Demodex folliculorum is a species of face mite. D. folliculorum is one of the parasitic/commensal face mites that occur on people (other than Demodex brevis). Demodex derives from the Greek roots, demos- fat, and dex- worm. When large numbers of D. folliculorum are found on humans, the infestation is known as "demodicosis".
