Where is the brood located?

Brood is located in boxes below the queen excluder. Most of the brood is located in the center of the box and decreases towards the ends of the box.


Egg laying




Queen lays one egg in the middle of each honeycomb cell. The young queen bee may at first start laying two or three eggs in one cell, but this is quickly normalized.

She stops laying eggs only during the winter.



Open and capped brood

The brood in cells that are capped with wax is called sealed (capped) brood. Those are cells with pupae.

The brood in the cells that are open (not closed with wax) is called open brood. Those are cells with eggs and larvae.


Queen, worker bee and drone development

Worker bees and queens develop from fertilized eggs.

All larvae are fed with royal jelly for the first three days. If the larva continues to be fed with the royal jelly until the end of its development, the queen will develop (only from fertilized eggs). Otherwise, the worker bee will develop.

Drones develop from unfertilized eggs.


Number of days required for the development of the queen, worker bee and drone in the stage of egg, larva, and pupa:

Egg Larva Pupa Total
Queen 3 5,5 7,5 16
Worker Bee 3 6 12 21
Drone 3 6,5 14,5 24

After three days an egg becomes a larva.


On the first day the eggs are vertical, and after that they are in a horizontal position. So if you see the eggs in an upright position - these are the new eggs that were laid that day.


Bees intensively feed the larva for a certain number of days and then close the cell with a thin layer of wax. When the cell is capped, the larva makes a cocoon and becomes a pupa. After a few days, a young fully formed bee comes out of the cell.

The number of days required for development varies depending on whether it is a worker bee, a drone or a queen.

Queen bee develops fast and needs 16 days to come out of the cell.



The difference between worker bees and drone brood, and queen cells

Drone brood has wider cells than a regular brood (worker bees brood). When it's capped, the worker bee brood is flat while the drone brood is slightly rounded.

Cells from which queens will develop are queen cells. Queen cells are easily distinguished from other brood cells. Those cells are full of royal jelly and very elongated.

Queen cells

Each bee leaves its cocoon in the cell, so the cell size decreases over time. In order to ensure the normal development of new bees, you need to periodically replace the old and darkened honeycomb with the new one.
