[1] Adult Banks grass mites range from green to brown in colour and are approximately 1/32 of an inch (~0.79 mm) in length.

[1] On either side of the body is a row of brown/reddish-brown spots, the number and position of which can be used to distinguish O. pratensis from the related two-spotted spider mite (Tetranychus urticae).

[1] This species can be distinguished from other Oligonychus by features such as the pattern of striation on the body, the setae on the legs and the shape of the male genitalia.

Their feeding creates chlorotic spots on leaves, with severe cases resulting in leaf dieback or fruit that are undersized or fail to form.

These include phytoseiid mites (Amblyseius scyphus, several species of Neoseiulus, Phytoseiulus persimilis), the spider Dictyna consulta, the predatory gall midge Feltiella macgregori, the convergent lady beetle Hippodamia convergens and the insidious flower bug Orius insidiosus.
