Eupholus Azureus
''Eupholus azureus'' is a species of beetles belonging to the family Curculionidae. Description ''Eupholus azureus'' can reach a length of about . The elytra are broader than the thorax at the base and pointed at the apex. There are nine rows of large regular deep punctures on each elytron. The scutellum is very small and round. Eupholus azureus is slightly mottled black. The turquoise colour derives from very small scales.Denis Llewellyn Fox Animal Biochromes and Structural Colours/ref> The thorax shows two smooth black lines on each sides of the median sulcus. Usually there are one or two transverse bands (one is larger) a little behind the middle and not reaching the suture. The suture, the scutellar region and the transverse bands are black. Legs are azure and the knee joins are black. Antennae are partially covered with tiny whitish sensory hair, while the club is brown or black. This species is characterized by sexual dimorphism, with males having a pronotum widely rounded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Sharp Macleay
William Sharp Macleay or McLeay (21 July 1792 – 26 January 1865) was a British civil servant and entomologist. He was a prominent promoter of the Quinarian system of classification. After graduating, he worked for the British embassy in Paris, following his interest in natural history at the same time, publishing essays on insects and corresponding with Charles Darwin. Macleay moved to Havana, Cuba, where he was, in turn, commissioner of arbitration, commissary judge, and then judge. Retiring from this work, he emigrated to Australia, where he continued to collect insects and studied marine natural history. Early life Macleay was born in London, eldest son of Alexander Macleay, who named him for his then business partner, fellow wine merchant William Sharp. He attended Westminster School and Trinity College, Cambridge, graduating with honours in 1814. He was then appointed attaché to the British embassy at Paris, and secretary to the board for liquidating British claims o ...

Curculionidae
The Curculionidae are a family of weevils, commonly called snout beetles or true weevils. They are one of the largest animal families, with 6,800 genera and 83,000 species described worldwide. They are the sister group to the family Brentidae. They include the bark beetles as the subfamily Scolytinae, which are modified in shape in accordance with their wood-boring lifestyle. They do not much resemble other weevils, so they were traditionally considered a distinct family, Scolytidae. The family also includes the ambrosia beetles, of which the present-day subfamily Platypodinae was formerly considered the distinct family Platypodidae. Description Adult Curculionidae can be recognised by the well-developed, downwards-curved snout (Rostrum (anatomy), rostrum) possessed by many species, though the rostrum is sometimes short (e.g. Entiminae). They have elbowed Antenna (biology), antennae that end in clubs, and the first antennal segment often fits into a groove in the side of the ros ...

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 exaggerat ...

Papua New Guinea
Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia (a region of the southwestern Pacific Ocean north of Australia). Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of . At the national level, after being ruled by three external powers since 1884, including nearly 60 years of Australian administration starting during World War I, Papua New Guinea established its sovereignty in 1975. It became an independent Commonwealth realm in 1975 with Elizabeth II as its queen. It also became a member of the Commonwealth of Nations in its own right. There are 839 known languages of Papua New Guinea, on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entiminae
The Entiminae are a large subfamily in the weevil family Curculionidae, containing most of the short-nosed weevils, including such genera as '' Entimus'', '' Otiorhynchus'', '' Phyllobius'', '' Sitona'', and '' Pachyrrhynchus''. In comparison with their stunning diversity, only a few of these weevils are notorious pests of major economic importance. Entimines are commonly encountered in the field, including urban environments, and abundant in entomological collections. Diversity There are over 12000 described species worldwide, distributed in over 1370 genera, nearly 14000 by more recent counts. Most tribes are represented in only one biogeographic region of the world. The current classification within the subfamily has been recognized as artificial rather than reflecting natural groups. General morphology Besides the shape of their broad and short rostrum, most entimines are easily recognized by the presence of a mandibular scar that appears when a deciduous process falls ...
