Eriophyidae
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 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. Notable species Notable species in this family include: *'' Abacarus hystrix'', the cereal rust mite *'' Abacarus sacchari'', the sugarcane rust mite *'' Acalitus essigi'', the redberry mite, which affects blackberries *'' Aceria chondrillae'', the chondrilla g ...

Abacarus Hystrix
''Abacarus hystrix'', the cereal rust mite or grain rust mite, belongs to the family Eriophyidae. They are extremely small with adults measuring up to in length and only have four legs at the front of the body. Viewing by the human eye requires a 10 – 20X lens.Whalen, J. and Cissel, B. 2012. Cereal Rust Mite in Timothy. Available at: The adult mites are usually yellow but also have been seen to be white or orange. The cereal rust mite was first found on ''Elymus repens'' (couch grass), a very common perennial grass species. It has now been found on more than 60 grass species including oats, barley, wheat and ryegrass, found in Europe, North America, South Africa and Australia.Gibson, R. 1974.

Acalitus
''Acalitus'' is a genus of mites in the family Eriophyidae. These cosmopolitan, microscopic arthropods form galls on various plants, and some species such as '' Acalitus essigi'' and ''Acalitus vaccinii'' are pests of agricultural significance associated with berry crops. This genus includes, but is not limited to the following species: *'' Acalitus acanthus'' Smith-Meyer, 1990 *'' Acalitus accolus'' Flechtmann, Amrine & Stasny, 1995 *'' Acalitus acnistii'' (Keifer, 1953) *'' Acalitus aethiopicus'' Smith-Meyer, 1990 *'' Acalitus amicorum'' Flechtmann ''in'' Flechtmann, Kreiter, Etienne & Moraes, 2000 *'' Acalitus amydros'' Flechtmann & Etienne, 2001 *'' Acalitus ancyrivalis'' Smith-Meyer, 1990 *'' Acalitus anthonii'' Keifer, 1972 *'' Acalitus australis'' (Lamb, 1952) *'' Acalitus avicenniae'' (Lamb, 1952) *'' Acalitus batissimus'' Wilson, 1970 *'' Acalitus bosquieae'' (Farkas, 1961) *'' Acalitus brevitarsus'' (Fockeu, 1890) *'' Acalitus calycophthirus'' (Nalepa, 1891) *'' Acalitus ...

Alfred Nalepa
Alfred Nalepa (19 December 1856, in Werschetz – 11 December 1929, in Baden bei Wien) was an Austrian zoologist specializing in the field of acarology. He studied natural sciences at the University of Vienna, and from 1886 was associated with the ''Lehrerbildungsanstalt'' in Linz. In 1892 he returned to Vienna, where he was high school teacher of natural history at the ''Elisabethgymnasium''. He described many species in the field of acarology, and was the taxonomic authority of the gall mite family, Eriophyidae.

Aceria Guerreronis
''Aceria guerreronis'', the coconut mite, is an eriophyid mite which infests coconut plantations. It is economically devastating, and can destroy up to 60% of coconut production. The immature nuts are infested and injured by mites feeding in the portion covered by the perianth of the immature nut. Description The coconut mite is small, with a length of about and a width of ; this is too small to see with the naked eye. The mite is white and translucent, long and slender, with two pairs of legs. Populations build up rapidly, and the presence of this mite is generally indicated by the damage it does, and confirmed microscopically. Distribution ''Aceria guerreronis'' was first described by Hartford H Keifer in 1965 from Mexico, but it is unclear whether it originated from the Old or New World. The coconut palm originated in the South Pacific region and spread along the coasts of Asia, and later Africa. It was introduced into the Americas by traders in the sixteenth century, but ...

Aceria Fraxini Leaf Galls
''Aceria'' is a genus of mites belonging to the family Eriophyidae, the gall mites. These tiny animals are parasites of plants. Several species can cause blistering and galls, including erineum galls. A few are economically significant pests, while others are useful as agents of biological pest control of invasive plants such as rush skeletonweed (''Chondrilla juncea''), creeping thistle (''Cirsium arvense''), and field bindweed (''Convolvulus arvensis''). There are over 900 species in the genus. In 2017, a new species, '' Aceria pycnocomi'' was found on '' Pycnocomon rutifolium'' in Spain.

Aceria Chondrillae
''Aceria chondrillae'' (chondrilla gall mite, skeletonweed gall mite) is a gall-forming deuterogynous eriophyid mite. It is often used as a biological control of the noxious weed ''Chondrilla juncea'' (rush skeletonweed), a highly competitive herbaceous perennial composite found in Europe, Asia, Australia and North America.Krantz, G.W. and Ehrensing, D.T. (1990). ‘Deuterogyny in the Skeleton Weed Mite, Aceria Chondrillae (G. Can.) (Acari: Eriophyidae)’, International Journal of Acarology, Vol. 16, No 3, pp 129-133. Biological description At maturity, mites are yellowish orange in colour, with females ranging from 0.19-0.26 mm in length with the males slightly smaller at, 0.165-0.180 mm.Powell G.W., Sturko A., Wikeem B.M., Harris P.
