Mites

Damage

Spider mites feed on the underside of the leaves, and can be found on older leaves as well as near the shoot tips. Lightly infested leaves become speckled; heavily infested leaves become bronzed and covered with webbing. Spider mites are a sporadic pest in blueberries and are rarely seen in most fields. Mite populations build up during the heat of summer, and can be more prevalent in hot dry locations. Mites can reside on weeds within blueberry fields.

Pest

Two-Spotted Spotted spider mites are yellowish-greenish with two dark spots on the back. They vary in size from near microscopic to clearly visible. These mites overwinter as orange females in the soil near the plant.
