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.

Aceria anthocoptes is a 'free-living' eriophyid. Because of its life history and its morphology, this mite is considered to be a vagrant species.JOURNAL, Dragana Rancic, Branka Stevanovic, Radmila Petanović, Biljana Magud, Ivo Tosevski, André Gassmann, Anatomical injury induced by the eriophyid mite Aceria anthocoptes on the leaves of Cirsium arvense, Experimental and Applied Acarology, 38, 4, 243–253, 2006, 16612668, 10.1007/s10493-006-0013-3, This mite can be found in a number of European countries and in the United States. As of 2001, it is known to exist in 21 countries. It is the only species of eriophyid mite that has been found on Cirsium arvense throughout the world.

In the United States

This species is found in the following states:JOURNAL, L. Smith, E. de Lillo, J. W. Amrine, Jr., 2010, Effectiveness of eriophyid mites for biological control of weedy plants and challenges for future research, Experimental and Applied Acarology, 51, 1–3, 115–149, 10.1007/s10493-009-9299-2, 19760101, Also included in BOOK, Edward A. Ueckermann,weblink Eriophyoid Mites: Progress And Prognoses, 978-90-481-9561-9, 2010, {{div col|colwidth=13em}}

Behavior and life cycle

These mites produce multiple generations each year, and probably overwinter on root or the root buds.This mite normally spends the winter as fertilized female adults, remaining under bud scales of the thistle. They emerge in the spring. They continuously reproduce during times other than winter, creating a new generation every two to three weeks. Aceria anthocoptes mite feeds by sucking the contents of the leaf cells.

Use as a biological control agent

Aceria anthocoptes is considered to be a good potential biological control agent for Cirsium arvense, the Canada thistle. It damages both the epidermal cells and deeper mesophyll layers, on both the upper and lower surfaces of this invasive weed. The result is visible deformation and folding of the leaf blade, with a curling of the leaf edges. The leaves become russeted and bronzed, and gradually dry out.
