There are many species of russet mites: the tomato russet mite (Aculops lycopersici), the citrus russet mite (Phyllocoptruta oleivora), the hemp russet mite (Aculops cannibicola) and many others. Adults and nymphs may appear white, tan, pink or yellow and are almost invisible to the naked eye. Russet mites do not produce the webbing, thus may go unnoticed until there is a build-up of a large population as well as visible damage.
The damage usually presents itself at the bottom of the plant and moves upwards together with the mite population. Visible damage includes deformation and folding of the leaf blade, with a curling of the leaf edges. The leaves become russeted and bronzed, and gradually dry out.
There are specific natural enemies for different species of mites.
