Paropsisterna Agricola
''Paropsisterna agricola'' or southern eucalyptus leaf beetle, is a small hemispherical leaf beetle. They can vary from golden to grey. They have some black markings on the pronotum The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on ea .... The epipleura (skirt) is sometimes red. This species has the ability to increase population very rapidly and can become a commercial pest to the timber industry attacking plantation forests.

Félicien Chapuis (29 April 1824 – 30 September 1879) was a Belgian doctor and entomologist. He specialised in Coleoptera Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota.

Paropsisterna Agricola Exton11-001
''Paropsisterna'' is a genus of leaf beetles indigenous to Papua New Guinea and Australia. There are over 120 species, many with bright aposematic colours, and many feeding on '' Eucalyptus'' leaves. The genus was described by Victor Motschulsky in 1860. Description ''Paropsisterna'' are beetles 3-17 mm long with bodies semicircular to elongate-ovate and moderately to strongly convex. The frontoclypeal suture is rounded or V-shaped, and lacks lateral ridges. The apical maxillary palpomere is strongly expanded from base to truncate apex. The pronotum is broadest at its base. The procoxal cavity is open with a gap at least half the width of the procoxa. The mid and hind tibiae have at least one sharp external longitudinal keel. The tarsal claws are usually acutely toothed, rarely simple. Some species are very colourful, but their colours may fade after death. Diet This genus of beetles feeds on plants in family Myrtaceae, including '' Acmena'', '' Agonis'', ''Angophora'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Beetle
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research. Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the fourth tarsal segment is very small and hidden by the third. As with many taxa, no single character defines the Chrysomelidae; instead, the family is delineated by a set of characters. Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles. Adult and larval leaf beetles feed on all sorts of plant tissue, and all species are fully herbivorous. Many are serious pests of cultivated plants, f ...

Prothorax
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also *Glossary of entomolo ...

Forestry Tasmania
Sustainable Timber Tasmania (formerly Forestry Tasmania) is a government business enterprise wholly owned by the Government of Tasmania, Australia. It is responsible for the management of public production forest in Tasmania, which is about 800,000 hectares of crown land (public land) that is classified as 'permanent timber production zone'. The company was first established in 1994, although it has earlier historical origins from operations undertaken by the state government. Sustainable Timber Tasmania is overseen by a Board of Management who are responsible to the Treasurer and the Minister for Forests. History The passing of the ''State Forests Act 1885'' marked the beginning of regular reporting of forest management activities in Tasmania, conducted by Lands and Surveys Department until the formation of the Forestry Department in 1921. Research activities in the 1920s were mainly directed at assessing and mapping the State's commercial timber resources. Ground mapping w ...

Beetles Of Australia
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exoske ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysomelinae
The Chrysomelinae are a subfamily of leaf beetles (Chrysomelidae), commonly known as broad-bodied leaf beetles or broad-shouldered leaf beetles. It includes some 3,000 species around the world. The best-known member is the notorious Colorado potato beetle (''Leptinotarsa decemlineata''), an important agricultural pest. Description Adults of Chrysomelinae are beetles with the following features: antennae inserted on or adjacent to anterior edge of head; inner face of each mandible with large membranous prostheca; each wing with only one anal cell (sometimes the wings are reduced or absent); metendosternite lateral arms without lobes; femora without internal spring sclerite; tibial spurs absent; tarsi without bifid setae; stridulatory mechanism absent; male aedeagus without tegminal ring and the testes not fused within a common membrane; female kotpresse absent.
