This mite lives only in humans and is of the genus follicle (genus Demodex). The exact name of the follicle is a sebaceous(Demodex folliculorum). Among the arthoropod class Chelicerata (Chelicerata, which include spiders, etc.), And is included in the very numerous order of mites (Acarina). Follicle fat causes substantially no clinically apparent disease, and indicates that it is infected over 10% of human population.
