Ω
mite An order of small Arachnida with rounded bodies. Mites are very abundant in the soil, feeding on plant material and invertebrate animals. Some parasitic mites (e.g. red spider) damage crops and can be serious pests. Others cause diseases in animals. Ticks are blood-suckers, some being vectors of diseases such as Rocky Mountain spotted fever in humans and fowls, and louping ill in cattle and sheep.\n(Source: ALL)
