A mother from Buckinghamshire has told how she was terrified when she spotted an eight-inch dragonfly buzzing around her living room - like a "mini helicopter".
Rowena Wilkinson, 53, found the dragonfly after hearing her 24-year-old daughter's horrified screams coming from the front room.
According to ITV News, she said: "It sounded like a mini helicopter - it was that noisy.
"It was like a Jurassic monster. I didn't know whether to take a photograph or run but I managed to get close enough to take a few pictures.
"We waited for it to stop a bit and then I had to put my arm through the venetian blinds to open the window so it could get out."
Dragonflies have existed on Earth for 325 million years. Britain's longest dragonfly is the female of the golden-ringed species.
According to the Daily Mail, dragonflies have been threatened by widespread insecticide use, but are enjoying a resurgence thanks to conservation work and warmer weather.
