Eucalyptus is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including Corymbia, they are commonly known as eucalypts. Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut".
Eucalyptus regnans, known variously as mountain ash, swamp gum, or stringy gum, is a species of medium-sized to very tall forest tree that is native to the Australia states of Tasmania and Victoria. It is a straight-trunked tree with smooth grey bark, but with a stocking of rough brown bark at the base, glossy green, lance-shaped to curved adult leaves, flower buds in groups of between nine and fifteen, white flowers and cup-shaped or conical fruit. It is the tallest of all flowering plants; the tallest measured living specimen, named Centurion, stands 102 metres tall in Tasmania.
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 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.
Eucalyptus globulus, commonly known as southern blue gum or blue gum, is a species of tall, evergreen tree endemic to southeastern Australia. This Eucalyptus species has mostly smooth bark, juvenile leaves that are whitish and waxy on the lower surface, glossy green, lance-shaped adult leaves, glaucous, ribbed flower buds arranged singly or in groups of three or seven in leaf axils, white flowers and woody fruit.
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.
Eucalyptus grandis, commonly known as the flooded gum or rose gum, is a tall tree with smooth bark, rough at the base fibrous or flaky, grey to grey-brown. At maturity, it reaches 50 metres tall, though the largest specimens can exceed 80 metres tall. It is found on coastal areas and sub-coastal ranges from Newcastle in New South Wales northwards to west of Daintree in Queensland, mainly on flat land and lower slopes, where it is the dominant tree of wet forests and on the margins of rainforests.
Eucalyptus nitens, commonly known as shining gum or silvertop, is a species of tall tree native to Victoria and eastern New South Wales. It has smooth greyish bark, sometimes with thin, rough bark near the base, lance-shaped adult leaves, flower buds in groups of seven or nine, white flowers and cup-shaped, barrel-shaped or cylindrical fruit. It grows in wet forests and rainforest margins on fertile soils in cool, high-rainfall areas.
Paropsis is a genus of Chrysomelidae, commonly referred to as tortoise beetles, which includes over 70 described species. Their small size, bright colours and patterns, and roughly hemispherical shape cause them to be mistaken for beetles in the family Coccinellidae (ladybirds). They are distributed across Australia, New Zealand and Papua New Guinea. They primarily feed on Eucalyptus but there are a few that feed on Baeckea, Kunzea and Leptospermum. Species within this genus are noted as pests. For example, Paropsis charybdis is a pest of Eucalyptus in New Zealand.
Abantiades latipennis, known as the Pindi moth, is a species of moth in the family Hepialidae. It may also be referred to as a swift moth or a ghost moth, as this is a common name associated with Hepialidae. Endemic to Australia and identified in 1932, it is most populous in temperate rainforest where eucalypti are prevalent, as the larvae feed primarily on the roots of these trees. Females lay eggs during flight in a scattering fashion. The larvae live for over eighteen months underground, while adult moths survive for approximately one week, as they have no mouthparts with which to feed. The moths are preyed upon by a number of predators, including bats and owls. Brown in colour overall, males are paler and the identifying silver bars of the male's wings are more prominent than those of the female's, with dark margins. Male adults are generally smaller.
Gonipterus scutellatus is a species of weevil in the family Curculionidae. It is commonly known as the eucalyptus snout beetle, the eucalyptus weevil or the gum tree weevil. It feeds and breeds on Eucalyptus trees and is endemic to Australia.
Phratora is a genus of leaf beetles. It is synonymous to Phyllodecta . European Phratora species can be distinguished based on morphology of female genitalia., but they differ little in size and body form and most show metallic coloration.
The Farm Forestry Toolbox is a collection of computer programs, referred to as 'Tools', intended to be used by farm forest owners and managers to aid decision making. The Toolbox includes a set of simple 'Hand Tools'; conversion of measurements and map co-ordinates; measuring the volume of stacked logs, slope, basal area; and a survey tool. A second set of more complex tools or 'Power Tools'; can be used to estimate site productivity, volume and value of wood grown for individual trees, at the coupe or stand level and forest estate level.
Anaphes nitens is a species of fairyfly, a chalcid wasp in the family Mymaridae. Native to Australia, it is an egg parasitoid of the gum tree snout beetle, a pest of Eucalyptus trees, and has been used in biological pest control of that species.
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.
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 epipleura (skirt) is sometimes red.
Afroeurydemus selmani is a species of leaf beetle of the Democratic Republic of the Congo. It was originally described by Brian J. Selman in 1972 as Afroeurydemus signatus. In 2019, this species became a homonym of Afroeurydemus signatus(Pic, 1940), a species formerly placed in Syagrus and moved to Afroeurydemus by Stefano Zoia. Selman's species was then renamed to Afroeurydemus selmani.
Paropsisterna bimaculata is a beetle commonly called a leaf beetle in the subfamily Chrysomelinae.This insect is common in Tasmania and can be a pest in the forestry industry. Paropsisterna bimaculata will develop a red color just before their winter hibernation. When they emerge the red slowly disappears into a pale green colouring with faint gold tessellation. This takes about a month with the males generally slightly advanced. Recently this beetle has been noticed in Victoria.
Calomela is a genus of beetles commonly called leaf beetles and in the family Chrysomelidae. They are specialist feeders on various species of Acacia and are not reported as a problem species. The beetles are cylindrical when compared with other leaf beetles and their larvae are globose. Calomela includes about 45 species which are found in all states of Australia.
Anoplognathus brunnipennis, commonly known as the brown- or golden-brown Christmas beetle, is a beetle of the family Scarabaeidae native to eastern Australia, being common in coastal Queensland, New South Wales and Victoria, the Great Dividing Range and the Murray-Darling river basin.
Paropsisterna beata, commonly known as the blessed leaf beetle, is a species of leaf beetle. It occurs in all states of Australia except Tasmania.
