They feed on several fruit trees, vines, berries, veggies and decorative crops.

Samples of suspect mites are welcomed and can be submitted in man or woman or posted to our South Perth Business office.

Through feeding, they penetrate the leaf by inserting their chelicerae (stylet-like mouthparts) into the parenchyma cells of leaves and suck the cell contents into their overall body by a ‘pharyngeal pump’. This effects in discolouration of leaf tissue, where typical indications incorporate yellow places on the upper side of the leaf owing to chlorophyll depletion.
