Paropsisterna Annularis
''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] |
Paropsisterna Beata
''Paropsisterna beata'', commonly known as the blessed leaf beetle, is a species of leaf beetle. It occurs in all states of Australia except Tasmania. Description ''Paropsisterna beata'' is a mostly black beetle except for an orange head, orange margins on the pronotum, a narrow orange "skirt" around the elytra, and each elytron having three orange blotches. Sometimes, two of the blotches on each elytron are joined, especially in the north of the species' range. There are extremely fine puncturations and striae. There is a subspecies, ''P. beata rubrosignata,'' in which the elytral blotches are more yellowish and the marginal colouring is thicker and more reddish. Some other species in the genus resemble ''P. beata'' but can be distinguished by certain features: '' P. sexpustulata'' lacks the colored lateral skirt and '' P. octosignata'' has an entirely black pronotum. Life cycle and diet As a beetle, ''P. beata'' undergoes complete metamorphosis with the four life stages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callistemon
''Callistemon'' is a genus of shrubs in the family Myrtaceae, first described as a genus in 1814. The entire genus is endemic to Australia but widely cultivated in many other regions and naturalised in scattered locations. Their status as a separate taxon is in doubt, some authorities accepting that the difference between callistemons and melaleucas is not sufficient for them to be grouped in a separate genus. Description ''Callistemon'' species have commonly been referred to as bottlebrushes because of their cylindrical, brush like flowers resembling a traditional bottle brush. They are mostly found in the more temperate regions of Australia, especially along the east coast and typically favour moist conditions so when planted in gardens thrive on regular watering. However, two species are found in Tasmania and several others in the south-west of Western Australia. At least some species are drought-resistant and some are used in ornamental landscaping elsewhere in the world. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Dalrympleana
''Eucalyptus dalrympleana'', commonly known as mountain gum, mountain white gum, white gum and broad-leaved ribbon gum, is a species of tree that is endemic to southeastern Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of three or seven, white flowers and cup-shaped, bell-shaped or hemispherical fruit. Description ''Eucalyptus dalrympleana'' is a tree that typically grows to a height of and forms a lignotuber. It has smooth white to yellowish bark, sometimes with a short stocking of rough bark. Young plants and coppice regrowth have leaves arranged in opposite pairs and are egg-shaped or heart-shaped to more or less round, long and wide. Adult leaves are arranged alternately, lance-shaped to curved, the same colour on both sides, long and wide on a petiole long. The flower buds are arranged in groups of three or seven in leaf axils on a peduncle long, the individual buds sessile or on a pedicel up to long. Mature buds are oval, green to ye ...

Eucalyptus Delegatensis
''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". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have ...
