After a Taiwanese woman came in for treatment of a swollen eye, doctors were shocked to find four tiny bees living under her left eyelid, CNN reports.
The insects, known as sweat bees, are 3 to 4 millimeters (0.12-0.16 inches) in length, according to CNN affiliate CTS.
At a news conference, Hung Chi-ting, the head of the ophthalmology department at Taiwan's Fooyin University Hospital, told reporters, "I saw something that looked like insect legs, so I pulled them out under a microscope slowly, and one at a time without damaging things inside."
Sweat bees, also known as halictidae, "nest near graves and in fallen trees, so it's easy to come across them while hiking in mountains," Hung explained.
The woman, identified by her family name of He, said she thinks the insects blew into her eye while she was visiting a relative's grave site with her family. She tried to wash her eyes with water but she was still in severe pain.
"Tears wouldn't stop coming out of my eye," she said. "I was scared to death."
After three hours of agony, He finally visited the hospital, where doctors determined she was suffering from severe corneal erosion caused by the sweat bees.
