Extatosoma tiaratum, commonly known as the spiny leaf insect, the giant prickly stick insect, [2] Macleay's spectre, [3] or the Australian walking stick, is a large species of Australian stick insect. [4] [5] The species has the Phasmid Study Group number PSG9. [6]
Newly hatched Extatosoma tiaratum stick insects mimic these ants to avoid predation. [ 5 ] Workers of Leptomyrmex can be easily recognized by elongate antennal scapes which surpass the posterior margin of the head by more than one half their length, a medially notched hypostoma, mandibles with 7–15 teeth and 5–12 denticles, and a laterally ...
The phasmid Extatosoma tiaratum, resembling dried thorny leaves as an adult, hatches from the egg as a replica of a Leptomyrmex ant, with a red head and black body. The long end is curled to make the body shape appear ant-like, and the movement is erratic, while the adults move differently, if at all.

Some species, such as the young nymphs of Extatosoma tiaratum, have been observed to curl the abdomen upwards over the body and head to resemble ants or scorpions in an act of mimicry, another defense mechanism by which the insects avoid becoming prey.
Extatosoma [1] is a genus of phasmids, in the monotypic subfamily Extatosomatinae, with two species. One occurs in Australia , one in New Guinea . Both have a colour morph imitating leaves, and one imitating lichen.
E. tiaratum actively sways back and forth or side to side when disturbed or when there is a gust of wind, with a frequency distribution like foliage rustling in the wind. This behaviour may represent motion crypsis, preventing detection by predators, or motion masquerade, promoting misclassification (as something other than prey), or a ...
