Veins Rs, M, and Cu1a straight, more or less parallel to each other; head and pronotum yellowish.
Range
Native to Australia; in our area, California (introduced) (1)

Life Cycle
Adults are mainly found on leaves and new apical shoots; females lay their eggs on the newly growing leaf axils. The nymphs develop on the young shoots, secreting copious amounts of honeydew; excessive feeding may result in leaf curling. There are multiple generations per year (2)

First recorded from California in 1991. While common, it is not considered to be as injurious to its hosts as other Eucalyptus psyllids established in the state (3)
