Hylaeus Sanguinipictus
''Hylaeus sanguinipictus'' is a bee species endemic to Western Australia. It was described in 1914 from material collected in Yallingup by Theodore Dru Alison Cockerell as ''Prosopis sanguinipicta''. Like its relative the banksia bee (''Hylaeus alcyoneus ''Hylaeus alcyoneus'', commonly known as the banksia bee, is a bee species endemic to Australia where it is commonly found in the coastal heaths of eastern and southern Western Australia. This bee is an important pollinator of '' Banksia'' spec ...''), ''H. sanguinipictus's'' expression of sexual dimorphism is unusual — the males of the species are larger than the females; in most other types of bee, females are larger than males. The males perch and defend ''Banksia'' inflorescences while waiting to mate with females, and combat other males. Western Australian banksias that the bee has been recorded visiting include '' B. menziesii'' and '' B. prionotes''. References {{Taxonbar, from=Q2412430 Colletidae Hymenopt ...

Theodore Dru Alison Cockerell
Theodore Dru Alison Cockerell (1866–1948) was an American zoology, zoologist, born at Norwood, England, and brother of Sydney Cockerell. He was educated at the Middlesex Hospital Medical School, and then studied botany in the field in Colorado in 1887–90. Subsequently, he became a taxonomist and published numerous papers on the Hymenoptera, Hemiptera, Mollusca and plants, as well as publications on paleontology and evolution. Personal life Cockerell was born in Norwood, Greater London and died in San Diego, California. He married Annie Sarah Fenn in 1891 (she died in 1893) and Wilmatte Porter Cockerell, Wilmatte Porter in 1900. In 1901, he named the ultramarine blue chromodorid ''Mexichromis porterae'' (now ''Felimare porterae'') in her honor. After their marriage in 1900, they frequently went on collecting expeditions together and assembled a large private library of natural history films, which they showed to schoolchildren and public audiences to promote the cause of en ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ...

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 the ...

Hylaeus Alcyoneus
''Hylaeus alcyoneus'', commonly known as the banksia bee, is a bee species endemic to Australia where it is commonly found in the coastal heaths of eastern and southern Western Australia. This bee is an important pollinator of '' Banksia'' species. The banksia bee was originally described by German entomologist Wilhelm Ferdinand Erichson in 1842; its specific epithet is derived from the Ancient Greek ''halcyon'' "kingfisher" relating to its kingfisher blue colour. The banksia bee has a metallic blue abdomen and yellow face markings. The sexual dimorphism of this species is notable amongst bees — the males of the species are significantly larger than the females; in most other types of bee, females are larger than males. Males of different sizes have been shown to display different feeding behaviour. Large males perch and defend ''Banksia'' inflorescences that are in high positions on the shrub where they feed; small males feed closer to the ground and patrol circuits incl ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Banksia Menziesii
''Banksia menziesii'', commonly known as firewood banksia, is a species of flowering plant in the genus ''Banksia''. It is a gnarled tree up to tall, or a lower spreading shrub in the more northern parts of its range. The serrated leaves are dull green with new growth a paler grey green. The prominent autumn and winter inflorescences are often two-coloured red or pink and yellow, and their colour has given rise to more unusual common names such as port wine banksia and strawberry banksia. Yellow blooms are rarely seen. First described by the botanist Robert Brown in the early 19th century, no separate varieties of ''Banksia menziesii'' are recognised. It is found in Western Australia, from the Perth (32° S) region north to the Murchison River (27° S), and generally grows on sandy soils, in scrubland or low woodland. ''Banksia menziesii'' provides food for a wide array of invertebrate and vertebrate animals; birds and in particular honeyeaters are prominent visitors. A re ...

Banksia Prionotes
''Banksia prionotes'', commonly known as acorn banksia or orange banksia, is a species of shrub or tree of the genus ''Banksia'' in the family Proteaceae. It is native to the southwest of Western Australia and can reach up to in height. It can be much smaller in more exposed areas or in the north of its range. This species has serrated, dull green leaves and large, bright flower spikes, initially white before opening to a bright orange. Its common name arises from the partly opened inflorescence, which is shaped like an acorn. The tree is a popular garden plant and also of importance to the cut flower industry. ''Banksia prionotes'' was first described in 1840 by English botanist John Lindley, probably from material collected by James Drummond the previous year. There are no recognised varieties, although it has been known to hybridise with ''Banksia hookeriana''. Widely distributed in south-west Western Australia, ''B. prionotes'' is found from Shark Bay ( 25° S) in th ...

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 spe ...

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 ...

Insects Described In 1914
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from ...
