Key Distinguishing Feature

Summer adult females are a yellowish-green, with 2 pronounced dark spots, one on either side of the body. In males these spots are less conspicuous. Both sexes possess 2 reddish eyespots. Over winter females stop feeding, egg-laying and become orange-red. The adult female is about 0.5mm long, oval-shaped and rounded at the rear. The colour can vary from orange, light and dark green, reddish brown and black. Adults damage plant foliage by piercing the cells and sucking the contents, causing chlorotic spots that give the leaf a stippled appearance.

Two-spotted mites, also known as two-spotted spider mites are found worldwide including throughout Australia. They have an extremely wide host range and are readily spread by wind. Under optimum conditions the life cycle of the two-spotted mite may be as short at 2 weeks and all stages may be found at the one time.
