Umbonichiton bullatus Henderson & Hodgson
Umbonichiton bullatus. Young adult female.
Knobbly scale — Umbonichiton bullatus Henderson & Hodgson
The species name bullatus means "knobbly or knobbed", because not only is the wax test knobbly but also the female's skin underneath has rows of rounded folds.
Biology: one or two generations per year. The new generation is produced from summer to autumn [the photo above was taken in May]. Probably overwinters as young adult females. Males and females develop on the stems, occasionally a few males also on the leaves.
Found on the stems of:
| Kunzea ericoides | kānuka |
| Leptospermum scoparium | mānuka |
| Podocarpus totara | tōtara |
| Weinmannia racemosa | kāmahi |
