the buzzing of the bees (chance operations)

the gentle sound of bees buzzing among the flowers

a favorite sound of summer,  

but why do bees buzz?  

and how do they make that buzzing sound?  

of course, we can't get into the minds of bees!  

but by observing their behaviors

we can make a few guesses;  

i look into this subject

using some of my favorite books about bees

as it is a question

i have been asked whilst giving my talks;  

i found that theories and ideas had changed over time

no surprise there

history shows we form ideas about a thing

only to learn more

and change our minds later;  

firstly, buzzing is of course, commonly heard

when bees are simply flying

during which time, the wings are vibrating very fast,  

but bees will also buzz at other times

and the tone of the buzzing may alter.  

one example is

they seem to buzz more aggressively

if their nests are disturbed

or if they are disrupted during foraging;  

they will also buzz more aggressively

if attacked or  

defending themselves from predators

or during conflict with other members of the colony

as the queen bee;  

of course, bees buzz from flower to flower

but whilst foraging, for a few seconds

they tend to remain quiet;  

not so during buzz pollination

the anthers of some flowers, i.e., the parts carrying the pollen

only release their pollen if they are shaken,  

bumblebees achieve this

by placing the upper part of their body, thorax

close to the anthers

then vibrating their flight muscles very fast;  

at the same time, they make a lovely buzzing sound

buzz pollination is especially beneficial for tomatoes

and other fruits

resulting in a more abundant crops;  

one particular type of high-pitched buzzing sound

made by honey bees is called 'piping',  

piping occurs directly prior to swarming

but can also occur during the disturbance of a hive;  

there are differing views

about which bees in the honey bee colony

initiate the piping prior to swarming;  

sometimes, the queen starts buzzing first state

then the piping begins

with a small group of experienced forager bees

called 'nest-site scouts'

who produce a "piping-signal"

that primes the workers for swarming;  

again, when honey bees 'waggle dance'

to communicate the locations of food

flowers upon which to forage

to other members of the colony,  

it is not only the movements of the honey bee,  

but also the buzzing sounds made,  

that convey the whereabouts of the forage sources;  

also the noise may cause by air passing

over the edge of a membrane

in tiny holes in the segments of the abdomen,  

(these holes are called spiracles) :  

anyway, the wings are involved making buzzing

the buzzing sound made by bumblebees  

which is at least greatly amplified

by the vibration of the wing membranes.
