The eggsThe eggsIf the queen lays a fertilized egg, it gives birth to a worker 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 or a queen. By cons, a unfertilized egg will give birth to a
drone.drone.The egg is white, cylindrical, elongated and slightly The egg is white, cylindrical, elongated and slightly
curved. At the time of spawning, egg queen fixed at one curved. At the time of spawning, egg queen fixed at one end to the bottom of the cell. The egg seems to be end to the bottom of the cell. The egg seems to be
standing in the cell. Then for 3 days (on average), the egg standing in the cell. Then for 3 days (on average), the egg grows and eventually bowed to lie at the bottom of the grows and eventually bowed to lie at the bottom of the

Then a last chrysalis, muscles and organs are transformed. Then a last metamorphosis(slough) intervenes. It will be necessary a metamorphosis(slough) intervenes. It will be necessary a few hours so that the new cuticle dries. Then the image few hours so that the new cuticle dries. Then the image
