Very small (0.2 mm) mites, which have a translucent whitish or brownish body surface, depending upon the species (Picture 1). They suck on the cell layers of various plants and prefer young, growing shoots.
Ornamental plants. The mites are very small and remain well-hidden, normally found on the underside of leaves. High relative humidity favors reproduction and the spreading of these mites. The damage is frequently patchy.
