Subspecies
Habits
The subspecies T. n. viridinotata has one generation per year. It overwinters in the trunk of pear trees． Nymph and adult eat the leaves of Glochidion puberum. The eggs are laid in pear trees. The mottled colors and texture if T. n. novaehollandiae allow it to blend into the bark of the trees where it is usually found, motionless, with legs and antennae thrust out in front. Some spots of green on the tegmina are said to resemble moss on the bark.
When its thorax is pinched, T. n. novaehollandiae emits two large drops of a yellow fluid from openings on the dorsal surface of its protonum, as well as smaller amounts from other apertures on its body. The fluid is also produced by the tegmina when they are compressed.
