Monteithiella Humeralis
''Monteithiella humeralis'', commonly known as the pittosporum shield bug is a species of herbivorous shield bug native to Australia and introduced in New Zealand. As its common name suggests, it is most commonly observed feeding on '' Pittosporum'' plants. Description ''Monteithiella humeralis'' adults are 9mm long with predominantly brown bodies and pale green legs. First instar nymphs are small and black, with circular bodies and white spots on the upper surface of the abdomen. Later nymph stages are similar to the first but with orange spots instead of white. Life history Adult females lay blue eggs on the underside of leaves which turn white after 2–3 days, and hatch after 5 days. Nymphs progress through 5 instars or juvenile stages before reaching adulthood. It takes around 41 days after eggs are laid for bugs to mature to adulthood. In New Zealand, adults are most abundant in November and March. while eggs and nymphs can be found from November to April. Ecology ...

Shield Bug
The Pentatomoidea are a superfamily of insects in the Heteroptera suborder of the Hemiptera order. As Hemiptera, they share a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families (16 extant and 5 extinct). Among these are the stink bugs and shield bugs, jewel bugs, giant shield bugs, and burrower bugs. Description The Pentatomoidea are characterised by a well-developed scutellum (the hardened extension of the thorax over the abdomen). It can be triangular to semielliptical in shape. The antennae typically have five segments. The tarsi usually have two or three segments. Shield bugs have prothoracic glands (in their thoraces, between the first and second pair of legs) that produce a foul-smelling liquid, which is used defensively to deter potential predators and is sometimes released when the bugs are handled. These prothoracic glands are also present in the nymphs, which are similar to adults except smalle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pittosporum
''Pittosporum'' ( or ) is a genus of about 200 species of flowering plants in the family Pittosporaceae. The genus is probably Gondwanan in origin; its present range extends from Australasia, Oceania, eastern Asia and some parts of Africa. '' Citriobatus'' can be included here, but might be a distinct (though closely related) genus. They are commonly known as pittosporums or, more ambiguously, cheesewoods. The species are trees and shrubs growing to 2–30 m tall. The leaves are spirally arranged or whorled, simple, with an entire or waved (rarely lobed) margin. The flowers are produced singly or in umbels or corymbs, each flower with five sepals and five petals; they are often sweetly scented. The fruit is a woody seed capsule, which bursts on ripening to release the numerous seeds. The seeds are coated with a sticky resinous substance. The genus is named after their sticky seeds, from the Greek meaning "pitch-seed". Tarata (''P. eugenioides'') and kohuhu (''P. tenuifolium'' ...

Nymph (biology)
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species). In addition, while a nymph moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. This is the case, for example, in Orthoptera (crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, whiteflies, aphids, leafhoppers, froghoppers, treehoppers etc.), mayflies, termites, cockroaches, mantises, stoneflies and Odonata (dragonflies and damselflies). Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera, are also called naiads, an Ancient Greek name for mythological water nymphs. Usage of the term 'naiad' is no longer popular among entomologists, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coprosma
''Coprosma'' is a genus of flowering plants in the family Rubiaceae. It is found in New Zealand, Hawaiian Islands, Borneo, Java, New Guinea, islands of the Pacific Ocean to Australia and the Juan Fernández Islands. Description The name ''Coprosma'' means "smelling like dung" and refers to the smell (methanethiol) given out by the crushed leaves of a few species. Many species are small shrubs with tiny evergreen leaves, but a few are small trees and have much larger leaves. The flowers have insignificant petals and are wind-pollinated, with long anthers and stigmas. Most species are dioecious, but some (particularly those native to New Zealand) species can sometimes have individuals with perfect flowers. Natural hybrids are common. The fruit is a non-poisonous juicy berry, most often bright orange (but can be dark red or even light blue), containing two small seeds. The orange fruit of the larger species were eaten by Māori children, and are also popular with birds. It is said t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trissolcus Basalis
''Trissolcus basalis'', or the green vegetable bug egg parasitoid, is a parasitoid wasp in the family Platygastridae known primarily for parasitising the horticultural pest '' Nezara viridula'', the green vegetable bug. Description Like other species of ''Trissolcus'', ''T. basalis'' is small (around 2mm long), mostly black in colour, and females have clubbed antennae. ''Trissolcus basalis'' can be separated from other nearctic ''Trissolcus'' species by the presence of coriaceous microsculpture on the mesoscutellum, pustulate setal bases, shallowly impressed episternal foveae on the mesopleuron, and an incomplete netrion sulcus. Life cycle ''Trissolcus basalis'' is a solitary endoparasitoid, completing development within the eggs of pentatomid bugs. Females use their clubbed-shape antennae to palpate eggs laid by their primary host, '' Nezara viridula''. When ready to oviposit, the female faces away from the egg and backs into it, inserting her ovipositor The ovipo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nezara Viridula
''Nezara viridula'', commonly known as the southern green stink bug (USA), southern green shield bug (UK) or green vegetable bug (Australia and New Zealand), is a plant-feeding stink bug. Believed to have originated in Ethiopia, it can now be found around the world.Squitier J.M. (1997, updated 2007) Southern green stink bug»Featured creatures, University of Florida Institute of Food and Agricultural services. Because of its preference for certain species of legumes, such as beans and soybeans, it is an economically important pest on such crops. Description The adult males can reach a body length (from front to elytral apex) of about , while females are bigger, reaching a size of about . The body is usually bright green and shield-shaped and the eyes are usually reddish, but they may also be black. There is a row of three white spots on the scutellum. They differ from the similar green stink bug (''Chinavia hilare'') by the shape of their scent gland openings, which are shor ...

Hemiptera Of Australia
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles.
