Xylocopa aerata, the golden-green carpenter bee or green carpenter bee, is one of two species of carpenter bee found only in the conservation areas around Sydney, and in the Great Dividing Range in New South Wales in Australia. Its only other habitat as of 2020 is on Kangaroo Island in South Australia. The species is especially vulnerable to fire, and much of its habitat was burnt during the 2019–20 Australian bushfire season.
The bee gets its common name by its habit of burrowing into wood. It is not a social species and does not produce honey, but it is an important pollinator for several species of Australian native plants.
It was originally described by F. Smith in 1851 as Lestis aeratus. [1] Its specific epithet is the Latin adjective aerata, meaning "bronzed".
As its name implies, the golden-green carpenter bee is a metallic green in colour, although it may appear purplish or bluish from some angles. A large stocky bee (at nearly 2 cm (0.79 in), one of the largest native bees in southern Australia [2] ), it is often heard by its loud low-pitched buzzing while flying between flowers. The male has yellow face markings. The bee does have a sting which is potentially painful, although no stings have been recorded. [3]
The natural distribution was southeastern New South Wales from Sydney southwards (where it overlaps with X. bombylans ), and into Victoria and southeastern South Australia. [4] However, the green carpenter bee went extinct on mainland South Australia in 1906 and in Victoria in 1938. Apart from conservation areas around Sydney, and in the Great Dividing Range, it exists only on the western half of Kangaroo Island in SA. [2]
They can be seen from spring to autumn, commonly feeding at pea flowers of the family Fabaceae, such as Gompholobium species, including Gompholobium latifolium in spring, and Pultenaea elliptica in autumn. Flowers of Leucopogon and Leptospermum are also visited. [4]
The golden-green carpenter bee nests by hollowing out stalks of grasstrees ( Xanthorrhoea ), or soft wood such as Banksia , Casuarina , Melaleuca and Leptospermum. The female excavates a tunnel with her jaws and picks up and dumps the wood shavings outside. The hollow can reach 30 cm (12 in) long by 1.1-1.4 cm diameter. Larger pieces of wood may allow for multiple tunnels. Several female bees may use a nest, one breeding and the others guarding. A bee defends the 0.7-1.0 cm wide entrance by blocking it with its abdomen (compare Allodapula ). Both male and female bees may overwinter within the tunnels. The tunnels are partitioned into several cells, where the mother bee lays an egg in each accompanied by provisions of nectar and pollen. [3]
Habitat clearing and large, intense bushfires led to extinction in some areas. The last green carpenter bee seen in Victoria was in December 1938 in the Grampians, not long before the Black Friday fires of January 1939. Fire destroys the dead wood the bee needs for nesting, and the flowers which it needs all the time. [2]
In 2007 a huge fire destroyed much of the vegetation in Flinders Chase National Park on Kangaroo Island, but left dry grass-tree stalks in the adjacent areas which were colonised by the bees. Conservationists also developed artificial nesting stalks to support the bee population until new banksia became available, which were placed in the fire-affected areas where the bee still occurred. Almost 300 female carpenter bees used the artificial stalks to raise their young, until disaster struck in the 2019–20 Australian bushfire season. Not only were the areas of the artificial stalks destroyed, but much of the old banksia habitat on Kangaroo Island, and the NSW fires destroyed large areas of habitat there too. [2]
Banksia is a genus of around 170 species of flowering plants in the family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes, and woody fruiting "cones" and heads. Banksias range in size from prostrate woody shrubs to trees up to 30 metres (100 ft) tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts.
Carpenter bees are species in the genus Xylocopa of the subfamily Xylocopinae. The genus includes some 500 bees in 31 subgenera. The common name "carpenter bee" derives from their nesting behavior; nearly all species burrow into hard plant material such as dead wood or bamboo. The main exceptions are species in the subgenus Proxylocopa, which dig nesting tunnels in suitable soil.
