busy bee

Bee pic by PO GustafssonBetween 20 000 and 60 000 bees live in a single hive. The queen bee lays 1 500 eggs a day and lives for up to 2 years. The drone, whose only job it is to mate with the queen bee, has a lifespan of around 24 days - they have no stinger. Worker bees - all sterile females - usually work themselves to death within 40 days in summer, collecting pollen and nectar. Worker bees fly up to 14km (9 miles) to find pollen and nectar, flying at 24km/h (15 mph).

Pollen is the main supply of protein and vitamins for bees, with the 10 amino acids they require. Nectar is up to 80% sugar but less than 0.2% in protein, so nectar is the carbohydrate supply for the hive. Bees place the nectar in honeycomb cells and then evaporate the water from the nectar by rapid wing movement. When the amount of water is less than 18%, the mixture is called honey and the bees cap off the cells. Thus honey is 80% sugars and 20% water. A mixture of honey and pollen is called "bee bread" and is the food for larvae and bees.

A worker bee communicates her floral findings by performing a dance on the honeycomb. The orientation of her movements and the frequency of her vibrations indicate the direction and distance of the flowers.
