Eurycantha calcarata typically reproduce through sexual reproduction and produce eggs that hatch 4.5-6.5 months later. When no males are present in the population, this stick insect exhibits parthenogenesis instead. Eggs are typically 8.2 mm in length and 4 mm wide, with a somewhat cylindrical shape.
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]
An interesting character is that the eggs of Spinotectarchus acornutus are covered in short spines giving it a hairy appearance. This trait is also shared with Asteliaphasma, another genus of endemic stick insects. However, these stick insects can be distinguished by other traits such as the morphology of their genitalia. [1]
The Phasmatodea (also known as Phasmida or Phasmatoptera) are an order of insects whose members are variously known as stick insects, stick bugs, walkingsticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles , although this name is shared by both dragonflies and crane flies. [ 1 ]
The behaviour of this stick insect is highly unusual for an insect species, in that the males and females form a bond in some pairs. [4] The females lay eggs while hanging from branches. Hatching can happen up to nine months later. The nymphs are first bright green and active during the day, but as they mature, they turn black and become nocturnal.

The large eggs resemble plant seeds, and are well-camouflaged on the forest floor. [8] Eggs hatch in early spring, and nymphs resemble miniature adults. Like other stick insects, A. horridus is hemimetabolous, and nymphs grow by moulting, going through six instars until final adulthood. Argosarchus horridus eggs illustrated by Des Helmore
