Tetranychus urticae (common names include red spider mite and two-spotted spider mite) is a species of plant-feeding mite generally considered to be a pest. It is the most widely known member of the family Tetranychidae or spider mites. Its genome was fully sequenced in 2011, and was the first genome sequence from any chelicerate.
Spider mites are members of the family Tetranychidae, which includes about 1,200 species. [1] They are part of the subclass Acari (mites). Spider mites generally live on the undersides of leaves of plants, where they may spin protective silk webs, and can cause damage by puncturing the plant cells to feed. [2]
Tetranychus is a genus of spider mite. Tetranychus is one of the most economically important genera of mites, due to its high potential to destroy agriculture. [ 1 ] It contains 159 described species, the most significant of which is Tetranychus urticae .
Well-known examples of prostigmatan plant parasites are species of the gall mites (Eriophyidae, e.g. the redberry mite Acalitus essigi), Tarsonemidae (e.g. the cyclamen mite, Steneotarsonemus pallidus), and the spider mites of the Tetranychidae (e.g. the two-spotted spider mite, Tetranychus urticae).

A study of another species, the spider mite Tetranychus urticae, showed that the red color was caused by carotene, which was beneficial for their hibernation. [4] T. grandissimum, belonging to the same order as spider mites, spend an extensive period of time in hibernation under the soil.
Ceratopogonidae is a family of flies commonly known as no-see-ums, or biting midges, generally 1–3 millimetres (1 ⁄ 16 – 1 ⁄ 8 in) in length. The family includes more than 5,000 species, [2] distributed worldwide, apart from the Antarctic and the Arctic.
