''Aceria anthocoptes'', also known as the russet mite, rust mite, thistle mite or the Canada thistle mite, is a species of mite that belongs to the family Eriophyidae. It was first described by Alfred Nalepa in 1892. ''Aceria anthocoptes'' can be found on ''Cirsium arvense'', the Canada thistle, and is a good potential biological pest control agent of this invasive weed.

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 appointed professor 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.
