepers Check Whether Queen Bees Are Laying
Responsible beekeepers look beyond simply finding the queen. They inspect the brood pattern, eggs and young larvae, colony temperament, population balance, food stores, disease signs, and seasonal context.
- A consistent brood pattern appropriate for the season
- Eggs and larvae of different ages
- A population capable of caring for brood
- No unexplained queen cells or prolonged brood interruption
- Written records that reveal change over time
For example, note the date, which frames held eggs and whether open brood and capped brood were present. Compare that entry with the next visit. Finding eggs tells you a queen laid recently, even if you missed her during the inspection.
KNOW THE CASTES
How Queen Bees, Workers and Drones Differ
| Queen | Workers | Drones |
|---|---|---|
| Primary reproductive female | Female bees that perform most colony tasks | Male bees whose primary biological role is mating |
| Develops in a queen cell and receives sustained royal jelly | Develop in worker cells and shift tasks with age | Develop from unfertilized eggs in larger cells |
| Can live for several years, though performance changes | Life span varies greatly by season and workload | Often removed from colonies when resources decline |
RESPONSIBLE DECISIONS
When Beekeepers Introduce New Queen Bees
Confirm the Need
Investigate nutrition, mites, disease, weather, brood breaks, and other causes before blaming the queen.
Choose Appropriate Stock
Ask how the breeder’s colonies fare through local winters, how they behave during inspections, and what rules apply to moving bees into your area.
Monitor Introduction
Introduce a new queen carefully, minimize stress, and verify acceptance and egg laying afterward.

Common Questions About Queen Bees
Is there always one queen in a honey bee colony?
Most established colonies normally have one laying queen, although brief overlap can occur during replacement or swarming.
How can you identify a queen bee?
She usually has a longer abdomen, a smoother-looking thorax, and a circle of attending workers. Size and color vary, so behavior and body shape matter more than color alone.
Does the queen control every bee?
No. Her pheromones influence colony organization, but workers make many collective decisions through decentralized communication.
What is royal jelly?
Royal jelly is a nutrient-rich glandular secretion made by nurse bees. Sustained feeding helps a female larva develop into a queen.
Why do beekeepers mark queens?
A small, carefully applied paint mark can make a queen easier to locate and may indicate the year she emerged. Marking should be done without injuring her.
What should I do if I find a swarm?
Keep a safe distance and contact an experienced local beekeeper or swarm-removal network. Our guide to bee swarms explains what to report.
