Hylaeus Perkinsianus
''Hylaeus perkinsianus'', commonly known as Perkin's yellow-faced bee, is a species of yellow-faced bee in the family Colletidae. It was described by Philip Hunter Timberlake in 1926, and named for Robert Cyril Layton Perkins. The species is entirely endemic to the island of Nīhoa, Hawaiian Islands, whose range covers most of the island. It is listed by the Center for Biological Diversity The Center for Biological Diversity is a nonprofit membership organization known for its work protecting endangered species through legal action, scientific petitions, creative media and grassroots activism. It was founded in 1989 by Kieran Suck ... as ''Declining and Threatened''. It is described as being medium-sized with clear wings. The face of the male has yellow markings while the female's is simply black with no markings. References Colletidae Insects of Hawaii Taxa named by Philip Hunter Timberlake {{Bee-stub ...

Hylaeus (bee)
''Hylaeus'' is a large (over 500 species) and diverse cosmopolitan genus within the bee family Colletidae. This genus is also known as the yellow-faced bees or masked bees. This genus is the only truly globally distributed colletid, occurring on all continents except Antarctica. Description The genus of bees consists of generally small, black-and-yellow or black-and-white wasp-like species. The resemblance to wasps is enhanced by the absence of a scopa, which is atypical among bees. The body form of this genus is described as hylaeiform (slender); the hairs inconspicuous without magnification; and scopa inconspicuous or absent. Males have an intermediate glossal shape with a small to distinct median apical glossal point. ''Hylaeus'' carry pollen in the crop, rather than externally, and regurgitate it into the cell where it will be used as larval food. Like most colletids, the liquid provisions are sealed inside a membranous cellophane-like cell lining. Nests are typically made ...

Colletidae
The Colletidae are a family (biology), 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 evidently solitary (with the known exception of but one species, ''Amphylaeus morosus''), though many nest in aggregations. Two of the subfamilies, Euryglossinae and Hylaeinae, lack the external pollen-carrying apparatus (the scopa (biology), 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 Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philip Hunter Timberlake
Philip Hunter Timberlake (1883-1981) was one of the most prolific American entomologists of the 20th century. He was born on June 5, 1883, in Bethel, Maine, and died in 1981 in Riverside, California, where he had served as an Associate Entomologist in the Department of Entomology of the University of California, Riverside. He obtained an A.B. degree in 1908 in Liberal Arts from Bowdoin College with a major in Greek and Latin. In 1910 he received an A.M. degree in biology from Harvard University. From 1909 to 1914, Timberlake was employed by the U.S. Department of Agriculture Bureau of Entomology, as "Agent and Expert" conducting research in biological control of pest insects. From 1914 to 1924 he was Associate Entomologist at the Hawaiian Sugar Planters Experiment Station in Honolulu, where his research dealt primarily with biological control using parasites and predators. In 1924 he was appointed Associate Entomologist in the Department of Biological Control at the Citrus Experi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Cyril Layton Perkins
Robert Cyril Layton Perkins FRS (15 November 1866 – 29 September 1955) was a distinguished British entomologist, ornithologist, and naturalist noted for his work on the fauna of the islands of Hawaii and on Hymenoptera. He is not to be confused with his son John Frederick Perkins, also a hymenopterist. Life Perkins was born on 15 November 1866 at Badminton, Gloucestershire and was educated at King Edward VI Grammar School, St. Albans – his father, Rev Charles Perkins, was the headmaster – and at Merchant Taylors' School before obtaining a scholarship in classics to Jesus College, Oxford in 1885. After two years of studying classics, he switched to reading Natural History, notwithstanding that he had not studied science at school, having been inspired to make the change by the lectures of Edward Poulton on the colour of insects. His first publications in natural history journals came when he was still studying classics. He obtained a fourth-class degree in th ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Nīhoa
Nīhoa, also written Nihoa and also known as Bird Island or Moku Manu, is the tallest of ten islands and atolls in the uninhabited Northwestern Hawaiian Islands (NWHI). The island is located at the southern end of the NWHI chain, southeast of Necker Island. Nīhoa is the closest NWHI in proximity to the eight main windward Hawaiian Islands at approximately northwest of the island of Kauai. The island has two peaks, Miller's Peak in the west, and Tanager Peak in the east. Nīhoa's area is about and is surrounded by a coral reef. Its jagged outline gives the island its name, from Hawaiian "toothed, serrated". The island is home to 25 species of plants and several animals, making it the most diverse island in the entire NWHI. Endemic birds like the Nīhoa finch and Nīhoa millerbird, and endemic plants like ''Pritchardia remota'' and ''Schiedea verticillata'' are found only on Nīhoa. ''Amaranthus brownii'' was considered the rarest plant on Nīhoa and has not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Islands
The Hawaiian Islands () are an archipelago of eight major volcanic islands, several atolls, and numerous smaller islets in the Pacific Ocean, North Pacific Ocean, extending some from the Hawaii (island), island of Hawaii in the south to northernmost Kure Atoll. Formerly called the Sandwich Islands by Europeans, the present name for the archipelago is derived from the name of its largest island, Hawaii. The archipelago sits on the Pacific Plate. The islands are exposed peaks of a great undersea mountain range known as the Hawaiian–Emperor seamount chain, formed by volcano, volcanic activity over the Hawaiian hotspot. The islands are about from the nearest continent and are part of the Polynesia subregion of Oceania. The U.S. state of Hawaii occupies the archipelago almost in its entirety (including the mostly uninhabited Northwestern Hawaiian Islands), with the sole exception of Midway Atoll (a United States Minor Outlying Island). Hawaii is the only U.S. state that is sit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Center For Biological Diversity
The Center for Biological Diversity is a nonprofit membership organization known for its work protecting endangered species through legal action, scientific petitions, creative media and grassroots activism. It was founded in 1989 by Kieran Suckling, Peter Galvin, Todd Schulke and Robin Silver.

Insects Of Hawaii
Insects (from Latin ') are 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 a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. Th ...
