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.

GBIF citizen-science records
It is estimated from how often the Tegra novaehollandiae is recorded against all the insects logged in Hangzhou (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
