The conspicuous adult female bug is dark, orange-red, about 8 mm long and produces a large, white, waxy, ribbed egg sac when mature. The tiny juveniles will crawl away and start feeding on the plant sap along the midribs of leaves. As they mature, they move back to the stems.
This sap sucking insect is a pest of perennial plants, favouring Vachelia and citrus trees. Like aphids and other scale insects, it produces honeydew that is colonised by sooty moulds.
