A viral picture authentically exhibits a Demodex mite that lives on human faces.
Whereas the scanning electron micrograph is real and unaltered, it exhibits the top of a silkworm moth caterpillar and never a Demodex mite, as posts on social media misleadingly claimed.
In June 2024, posts in multiple Fb teams claimed to indicate a picture of a microscopic creature recognized as a Demodex mite, a tiny arthropod that lives, mates, and lays eggs on human facial pores and skin.
The wording of the practically similar posts first appeared in a post made in a Neil deGrasse Tyson fan group on Might 30, 2023. As of this writing, that unique submit had obtained round 1,500 feedback and round 2,900 shares. The picture accompanied by the identical caption has additionally appeared on different social media websites together with X, Instagram, and LinkedIn.

However the viral posts had been incorrect. Reverse-image searches on TinEye and Google Images led us to the inventory picture company Alamy, which licenses the unique picture and identifies it as a coloured scanning electron micrograph of the top of a silkworm moth caterpillar.
To confirm this identification, Snopes reached out to entomologists Kyle Koch, an educator and diagnostician on the College of Nebraska–Lincoln, and Lynn Kimsey, an emeritus professor of entomology on the College of California, Davis. Each Koch and Kimsey confirmed by way of e mail that the creature within the picture is a caterpillar and never a Demodex mite.
For these causes, we have now rated the declare as “Miscaptioned,” which means that it’s a real, unaltered picture that has been accompanied by a deceptive caption.
Though the viral picture doesn’t depict one, the Demodex genus of mites are very actual. Two species within the genus, Demodex folliculorum and Demodex brevis, do stay on human faces and are collectively known as facial mites. In line with a paper revealed within the scientific journal Dermatology Experiences in 2022, mites of each species are frequent human parasites that, in accordance with some research, have been discovered on the pores and skin of as much as 100% of adults and 70% of youngsters.
To the untrained eye, the lumpy our bodies and stubby legs of Demodex mites, that are arthropods, and silkworm moth caterpillars, that are bugs, share some similarities. Essentially the most obtrusive distinction between the animals is their dimension: whereas grownup Demodex mites attain a most size of round 0.4 millimeters, silkworm moth caterpillars measure round 2 millimeters simply after hatching and develop to a most size of round 75 millimeters earlier than they construct cocoons and start the method of pupation into an grownup silkworm moth, in accordance with the Encyclopedia Britannica.
This distinction in scale, nonetheless, is just not instantly apparent when coping with a close-up picture just like the one in query.
For entomologists like Koch, different options of the specimen that seems within the viral picture make it straightforward to find out that the animal is just not a mite from the Demodex genus even when dimension can’t be taken into consideration.
One characteristic that stood out to Koch was the morphology of the specimen’s mouth, which he defined doesn’t resemble the needle-like chelicerae or beak-like rostrum discovered throughout the various Demodex species. One other clue was the hairlike bristles seen all around the creature within the viral photographs. Identified to entomologists as setae, these bristles are by no means discovered on Demodex mites, that are as a substitute lined in tiny, semi-transparent scales.
An actual Demodex mite might be seen crawling up a human eyelash within the video beneath, which the biotechnology firm BioTissue posted to YouTube in 2014.
Data from reverse-image searches exhibits that the picture from the viral posts has circulated on social media websites since at the least 2014, when a Reddit person posted it to the r/WTF subreddit. Notably, this 2014 submit appropriately recognized the creature as a silkworm.
The Demodex misidentification seems to have emerged in June 2018, when X person @AntonioParis posted the picture with a caption studying, “An alien from one other world? It is a microscopic picture of Demodex. These mites stay in your face.” Comparable posts sharing the misidentified picture quickly appeared in posts on Reddit, Facebook, and different social media websites, and have periodically circulated ever since.
