Maximum amount of honey is consumed by brood, especially in spring and summer. In that time the queen lies daily from 1500 to 2500 eggs. After three days, when the larva hatches from the egg, bees start to feed it very intensively. During next five days it grows 1 500 times larger than its original size. Bees need for the brood approximately from 10 to 15 kg of honey per month in that time. The next part of honey supply is converted to wax and some of honey is also utilised by adult bees.
