About

Demodex is a microscopic mite that feasts on the hair follicles of mammals, including humans. Online, the animal periodically goes viral when an artistic rendering of the mite is shared on social media, making people horrified to learn that tiny mites live on their faces and feed on their eyelashes. Additionally, the Demodex has been the subject of numerous memes and other reaction-type content on social media.

Origin

Demodex was discovered by German scientist Gustav Simon in 1842 and named "Demodex" in 1843 by Sir Richard Owen.^[1] Roughly half of humans carry demodex and the mites are more likely to appear in older people. They may cause minor skin conditions in people.
