Hesperocolletes
''Hesperocolletes douglasi'', the Rottnest bee or Douglas's broad-headed bee, is a rediscovered species of plasterer bee that is endemic to Australia, and the sole known member of the genus ''Hesperocolletes''. It was described from a single specimen collected in 1938 on Rottnest Island, located off the coast of Western Australia. A second specimen was found in 2015, in ''Banksia'' woodland at Pinjar, Western Australia. Description The bee's body is black, shiny and 12 mm long and wings were brown and up to 8 mm long. It is about the same size as a honeybee. It is generally black and brown and moderately hairy. ''Hesperocolletes douglasi'' is superficially like a number of other native bees and careful examination under a microscope would be required to distinguish a specimen. Taxonomy Bee expert Charles Michener described and named the species in 1965 on the basis of the 1938 specimen, designating it as the holotype, and created the monotypic genus ''Hesperocolle ...

Colletidae
The Colletidae are a family of bees, and are often referred to collectively as plasterer bees or polyester bees, due to the method of smoothing the walls of their nest cells with secretions applied with their mouthparts; these secretions dry into a cellophane-like lining.C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, pg. 133, Johns Hopkins University Press. The five subfamilies, 54 genera, and over 2000 species are all (with the known exception of but one species, '' Amphylaeus morosus'') evidently solitary, though many nest in aggregations. Two of the subfamilies, Euryglossinae and Hylaeinae, lack the external pollen-carrying apparatus (the scopa) that otherwise characterizes most bees, and instead carry the pollen in their crops. These groups, and most genera in this family, have liquid or semiliquid pollen masses on which the larvae develop. They can be found all over the world, but the most species live in South America and Australia. Over 50% of all bee spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fauna Of Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera Of Australia
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Native Bees
Australia has over 1,700 species of native bee. Bees collect pollen from flowers to feed their young. Flies do not do this, although they may be seen ''eating'' pollen, so identification is not always easy. Sting or no sting, solitary vs social Eleven of the species, the social native bees, are in two genera, ''Tetragonula'' and '' Austroplebeia'', and have no sting. Of the remainder, which live solitary lives, none are aggressive, and most cannot actually use their sting on humans because they are too small to do so. Larger examples of Australian native bee are capable of stinging if handled or squashed. The stings of most Australian native species of bee will cause relatively minor discomfort to most people -- "not as painful as those of a bull ant or paper wasp and last only a few minutes". However, they may sting more than once, and can cause an allergic reaction—increasing effect associated with repeated exposure to the antigen. Honey None of the native spec ...

Human Impact On The Environment
Human impact on the environment (or anthropogenic impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of built environment, society is causing severe effects including global warming, environmental degradation (such as ocean acidification), Holocene extinction, mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing Global catastrophic risk, catastrophic risks to the survival of the human species. The term ''anthropogenic'' designates an effect or object resulting from human activity. The term was first used in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Labrum (arthropod Mouthpart)
The labrum is a flap-like structure that lies immediately in front of the mouth in almost all extant Euarthropoda. The most conspicuous exceptions are the Pycnogonida, which probably are chelicerate-relatives. In entomology, the labrum amounts to the "upper lip" of an insect mouth, the corresponding "lower lip" being the labium. The evolutionary origin, embryogenesis and morphological development of the labrum have proved to be by far the most controversial and challenging topic in the study of arthropod head structures. Embryonic nature and origin of the labrum The labrum is innervated in crustaceans and insects from the tritocerebrum (the back of the brain). However, in development, its embryonic primordium often appears at the anterior of the head and migrates backwards towards its adult position. Furthermore, it often appears as a bilobed structure, with a set of muscles, nerves and gene expression in many ways similar to that of an appendage. This evidence has been ...

Proboscis
A proboscis () is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular mouthparts used for feeding and sucking. In vertebrates, a proboscis is an elongated nose or snout. Etymology First attested in English in 1609 from Latin , the latinisation of the Ancient Greek (), which comes from () 'forth, forward, before' + (), 'to feed, to nourish'. The plural as derived from the Greek is , but in English the plural form ''proboscises'' occurs frequently. Invertebrates The most common usage is to refer to the tubular feeding and sucking organ of certain invertebrates such as insects (e.g., moths, butterflies, and mosquitoes), worms (including Acanthocephala, proboscis worms) and gastropod molluscs. Acanthocephala The Acanthocephala or thorny-headed worms, or spiny-headed worms are characterized by the presence of an eversible proboscis, armed with spines, which it uses to pierce an ...
