Honey bees are social insects that collect nectar and pollen to feed themselves and their developing larvae. They add enzymes to the nectar to begin the process of inverting the sugars to make honey. Inside the cells of the honey comb nectar is converted to honey. Water has to be evaporated from the honey as the process continues. Bees fan their wings to produce currents of warm air that assists evaporation. When the honey is almost ripe (around 20% moisture) the bees cap the cells with wax.
Autumn and Spring
When there is a dearth of nectar it is important to provide supplementary feed to honey bees.
Spring feeding is 1 part sugar to 2 parts water.
Fall feeding is 1 part sugar to 1 part water.
