Australian native stingless bees are similar to european honeybees in many ways, but they’re also very different, too.
This week I was lucky enough to attend a harvest and a hive split of these amazing social insects, in a inner-city backyard in Sydney…
Firstly, the honey harvest, from hive 1.
Tim Heard (Native Bee expert and possibly the friendliest scientist ever) cracks open a Tetragonula native bee hive with Michael Mobbs.
The top box of the hive is open. This is the ‘sugarbag’ section, where the bees store their honey and pollen.
The second box down has a semi-ceiling, which restricts the brood comb to the lower boxes.
This allows for occasional harvest of the sugarbag above, and also better facilitates splitting the hive, to increase the number of tetragonula colonies.
A good harvest from a healthy hive. Tim is happy.
The tetragonula bees are understandably agitated by their hive being temporarily opened, and tend to fly around at this point, getting in one’s eyes and nose…
Tim shows a pollen deposit, a conglomerate of thousands of flowers, collected from the city over the past 4 years…
Harvest time. Tim’s tool to break up the sugarbag, so the honey can be drained.
Flip the box over a tray, and out drains the honey.

A very happy Michael, with his first proper sugarbag honey harvest in 4 years…
The tetragonula honey is much more liquid than apis mellifera (european honeybee) honey… being about 70% water, as opposed to 15% for the normal honey you would buy or harvest.
A rare treat. It tasted sweet, and strange, and tangy. The memories of millions of flowers, all in a mouthful.
Tim also harvested some remnant sugarbag off the roof of the brood box – each ‘sugarbag’ is a small pot of honey or pollen filled resin, about the diameter of your thumbnail.
Next up, it was time to split one tetragonula hive into two.
This process involves splitting the brood chamber of a healthy hive, and creating two hives as a result.
One hive will retain the queen bee, and will carry on as before.
European honeybees rear their own new queen, when needed, from fertilised eggs by feeding royal jelly to certain baby bees. Not so with tetragonula, however.
The tetragonula bees are different – members of this new hive without a queen will actually go and get a new virgin queen, and escort her home to be lady of the manor, so to speak.
Tim splits the hive down the middle of the brood box.

The lower half of the brood chamber, showing tetragonula’s amazing spiral brood comb formation. The knife points out the brood comb, while around that part you can see more sugarbags of honey and pollen…
Above and below – the two halves of the brood chamber.
Tim Heard and his right hand man Tony prepare to place an empty second box on the newly split hive, for the brood comb to grow up into.

Strapping up time. The hive is now split, and will grow over the warmer months to be of a similar size to what it was previously.
The other half of the hive is in a similar box, on its way to a new backyard to increase pollination, diversity and species resilience.