Banksia serrata, commonly known as the saw banksia, the old man banksia, the saw-tooth banksia or the red honeysuckle and as wiriyagan by the Cadigal people, is a species of woody shrub or tree of the genus Banksia, in the family Proteaceae. Native to the east coast of Australia, it is found from Queensland to Victoria with outlying populations on Tasmania and Flinders Island. Commonly growing as a gnarled tree up to 16 m (50 ft) in height, it can be much smaller in more exposed areas. This Banksia species has wrinkled grey bark, shiny dark green serrated leaves and large yellow or greyish-yellow flower spikes appearing over summer. The flower spikes, or inflorescences, turn grey as they age and pollinated flowers develop into large, grey, woody seed pods called follicles.
Banksia ericifolia, the heath-leaved banksia, or lantern banksia, is a species of woody shrub of the family Proteaceae native to Australia. It grows in two separate regions of Central and Northern New South Wales east of the Great Dividing Range. Well known for its orange or red autumn inflorescences, which contrast with its green fine-leaved heath-like foliage, it is a medium to large shrub that can reach 6 m (20 ft) high and wide, though is usually half that size. In exposed heathlands and coastal areas, it is more often 1–2 m (3.3–6.6 ft).
Banksia aemula, commonly known as the wallum banksia, is a shrub of the family Proteaceae. Found from Bundaberg south to Sydney on the Australian east coast, it is encountered as a shrub or a tree to 8 m (26 ft) in coastal heath on deep sandy soil, known as Wallum. It has wrinkled orange bark and shiny green serrated leaves, with green-yellow flower spikes, known as inflorescences, appearing in autumn. The flower spikes turn grey as they age and large grey follicles appear. Banksia aemula resprouts from its woody base, known as a lignotuber, after bushfires.
Banksia aculeata, commonly known as prickly banksia, is a species of plant of the family Proteaceae native to the Stirling Range in the southwest of Western Australia. A shrub up to 2 m (7 ft) tall, it has dense foliage and leaves with very prickly serrated margins. Its unusual pinkish, pendent (hanging) flower spikes, known as inflorescences, are generally hidden in the foliage and appear during the early summer. Although it was collected by the naturalist James Drummond in the 1840s, Banksia aculeata was not formally described until 1981, by Alex George in his monograph of the genus.
Banksia oblongifolia, commonly known as the fern-leaved, dwarf or rusty banksia, is a species in the plant genus Banksia. Found along the eastern coast of Australia from Wollongong, New South Wales in the south to Rockhampton, Queensland in the north, it generally grows in sandy soils in heath, open forest or swamp margins and wet areas. A many-stemmed shrub up to 3 m (9.8 ft) high, it has leathery serrated leaves and rusty-coloured new growth. The yellow flower spikes, known as inflorescences, most commonly appear in autumn and early winter. Up to 80 follicles, or seed pods, develop on the spikes after flowering. Banksia oblongifolia resprouts from its woody lignotuber after bushfires, and the seed pods open and release seed when burnt, the seed germinating and growing on burnt ground. Some plants grow between fires from seed shed spontaneously.
Banksia paludosa, commonly known as the marsh or swamp banksia, is a species of shrub in the plant genus Banksia. It is native to New South Wales, Australia, where it is found between Sydney and Batemans Bay, with an isolated population further south around Eden. There are two recognised subspecies, the nominate of which is a spreading shrub to 1.5 m (4.9 ft) in height, and subsp. astrolux is a taller shrub to 5 m (16 ft) high found only in Nattai National Park.
Banksia telmatiaea, commonly known as swamp fox banksia or rarely marsh banksia, is a shrub that grows in marshes and swamps along the lower west coast of Australia. It grows as an upright bush up to 2 metres tall, with narrow leaves and a pale brown flower spike, which can produce profuse quantities of nectar. First collected in the 1840s, it was not published as a separate species until 1981; as with several other similar species it was previously included in B. sphaerocarpa.
The ecology of Banksia is the relationships and interactions among the plant genus Banksia and its environment. Banksia has a number of adaptations that have so far enabled the genus to survive despite dry, nutrient-poor soil, low rates of seed set, high rates of seed predation and low rates of seedling survival. These adaptations include proteoid roots and lignotubers; specialised floral structures that attract nectariferous animals and ensure effective pollen transfer; and the release of seed in response to bushfire.
