There’s nothing more annoying than settling down to sleep and hearing the sound of a mosquito buzzing around you.
The only thought most of us ever give to this noise is “I need to get rid of this insect, immediately”, but it turns out that the mosquito is actually quite a(n)  31  creature.
A tern of scientists from Oxford University in he UK, in  32  with the Royal Veterinary College in London and Chiba University in Japan, recently published a study that found some interesting facts about the world’s most  33  insect.
By placing eight cameras inside a tiny film studio, the scientists could study several mosquitoes up close. The high-tech cameras filmed the insects at 1,000 frames per second, meaning the scientists were able to study the insects’  34  in never-before-seen detail. However, it wasn’t always straightforward. 
“Recording mosquitoes during free-flight represented a huge technical challenge due to their small size,  35  wing beat frequency, and the presence of large antennae and legs that can  36  the view of their wings,” Simon Walker of Oxford University, co-author of the study, wrote.
Published in the journal Nature, the study found that mosquitoes flap their wings around 800 times a second. As a  37  , house flies flap their wings about 200 times a second, and hummingbirds 50 times a second.
Richard Bomphrey of the Royal Veterinary College, the study’s leader, believes that mosquitoes have a unique flying method that sets them apart from other flying insects.
“We predicted that they must make use of clever tricks, as the wings  38  their direction at the end of each half-stroke.” he wrote in the study.
Hopefully, the discovery of the mosquito’s special abilities will be of benefit to engineers in the future. The findings could lead to better aircraft, or even improvement to tools like lenses or pumps.
But the scientists hope their study can one day be   39  to new developments in more human-focused use.
“The more we know about mosquitoes, the better our chance of understanding their flight behavior, how they carry disease and  40  how to stop them from doing so,” Walker wrote.
