Bumblebee Vibration

In physics waves explain how energy is propagated or transmitted. Vibrations are the physical evidence of waves/particles. Waves and vibrations are everywhere in Nature. Vibration is a patterned or random change over a period of time and the wave is a length traveled during the vibration period.

Something that is vibrating may shake at the same time. … This vibration will send sound waves to the ear and to the brain. I would add that vibrations are also experienced directly through the body, and that bodies may actually pick up signals that the brains (in humans) routinely miss. Indigenous peoples have intuitively understood that every living thing has its own wave/vibration – which to me is like a kind of signal or signature that says,“ I am a bumblebee or a pear tree” or in this case “I am a bumblebee that needs pollen so I shake my body”.

Intuition and sensing are non – rational, experiential ways of knowing not much valued in a culture like ours.

Scientists have discovered that wild bumblebees are born with the ability to remove pollen from nectarless flowers using high-frequency vibrations.

The study, published in the Journal of Insect Behavior, is the first to show that the ability to vibrate flowers to extract pollen is an innate behavior in Bumblebees and one that is refined over time and gives a rare insight into the complexity of the pollination services provided by these creatures.

The research was carried out by evolutionary biologist Dr Mario Vallejo-Marin of the Faculty of Natural Sciences, along with other colleagues.

Vallejo-Marin states: “We studied captive bumblebees from their very first exposure to flowers that need to be vibrated to extract pollen and found the creatures instinctively and almost immediately begin vibrating their bodies.

We also found that over time and with practice, bees are able to tune down their vibrations, removing pollen while potentially saving energy. Initially bees tend to vibrate on the flower petals, but after two or three visits they focus their efforts exclusively on the part of the flower where pollen is produced. Bumblebees learn to reduce the frequency of the vibration they are using during pollen extraction as they gain more experience manipulating flowers that require vibrations to release pollen.

This shows the extensive capacity of these insects to learn complex motor skills to maximize their rewards from each flower they come into contact with.”

Although bumblebees’ ability to learn how best to collect nectar is well documented, this study is the first to show how vibrations change while foraging for pollen. The study also “proves” (westerners must have documented proof) that the buzz bees produce during flight and during pollen collection have clearly distinct acoustic signals.

20,000 species of plants including major crops, such as tomatoes and potatoes, rely on vibrating bees for pollination services. Apparently only some bees use vibration to collect pollen.

The study concludes that it is only by learning how bees pollinate that we can understand the consequences of declining bee populations. I find it fascinating that scientists are catching up to the Indigenous understanding that each creature uses its body vibration to ‘communicate’; bees use it to communicate with the flower in order to gather its pollen, but the above scientific conclusion seems simplistic to me because it neglects to mention what we already know, namely that pesticides are killing all insects including bees at an alarming rate.
