1 The life of the bees in the hives egg larvea chrisalis The bees Adult

2 This is the life cycle page. A bee is like a butterfly because it goes though several stages in its life. Keep reading to find out about a bee’s life.

3 The eggs If the queen lays a fertilized egg, it gives birth to a worker or a queen. By cons, a unfertilized egg will give birth to a drone. The egg is white, cylindrical, elongated and slightly curved. At the time of spawning, egg queen fixed at one end to the bottom of the cell. The egg seems to be standing in the cell. Then for 3 days (on average), the egg grows and eventually bowed to lie at the bottom of the cell. After 3 days, the egg hatches by dissolving the membrane. It then becomes a larva. An egg is between 1.3 and 1.8 mm long, 0.5 mm wide and weighs between 0.12 and 0.22 mg. Development time, size and weight are the basis of race, lineage, and even climatic conditions.

4 the larvae The larva has the form of a small worm, consisting almost exclusively of a digestive tract As the larva increases(grows), it was moved on 5 occasions. She(it) wins a great deal of weight: 900 times for the worker, either 140 mg in the operculation 1700 times for the queen, or 250 mg in the operculation 2300 times for the male, or 346 mg in the operculation The worker grows from 2,7 to 17 mm and the queen of 4,2 in 16,5mm. In the 9th day, the alveolus is operculée by a small wax cork. The last days of the embryonic stage(stadium) are dedicated to the construction of a cocoon. The duration of the embryonic stage(stadium) varies according to the caste: queen, worker or drone.

5 The chrysalis The pupal stage(stadium) is the last stage(stadium) with that of the trained(formed adult or imago. At this stage(stadium), the head, the eyes, the antennas, the oral rooms(parts,plays), the thorax, the legs and the belly have the characteristics of those of the adult. The cuticle becomes more and more darkened; his(her,its) color is used to determine the age of a chrysalis. Inside the chrysalis, muscles and organs are transformed. Then a last metamorphosis(slough) intervenes. It will be necessary a few hours so that the new cuticle dries. Then the image drills the opercule of wax with its mandibles. After his(her) exit(release) of the alveolus, the adult spreads(displays) his(her) wings and his(her) antennas, lets dry his(her) hairs and then begins his(her) activities. The imago Hardly born, the bee is still soft and will be needed from 12 to 24 hours so that the cuticle

6 The imago Hardly born, the bee is still soft and will be needed from 12 to 24 hours so that the outside cuticle dries. As long as the exosquelette around vulnérantes glands is not hardened, the young bee cannot prick(fall). In 8 in 10 days following the birth, the internal development (in particular glands) continues. The queens and the drones pursue as for them the development of their reproductive organs. In the emergence, the middleweight is of: mg for the worker 196 in 225 mg for the drone 178 in 292 mg for the queen

7 The developemen of a worker bee It is necessary 21 days so that an egg of bee is transformed into worker: 3 days: stage(stadium) of the egg 10 days: embryonic stage(stadium) 8 days: stage(stadium) of nymph During the first 8 days, the egg is visible at the bottom of the cell(unit). From the 9th day, the cell(unit) is operculée (closed) by the workers further to the production of a specific pheromone by the larva. During her development, the worker in future is fed only during 3 days in the royal jelly.
