Remarks

• Structure: Adult female reddish-brown, occupying a deep pit in the twig it lives on (mostly in the axils), the mouth of the pit being covered with the mass of thick yellow wax, of irregularly globular shape, already formed by the second-stage female. The cavity burrowed out is frequently quite deep in the bark, and even seems sometimes to extend into the wool. The dimensions very: some of the waxy coverings are only about 1/15 inch, others reach 1/8 inch. The wax is very hard (Maskell, 1891).
• Economic Importance: Regarded as the most important species, among the honeydew secreting Hompterans, for apiculture in New Zealand, (Walton, 1979; Crozier, 1981; Gaze & Clout, 1983; Airborne Honey, New Zealand, 2003). The annual yield of honeydew honey at Canterbury plains foothill forest (South Island, New Zealand) was estimated at 3302 tones (Walton, 1979).
