This animal, which is not really an insect but a mite, is frequently found on the leaves of roses as well as other plants. It is not larger than a pin head, yellowish or reddish in color, and sucks the vitality from the plant, causing the leaves gradually to turn pale and become stunted, and in time the plant dies, unless treatment is applied. These pests are particularly sensitive to sulphur, however, and flowers of sulphur dusted over the plant, as much as possible placed on the under side of the leaves, or mixed with water at the rate of an ounce of the sulphur to a gallon of water, and sprayed onto the plants, is usually a fairly satisfactory treatment. In some cases the use of soapsuds instead of the water to add the sulphur to, seems to be more efficacious.
