If you see pale bees — almost white, moving slowly, not aggressive — inside your klanceng colony, that's not a sign of disease. That's a newly hatched bee. And its presence means one thing: your queen is actively laying.
How Klanceng Prepares a New Cell
The process starts long before the queen arrives.
Nurse bees build a new cell from cerumen — a mixture of wax and resin. Once the cell is ready, they fill it completely: a blend of honey, pollen, and secretions from glands in their own heads. This is the baby's food. Everything is prepared before the egg exists.
Where does the food come from? It's already in the colony — honey collected by foragers over previous days, stored in separate honey pots. Pollen stored separately. Nurse bees draw from those reserves, mix them with their own glandular secretions, and regurgitate the mixture into the cell. Not raw nectar — material that has already been processed collectively by many bees over days.
One by one, bee by bee, until the cell is full. This is called mass provisioning — and it's different from Apis honeybees, which feed larvae a little at a time, day by day. Klanceng provides everything upfront, before the egg even exists.
Only after the cell is full does the queen arrive. She inspects it with her antennae, then places one egg on top of the food surface. One cell, one egg. The workers seal it immediately.
From that moment on, there's nothing inside but one egg on top of a full cell of food. No bee yet. What comes next takes almost 38 days.
What Happens Inside the Sealed Cell
The egg hatches into a larva within 6–7 days. The larva eats everything inside the cell — completely, leaving nothing. No one feeds it from outside; everything was already provided at the start.
After about two weeks as a larva, it stops eating and enters the pupa phase. This is where the transformation happens — from a small white larva to a fully-formed bee with wings, legs, and antennae. The process takes around 19 days.
Total: approximately 38 days from egg to adult bee ready to emerge.

Why Newly Hatched Klanceng Bees Are White
Because their exoskeleton hasn't hardened yet.
When a bee first emerges, its exoskeleton is still soft, still damp, and has no pigment. The characteristic black colour of klanceng develops through a process called sclerotization — and this takes days, not hours.
During this period, the young bee can't fly and can't forage. It stays inside the nest, starting with light duties: cleaning empty cells, caring for younger brood. This phase is called callow — a fully-formed bee that isn't yet ready for the outside world.
Apis honeybees also have a callow phase, but it lasts hours, not days. They harden and darken very quickly. That's why you almost never see white bees in a regular honeybee colony — they're solid before they become visible. In klanceng, the process is slower — because it doesn't need to be fast. Inside a nest guarded by thousands of workers, the young bee is safe. While its exoskeleton is still soft, it automatically stays inside, doing care duties. Once it hardens, it's ready for the risks outside.
This isn't a weakness. It's design. Staying inside while soft is what protects it.
If You See Many White Bees
That's a good sign. Your colony is growing.
The connection to food supply is direct: when a large tree nearby is flowering, foragers bring in more pollen. Within 24 hours, the colony starts building more cells. The queen lays more eggs. And about 38 days later, you'll see a wave of new white bees.
The white bees you see today are evidence of the food that came in several weeks ago.
