Pest Mites

Spider mite (adult)
Identification tip: Spider mites range in color from yellow, to green, to black. During periods of active feeding twospotted mites and Pacific mites have dark spots. Often, however, the spots are barely visible or may coalesce to large dark areas, making it difficult to distinguish the two species.

Spider mite (eggs)
Identification tip: Eggs are minute, round, and translucent, with color ranging from a light tan to light yellow. They are laid on leaf surfaces.

Spider mite damage
Identification tip: Feeding by webspinning spider mites makes leaves appear "sanded" and worn.

Spider mite damage
Identification tip: Spider mite feeding causes the browning of walnut foliage.
