A Taiwanese woman who suffered what she believed to be a sudden and severe eye infection discovered she was unwittingly hosting four bees.

The insects had flown into her eye and were living beneath her eyelid and feeding on the fluid from her tear ducts.The 29-year-old woman, identified only by her surname, He, was treated for unbearable eye pain at Fooyin University Hospital last week.

Doctors treating her were surprised to find four bees beneath her swollen eyelid, and removed them in what has been described as a “world first”.

The hospital’s head of ophthalmology, Dr Hung Chi-ting, told CTS News at a press conference: “I saw something that looked like insect legs, so I pulled them out under a microscope slowly, and one at a time without damaging their bodies.”

Ms He said she had been pulling out weeds while tending a relative’s grave when she felt something fly into her eye.

The mysterious core seems to be the cause of features on its surface that have fascinated scientists since they were spotted by Nasa's New Horizons mission. "Before New Horizons, everyone thought Pluto was going to be a netball - completely flat, almost no diversity," said Tanguy Bertrand, an astrophysicist and planetary scientist at NASA's Ames Research Center and the lead author on the new study. "But it's completely different. It has a lot of different landscapes and we are trying to understand what's going on there."

The highly social birds will also remember that person if they come near their nests again, according to researchers from the University of Exeter. In the study, a person unknown to the wild jackdaws approached their nest. At the same time scientists played a recording of a warning call (threatening) or “contact calls” (non-threatening). The next time jackdaws saw this same person, the birds that had previously heard the warning call were defensive and returned to their nests more than twice as quickly on average.

She first believed it to be soil or grit, and rinsed her eye with water. However, the pain only grew worse, and by evening her eye was badly swollen and streaming with tears.

Four ‘sweat bees’ were found wriggling around beneath 29-year-old Ms He’s eyelid (CTB)

Dr Hung had first suspected inflammation of the cornea, but upon closer inspection under a microscope saw the insects’ wriggling legs.

The diminutive insects, known as “sweat bees” due to their predilection for human perspiration, were miraculously pulled from Ms He’s eyes alive.

The doctor said it was fortunate Ms He had not rubbed her eyes as it could have squashed and killed the bees, and this would likely have led to more serious injury and could have caused blindness.
