The peacock mite's name suggests that their feather-like (or leaf-like) setae adorning their backs are evocative of a peacock's plumage. They also have long hair-like setae projecting from rear (caudal setae) that have been compared to a trailing peacock tail. The 5–7 pairs of caudal setae can be flicked over the body very quickly, so they are used like whips in defense against predators. They may also help in wind-borne dispersal.
They are classified in the superfamily Tetranychoidea, being its most ornate members.
