Honeybees release what are called pheromones, which humans also have. Pheromones are excreted through the glands of a honeybee. Pheromones have a smell that the other bees need to be aware of, because different smells mean different situations. During an emergency, a honeybee will use their wings to fan around a banana smelling pheromone to alert the other honeybees what is happening. The queen uses her pheromones to let the other honeybees know that she is their queen, and the hive she is in is their hive too. When the queen is ready to pass away or is getting old, she releases less pheromones, or different smelling ones, and that let's the other honeybees know that they need to prepare for a new queen soon.
The honeybees use their wings to control the temperature in their hive. When it needs to be warmed up for colder climates, honeybees will ball up together and fan their wings to generate a nice, toasty heat for themselves. In hot climates, honeybees will bring droplets of water to their hive, and fan those out to evaporate the cool sensation of the water. Without their wings, honeybees would freeze in the winter, or overheat in the summer.
Honeybees use their wings to create honey! When nectar is brought back to the hive from floral sources, a honeybee will put that nectar in a cell of the honeycomb, and she will then use her wings to fan the nectar, so it draws water out and becomes thicker. This is needed, so that the water content is down to at least 18%, and the honey will then not spoil.
With all the different uses of a honeybee's wings, they sure are buzz-y bees!
