Kenaikan Titik Didih
Worker bees go on flights to collect nectar and pollen to be turned into honey — an important staple to the honey bee diet.
Foraging for resources
Pollination happens when bees are hopping from flower to flower, collecting and sprinkling pollen as they go.

pollination?
Maintaining
the Hive
Honey bees collect water to keep their hive cool, insulate honeycombs, and even use it to re-hydrate any honey that has crystallized.
Swarming to
a New Home
When a hive becomes overcrowded, it’s time for the queen bee to leave with half of the colony in search of
a new home.
What is
a swarm?
A swarm is a cluster of traveling honey bees. They stay close together, with the queen bee protected in the center, while a scout bee is sent from the swarm to lead the search for a new home.
Honey bees communicate amongst each other in a special way: they dance. The “waggle dance” is how bees give each other directions to where the best flowers are.
