Aceria ilicis causes felt-like galls (erinea), which are a patch of glandular hairs, caused by gall mites of the family Eriophyoidea. The bulge is 2–3 mm high on the upperside of the leaf of holm oak (also known as evergreen oak) and the depression below is several mm wide; there are usually several on a leaf.
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.
Aceria chondrillae [1] (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), [ 2 ] a highly competitive herbaceous perennial composite found in Europe, Asia, Australia and North America.

Eriophyes is a genus of mite that forms galls, mainly on the leaves of deciduous plants. Some are called blister mites. The blue butterfly Celastrina serotina has been reported to feed on these galls and also on the mites, making it one of the uncommon carnivorous Lepidoptera. [1] Whereas other mites have four paired legs, Eriophyes have only ...
Aceria mackiei, previously Eriophyes mackiei, the live oak erineum mite, is an abundant eriophyoid mite that produces leaf-blister galls on coast live oak, interior live oak, huckleberry oak, and canyon live oak. [1] This mite's ability to induce galls in oaks of both the black oak group and the intermediate oak group is unique. [1]
Eriophyes laevis is a gall mite which makes small, pimple-like galls on the leaves of alder (Alnus species). The mite was first described by the Austrian zoologist , Alfred Nalepa in 1889 and is found in Europe and North America.
