The peacock mites of the genus Tuckerella (the only genus of the mite family Tuckerellidae) are a significant herbivorous pest in the tropics, for example on citrus fruit. Other species dwell in grasses, possibly as root feeders.
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, and they are used like whips as a defense mechanism against predators. They may also help in wind-borne dispersal.
They are classified in the superfamily Tetranychoidea, being its most ornate members.
