Umbonichiton adelus Henderson & Hodgson

Umbonichiton adelus. Young adult female.
Obscure tōtara scale
The species name adelus means "unseen, obscure", because this little scale is well hidden at the base of tōtara leaves, where the petiole twists a 1/4 turn from the stem.
Biology: not much is known about the life cycle, probably one generation a year.
Found on the underside of leaves of:
Podocarpus totara | tōtara |
