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.
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.
Eucalyptus oil is the generic name for distilled oil from the leaf of Eucalyptus, a genus of the plant family Myrtaceae native to Australia and cultivated worldwide. Eucalyptus oil has a history of wide application, as a pharmaceutical, antiseptic, repellent, flavouring, fragrance and industrial uses. The leaves of selected Eucalyptus species are steam distilled to extract eucalyptus oil.
The Cassidinae are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra.
Eucalyptus macrocarpa, commonly known as mottlecah, is a species of mallee that is endemic to the south-west of Western Australia. It has smooth bark, usually sessile, heart-shaped adult leaves arranged in opposite pairs, large red flowers and broad conical fruit.
The Cryptocephalini are a tribe within the leaf beetle subfamily Cryptocephalinae. As the other Cryptocephalinae, they belong to the group of case-bearing leaf beetles known as Camptosomata. Some species are myrmecophilous.
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.
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.
Eucalyptus wandoo, commonly known as wandoo, dooto, warrnt or wornt and sometimes as white gum is a small to medium-sized tree that is endemic to the southwest of Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of nine to seventeen, white flowers and conical to cylindrical fruit. It is one of a number of similar Eucalyptus species known as wandoo.
Oxyops vitiosa is a species of weevil in the family Curculionidae. Common names include the melaleuca leaf weevil and the melaleuca snout beetle. It feeds on the leaves and shoots of the broad-leaved paper bark tree, Melaleuca quinquenervia, which is endemic to Australia where it grows on seasonally inundated plains and swampland, and was introduced into Florida in order to help drain flooded portions of the Everglades.
Saunders' case moth or the large bagworm is a moth of the Psychidae family. It is known from the eastern half of Australia, including Tasmania.
The fecal shield is a structure formed by the larvae of many species of beetles in the leaf beetle family, Chrysomelidae. It is composed of the frass of the insect and often its exuviae, or bits of shed exoskeleton. The beetle may carry the shield on its back or wield it upon its posterior end. The main function of the fecal shield is defense against predators. Other terms for the fecal shield noted in the literature include "larval clothing", "kotanhang", "faecal mask", "faecal pad", and "exuvio-faecal annex".
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 selmani, the Tasmanian Eucalyptus Beetle, is a species of leaf beetle native to Tasmania which has been inadvertently introduced to the Republic of Ireland and United Kingdom. It is the first eucalyptus-feeding chrysomelid known to have become established in Europe.
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 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.
Cadmus is a genus of leaf beetles which are commonly called case bearing leaf beetles in the subfamily Chrysomelinae. They are widespread throughout Australia and include 5 subgenera and 68 species.
Myrabolia is the only genus in the beetle family Myraboliidae in the superfamily Cucujoidea. It has about 13 species, found in Australia. Adults and possibly larvae live under the bark of Eucalyptus trees.
Paropsisterna beata, commonly known as the blessed leaf beetle, is a species of leaf beetle. It occurs in all states of Australia except Tasmania.
