Cotoneaster (Cotoneaster)-Spider mite

Includes twospotted spider mite (Tetranychus urticae)

Pest description and damage Several species of spider mites can cause damage in deciduous, evergreen and coniferous ornamentals. Appearance of these mites varies with the species, although all are 0.02 inches or smaller. Adults and nymphs can be yellowish, greenish, or reddish brown, depending on species. Twospotted mites are oval and yellowish-brown or green with distinctive black spots on the body. Mites damage leaves and fruit indirectly by feeding on leaves, which causes stippling, bronzing, and possibly leaf drop. The reduction in photosynthesis causes loss of vigor.
