A colony contains three kinds of bee doing three unrelated jobs, and almost every misreading of a hive comes from expecting one of them to behave like another.

Three kinds, one mother

All of them come from eggs laid by the same queen. A fertilized egg becomes a female, either a worker or a queen depending entirely on how she is fed. An unfertilized egg becomes a drone. That is the whole genetic story and everything else follows from diet and cell size.

The queen

One per colony, usually. She lays and she produces the pheromone that tells the colony it has a queen. She does not direct anything; a colony is not commanded, it is coordinated chemically.

She is longer than a worker with a tapered abdomen and she moves differently, purposefully across the comb while workers move around her. She takes about 16 days from egg to emergence, which is the number behind the two-week inspection interval.

The workers

All female, all sterile in a healthy colony, and they do everything. Their job changes with age rather than by assignment: cleaning cells first, then nursing brood, then building comb, then guarding, and finally foraging in the last weeks of life.

That progression is why a colony robbed of foragers recovers differently from one robbed of nurses, and why a swarm, which takes a spread of ages, functions immediately while a package takes weeks.

Workers can lay, and it is bad news when they do. In a colony queenless long enough, workers begin laying unfertilized eggs, so everything that emerges is a drone. Multiple eggs per cell and domed cappings across worker comb is the signature, and it is covered in a queenless colony.

The drones

Male, larger, blunt-bodied, and they have no sting. They do not forage, do not build and do not defend. Their only function is to mate with virgin queens from other colonies, which happens away from the hive and kills them.

A colony tolerates them through the season and evicts them before winter, which looks brutal and is simply arithmetic. Drones in fall are consumption with no return.

Why it matters when you open the hive

Drone brood in worker cells means a failing queen or laying workers.
Drones in large numbers in late fall suggests something is wrong.
Finding eggs matters more than finding the queen, because eggs prove she was there within three days.
A calm, busy colony with a good pattern is telling you all three castes are in the right proportion, which is most of what an inspection is checking.
