How a Bee Becomes Queen

Honey bees have a harsh caste system. Of the tens of thousands of bees found in a hive just about all of them are female workers and they do pretty much everything from cleaning and building the hive, to collecting pollen and nectar.

Their lives are so intense that while a worker can live from four to nine months during the winter, a worker bee born in the busy summer season will only last about six weeks before dying of exhaustion. It’s not a whole lot better for the 300 to 3000 male drones who basically hang around waiting to mate with the Queen during the summer after which they die or are kicked out of the hive and when fall comes, and they are of no more use. Then there’s that Queen. Like the bee, there are other names that mean queen.

There’s one per hive and she can live to be up to five years old laying up to 2,000 eggs in a day. And she owes her entire existence to a bitter protein-rich secretion called royal jelly. Given their long life and unique position, there’s rarely a need for a new queen, but when one dies or leaves the hive along with a swarm, the colony needs to find a replacement and fast.

In both situations, a larval bee is chosen to become the new queen. The science of how and why this happens isn’t entirely settled but one thing is certain, royal jelly plays a large role. Worker bees produce royal jelly from England in their heads called the hypopharynx and feed it to newly hatched honeybee larva.

The milky-yellowish substance is made of digested pollen and either honey or nectar. Not only is a high in protein but royal jelly also has a combination of vitamins especially vitamin B plus lipids, sugars, hormones, minerals including potassium, magnesium, calcium, and iron. This bee “super-food” also contains acetylcholine a neurotransmitter also found in humans. It’s what nerves use to tell muscles to start or stop moving and may also contribute to learning.

All those nutrients might explain why royal jelly is often marketed as an expensive, dietary supplement cure-all even though studies haven’t been able to prove that it does anything too significant for humans. We are after all, not bees. But for bees, it does a lot and around day three of the royal jelly diet is where things get interesting. Worker bees will choose a few of the larvae and continue to feed them royal jelly while every other larva is switched to a less nutrient intensive diet of honey pollen and water.

As the future queens gorge the royal jelly triggers other phases of development that workers don’t experience like the formation of ovaries for laying eggs. If one Queen emerges first she will search for and destroy any other Queens still developing in their wax cells and if multiple Queenscome out simultaneously they will fight to the death until only one Queen remains. We don’t know exactly how the worker bees decide which larvae get the royal treatment but for a long time, we thought it was random.

That would make sense because basically worker bees and queen bees are genetically identical. But there’s some evidence that the selection of a queen might not actually be so random. A 2011 study found that the larvae of future Queens have higher levels of proteins that increase some metabolic activities, so there may indeed be a tiny genetic difference in the two that plays a huge role.

Scientists are also still trying to figure out what it is about the royal jelly that lets it change a larva’s whole life. For a while, we thought it might be a hormone in the jelly or the way it affected insulin signals in the larvae then another 2011 study zeroed in on a protein called ROYALACTIN which when isolated and combined with other nutrients can transform larvae into queens just like royal juicy jelly.

Once they emerge Queens continue eating royal jelly their entire lives and given that the Queen lives a lot longer than the thousands of relatives around her, it sounds like a reasonable dietary choice for a royal bee to make.
