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]
Phasmatodea eggs resemble seeds in shape and size and have hard shells. They have a lid-like structure called an operculum at the anterior pole, from which the nymph emerges during hatching. The eggs vary in the length of time before they hatch which varies from 13 to more than 70 days, with the average around 20 to 30 days. [15]
The activity of the larvae will often leave an irregular discolored pattern on the leaf. Larvae will feed and pupate within the leaf, without needing to migrate to a fresh leaf. A fully grown larva is ~5.5 mm long, dorsoventrally flattened, and a dull pale yellow. The larval period lasts for 7–12 days, and is followed by pupation. [3]
A female leaf-footed bug, family Coreidae and tribe Acanthocephalini, deposits an egg before flying off. Coreidae is a large family of predominantly sap-sucking insects in the Hemipteran suborder Heteroptera. [1] The name "Coreidae" derives from the genus Coreus, which derives from the Ancient Greek κόρις (kóris) meaning bedbug. [2]
Adults feed on the adaxial side of tender paddy leaves and gradually roll the leaf lamina upward. Adult leaf rolls are partial and ephemeral. Then adult female oviposits clutches of up to 8 eggs within these rolled leaf lamina. The incubation period of female is about 4 to 7 days. After hatching, neonate grubs start to migrate to the leaf axil ...
Zelus renardii, commonly known as the leaf hopper assassin bug, [1] [2] is a predacious insect contained within tribe Harpactorini. [3] Diurnal and found on both wild and crop plants, Z. renardii has spread from its native habitats in western North and Central America into three other biogeographic regions across the globe.
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.
Its common name, "sawfly", derives from the saw-like ovipositor that is used for egg-laying, in which a female makes a slit in either a stem or plant leaf to deposit the eggs. [5] The first known use of this name was in 1773. [6] Sawflies are also known as "wood-wasps". [7]
