No buzz except for one bee!
For the first time in 99years there was a total eclipse that spanned coast to coast in the USA in August 2017.
Dr Cadence Galen and colleagues from the University of Missouri, had setup microphones along the projected route of the Eclipse from Oregon to Missouri. These were carefully setup amongst flowers to record the sound of the bees
during the progress of the eclipse. They decided it was sufficient to record for a period of three minutes.
The monitoring stations recorded a drop-off of the sound of flying bees as the eclipse progressed until at the point of total darkness,
the buzz of flying bees stopped, this totality lasted for 40 to 160 seconds, dependent on the location of the monitoring station .
Apparently this was true across all the monitoring points except for
one oddity when the sound of a solo bee flying around was recorded!
It was presumed that as the period of darkness accelerated, that those bees close to their hive returned as they would at night, but those that were foraging well away
from the hive, did as bees do during periods of inclement weather or rapid nightfall the sheltered in and under flowers.
Dr Galens comment was “Wherever they were except for one bee, for the period
of totality, they certainly weren’t flying!”

BEES TO BE REPLACED BY ROBOT POLLINATORS ?
From The Sun Newspaper
"BEE-BOT CROP AID"
The Sun reported that robotic bees could be used to pollinate many crops due the worldwide losses in bee colonies.
Three-quarters of crops rely on insects for pollination and so Scientists at Havard University in the USA have developed remote control "RoboBees" which are smaller than a paper-clip.
of the new style "bee" said these could be available for use within about five years. These little robots will be fitted with GPS trackers and a single bee could accept a command such as "Go to these 10 flowers" while the rest of their robotic pals could receive
another similar instruction.
This may get the crops pollinated, but could it lead to a reduction in pesticide controls?
happen to the price of honey as it becomes rarer?
Many questions come to mind.

DID YOU KNOW BEES SAY "WHOOPS",
WHEN THEY BUMP INTO EACH OTHER?
Interestingly this article was stimulated by a recent question on the “Q.I.” programme on t.v. (click on underlined words to jump to the actual article)
Researchers used to think that the “Whoops” sound was made as a ‘stop/’ signal only but recently researchers have found that honeybees do actually produce a “whoop” sound
when they bump into each other, the noise might just be conveying surprise as we might say “Oops!” they make a sound that goes “Whoops!” Not too dissimilar is it?. Bees produce the sound with their wing muscles to create the vibrational
pulse. One of the research team, Physicist Martin Bencsik from Nottingham Trent University in the UK. said,
"We have found that this signal is remarkably common, much more than previously
It's well known that honeybees communicate through vibrational signals, but why the bees actually make
them has been up for debate. Way back in the 1950’s, scientists suggested
that the vibration signal was used as a request for food, as they observed that
the noise was often followed by the bees exchanging meals. Later, researchers also noticed that the noise was used to inhibit another bee from performing
a waggle dance – a form of communication used to tell other bees where to go to forage. The stopping of this waggle dance
suggest that it worked as a 'stop signal' for some reason better known to the bee
But new research suggests
that the way the bees were investigated in those past studies was flawed, and the signal is more common than we thought.
"Scientists in the past have explored this signal in
artificial circumstances where they ensured that the bees under investigation would be trying to inhibit other bees," said Bencsik.
He also went on to explain, “In our latest research studies,
we have not manipulated our bees in any way, and this has revealed totally unexpected results, yielding new interpretations but also yet more mystery around this brief honeybee vibrational pulse." The team placed accelerometers into
the centre of two hives in the UK and in France to record bee noises that are inaudible to the human ear. The vibrations were recorded for a year,
and computer software scanned the recordings for the vibration "whooping" noise. He goes on to say "We believe that in only a small number of instances
is it used as an inhibitory signal and
therefore have proposed a new name – the 'whooping' signal."
The team found that the accelerometer would pick up six or seven "whoops" a minute, and from a very small area in the honeycomb. "There's no way a bee was trying to inhibit another one that frequently, and there's no way a bee would request food that frequently," Bencsik
told Sam Wong at New Scientist.
When the researchers also placed cameras inside the hive, they noticed that it happened most when the bees bumped into each other, but it also happened if the hive was knocked or shaken. "We suggest that, in the majority of instances, it is bees
being startled that produce the signal," says
Bencsik. In other words the bees are doing the bee equivalent of a surprised gasp – and it makes these adorable noises even better!
But the researchers aren't done yet – the team is now investigating if stressed colonies whoop more than unstressed colonies. "It shows promise that our methods can be used as a sensitive way of monitoring and assessing colony status for these
hugely important pollinators," said one of the researchers, Michael Ramsey.
What's next ? Technology & pollenation!
Researchers are now looking at Black
Mirror - style bee drones to replace the real thing, supposedly to help the current ack of bee population.

We certainly don't want to lose those cute "whoops"
if robot drones become the norm.
