One common, yet false assumption about bees is that that their buzzing
is caused by the beating of their wings. Not true. The sound is actually
the result of the bee vibrating their flight muscles. This is
especially pronounced in bumblebees,
as they must warm up their bodies considerably to get airborne at low
ambient temperatures. Yet, the sound they do produce while fearful
to many humans has indeed inspired a good number of musical compositions
over the years.