Eucalyptus botryoides, commonly known as the bangalay, bastard jarrah, woollybutt or southern mahogany, is a small to tall tree native to southeastern Australia. Reaching up to 40 metres high, it has rough bark on its trunk and branches. It is found on sandstone- or shale-based soils in open woodland, or on more sandy soils behind sand dunes. The white flowers appear in summer and autumn. It reproduces by resprouting from its woody lignotuber or epicormic buds after bushfire. E. botryoides hybridises with the Sydney blue gum in the Sydney region. The hard, durable wood has been used for panelling and flooring.
Angophora hispida grows as a mallee, or as a tree to about 7 m (25 ft) in height. A. hispida's small size, especially when compared to its Angophora and Eucalyptus relatives, leads to it being known by the common name dwarf apple. It is native to a relatively small patch of central New South Wales – from just south of Sydney up to the Gosford area. The plant's leaves are sessile (stalk-less) and hug the stem with heart-shaped bases. Its previous name – A. cordifolia – referred to these cordate leaves. Another distinctive feature is the red bristly hairs that cover the branchlets, flower bases and new growth. This leads to the specific epithet hispida.
Lambertia formosa, commonly known as mountain devil, is a shrub of the family Proteaceae, endemic to New South Wales, Australia. First described in 1798 by English botanist James Edward Smith, it is the type species of the small genus Lambertia. It is generally found in heathland or open forest, growing in sandstone-based soils. It grows as a multistemmed shrub to around 2 m (7 ft) with a woody base known as a lignotuber, from which it regrows after bushfire. It has stiff narrow leaves, and the pink to red flowerheads, made up of seven individual tubular flowers, generally appear in spring and summer. It gains its common name from the horned woody follicles, which were used to make small devil-figures.
Xylocopa sonorina, the valley carpenter bee or Hawaiian carpenter bee, is a species of carpenter bee found from western Texas to northern California, and the eastern Pacific islands. Females are black while males are golden-brown with green eyes.
Telopea mongaensis, commonly known as the Monga waratah or Braidwood waratah, is a shrub or small tree in the family Proteaceae. Endemic to Australia, it grows at high altitude in south eastern New South Wales, where it is often seen in moist areas at the edge of rainforest or by streams in eucalyptus forests. Growing to 6 m (20 ft) high, it has narrow green leaves 4–18 cm (1.6–7.1 in) in length, and 0.5–2 cm (0.20–0.79 in) wide. In spring bears many red flowerheads, each made up of 28 to 65 individual flowers.
Xylocopa bombylans, the peacock carpenter bee, is a species of carpenter bee found in Australia. It gets its common name by its habit of burrowing into wood.
Persoonia linearis, commonly known as the narrow-leaved geebung, is a shrub native to New South Wales and Victoria in eastern Australia. It reaches 3 m (9.8 ft), or occasionally 5 m (16 ft), in height and has thick, dark grey papery bark. The leaves are, as the species name suggests, more or less linear in shape, and are up to 9 cm (3.5 in) long, and 0.1 to 0.7 cm wide. The small yellow flowers appear in summer, autumn and early winter, followed by small green fleshy fruit known as drupes. Within the genus Persoonia, it is a member of the Lanceolata group of 58 closely related species. P. linearis interbreeds with several other species where they grow together.
Persoonia lanceolata, commonly known as lance-leaf geebung, is a shrub native to New South Wales in eastern Australia. It reaches 3 m (10 ft) in height and has smooth grey bark and bright green foliage. Its small yellow flowers grow on racemes and appear in the austral summer and autumn, followed by green fleshy fruits which ripen the following spring. Within the genus Persoonia, P. lanceolata belongs to the lanceolata group of 58 closely related species. It interbreeds with several other species found in its range.
Persoonia chamaepitys, commonly known as the prostrate- or mountain geebung, is a shrub endemic to New South Wales in eastern Australia. It has a prostrate habit, reaching only 20 cm (7.9 in) high but spreading up to 2 m (6.6 ft) across, with bright green spine-like leaves and small yellow flowers appearing in summer and autumn.
Xylocopa latipes, the broad-handed carpenter bee, is a species of carpenter bee widely dispersed throughout Southeast Asia. This bee inhabits forests and constructs nests by burrowing into wood. It often makes long deep tunnels in wooden rafters, fallen trees, telephone poles, etc., but is not found in living trees.
