Spider mite eggs are spherical and colorless when first deposited, but later become white as hatch approaches. Nymphs and adults are oval shaped and generally yellow or green in color. There are usually one or more dark spots on each side of their bodies.
Damage is expressed as stippling, and bronzing of the leaves and leaf veins.
Feeding is particularly damaging during the first 4 to 5 months following transplanting in fall. Mite densities of five per leaflet during this critical period of plant growth substantially reduce berry number and overall plantation yield. The highest mite populations are often observed following the peak spring fruit harvest, and this peak is typically followed by a rapid, natural decline in mite density. 20 mites per leaf later in the season. Predators play an important role in keeping twospotted spider mite populations in check.
