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]
Occasionally, the eggs are also laid on the top side of leaves. The eggs are minute, covered in a dark substance, and laid singly. Each female lays a total of between 18 and 101 eggs in their lifetime, with an average of 55. The incubation period is about four days. [3]
Both adults and nymphs of the spiny shieldbugs are predatory, feeding on the larvae of other insects, especially on leaf bugs, beetles, aphids and caterpillars. The choice of the prey depend on the season and availability of food. However both adults and nymphs also suck sap from plants. The female lays eggs on tree trunks and leaves.
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.
Adult female lays eggs singly or in cluster of 21 to 52 eggs on both surfaces of leaf, or sometimes on the dead aphid body. Eggs are yellowish, and oval shaped. With the development, the eggs turned to black and later become completely black before hatching. The length of eggs are about 1.25 to 1.37 mm. The incubation period varied from 3 to 4 ...
In the wild, females lay eggs from summer through to autumn, with eggs hatching in a period of 11–24 months. [16] The body of female goliath stick insects becomes very large during the egg-laying period. [2] When eggs are laid, the female will ‘flick’ the egg outwards to the ground using her abdomen, this aids in egg dispersal.
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]
