Cheyletidae is a family of mites in the Trombidiformes. Some members are associated with parasitism in birds and mammals, for example causing Cheyletiellosis, also called "walking dandruff". Others are free-ranging predators in soil, forest litter, under tree bark and on foliage, in nests of a diverse range of animals, and in house dust. [more]
Eriophyidae is a family of more than 200 genera of mites, which live as plant parasites, commonly causing galls or other damage to the plant tissues and hence known as gall mites. About 3,600 species have been described, but this is probably less than 10% of the actual number existing in this poorly-researched family. They are tiny, microscopic mites and are yellow to pinkish white to purplish in color. The mites are worm like, and have only two pairs of legs. Their primary method of population spread is by wind. They affect a wide range of plants, and several are major pest species causing substantial economic damage to crops. Some species, however, are used as biological agents to control weeds and invasive plant species. [more]

Tenuipalpidae
Tenuipalpidae, also called "flat mites" or "false spider mites", are a family of mites, closely related to the Tetranychidae. They are reddish, slow moving, and normally feed near the midrib or veins on the underside of leaves. Several species, among them Raoiella indica, are important crop pests. Other common species include the Brevipalpus species , B. californicus, B. obovatus, and B. lewisi. [more]
Tetranychidae
Spider mites are members of the Acari (mite) family Tetranychidae, which includes about 1,200 species. They generally live on the under sides of leaves of plants, where they may spin protective silk webs, and they can cause damage by puncturing the plant cells to feed. Spider mites are known to feed on several hundred species of plant. [more]
