Bryobia is a genus of mites in the spider mite family Tetranychidae. The taxonomy of the genus is difficult. The genus has been revised several times. It is difficult to distinguish these tiny species from each other on the basis of morphological characters and there is little agreement on which characteristics are of importance. Also species can be variable in morphology. Over 130 species have been described but many of the names are likely synonyms.
