List of files and visuals associated with this text.


This family of microscopic mites includes a large number of tree and shrub pests. Homeowners rarely identify the causal organism because these mites are too small to see with the naked eye (less than 0.5 mm). Diagnoses are usually based on the damage symptoms, which are often distinctive. The most common types of damage are leaf spindle galls, leaf bladder galls and leaf erineum patches. A few other species may cause rusting symptoms or distorted leaves or buds.
