Helaeomyia Petrolei
The petroleum fly, ''Helaeomyia petrolei'' (synonym ''Diasemocera petrolei''), is a species of fly from California, USA. The larvae feed on dead insects and other arthropods that become trapped in naturally occurring petroleum pools, making this the only known insect species that develops in crude oil, a substance which is normally highly toxic to insects. Description Adults are about 5 mm long, with black bodies, except for lighter cheeks. The halteres are yellowish, with white knobs. The densely hairy eyes are nearest at the middle of the face. The third joint of the antennae is slightly longer than the second, the spine of the latter not reaching beyond the apex of the antennae. The hyaline wings are tinged with gray on nearly the entire costal half, except sometimes having a spot toward the apex of the submarginal cell. The apex of the second vein is nearly twice as far from the first as from the apex of the third vein. Biology While the larvae normally swim slowly ...

Daniel William Coquillett
Daniel William Coquillett (23 January 1856 – 7 July 1911) was an American entomologist who specialised in flies Flies are insects of the Order (biology), order Diptera, the name being derived from the Ancient Greek, Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwin .... He wrote a revision of the dipterous family Therevidae and many other scientific papers in which he described many new species and genus (biology), genera of flies. Coquillett was also the first to attempt fumigation with hydrocyanic acid as a means for controlling citrus scale insects. He experimented in the William Wolfskill, Wolfskill orange groves where he was supported by the foreman and later quarantine entomologist Alexander Craw in 1888–89.

Turpentine
Turpentine (which is also called spirit of turpentine, oil of turpentine, terebenthine, terebenthene, terebinthine and, colloquially, turps) is a fluid obtainable by the distillation of resin harvested from living trees, mainly pines. Principally used as a specialized solvent, it is also a source of material for Organic synthesis, organic syntheses. Turpentine is composed of terpenes, primarily the monoterpenes alpha-Pinene, alpha- and beta-Pinene, beta-pinene, with lesser amounts of carene, camphene, limonene, and terpinolene.Kent, James A. ''Riegel's Handbook of Industrial Chemistry'' (Eighth Edition) Van Nostrand Reinhold Company (1983) p.569 Nowadays, turpentine is rarely the product of distillation of pine resin, but is a byproduct of pulping. Pulping is achieved by two processes, the Kraft process and the sulfite process. The turpentines obtained from these two processes differ in their chemical compositions. The sulfite process gives a product that is rich in cymene, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of California
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 becomi ...

Diptera Of North America
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing more than 150,000 species including horse-flies, crane flies, hoverflies, mosquitoes and others. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great manoeuvrability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the larval food-source and the larvae, which lack true limb ...

Ephydridae
Ephydridae (shore flies, sometimes brine flies) is a family of insects in the order Fly, Diptera. Shore flies are tiny flies that can be found near seashores or at smaller inland waters, such as ponds. About 2,000 species have been described worldwide, including Ochthera. The Helaeomyia petrolei, petroleum fly, ''Helaeomyia petrolei'', is the only known insect whose larvae live in naturally occurring Petroleum, crude petroleum. Another notable species is ''Ephydra hians'' which lives in vast number at Mono Lake. Description The flies are minute to small (0.9 to 7.0 mm), with black or gray colorations. Wings are sometimes patterned. Costa with two interruptions are present in first section, near the humeral cross-vein and again near the end of vein 1. The second basal cell is not separated from the discal cell. Arista are bare or with hairs on the upper side (plumose on the upper side). The mouth opening is very large in some species. The ratio of vertical diameter of ey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eufriesea Purpurata
''Eufriesea purpurata'' is a species of Eusociality, eusocial Euglossini, orchid bee common in northeastern South America, particularly in the Amazon basin. It is an important pollinator of various wild plants, and it is noted for its attraction to various synthetic compounds used by humans, including some Insecticide, insecticides. In the late 1970s, males of the species pestered an Indigenous peoples in Brazil, indigenous Amazonian community whose palm-leaf houses had been sprayed by the government with DDT, which the bees found attractive. Morphology ''Eufriesea purpurata'' has a bright green metallic-colored head with red-orange highlights, a short tongue (5–6 mm), an adult body length of 14–17 mm, and an average body weight of 50 mg. Its thorax is most often purple, but can also be reddish, yellow, or green. Natural ecology Like other euglossine bees, ''E. purpurata'' males collect volatile floral scents, possibly for courtship purposes. Adolf Ducke ...

La Brea Tar Pits
La Brea Tar Pits comprise an active Paleontological site, paleontological research site in urban Los Angeles. Hancock Park was formed around a group of tar pits where natural Bitumen, asphalt (also called asphaltum, bitumen, or pitch; ''brea'' in Spanish) has seeped up from the ground for tens of thousands of years. Over many centuries, the bones of trapped animals have been preserved. The George C. Page Museum is dedicated to researching the tar pits and displaying specimens from the animals that died there. "La Brea Tar Pits" is a registered National Natural Landmark. Formation Tar pits are composed of Heavy crude oil, heavy oil fractions, called gilsonite, which seep from the earth as oil. Crude oil seeps up along the 6th Street Fault from the Salt Lake Oil Field, which underlies much of the Fairfax District north of Hancock Park. The oil reaches the surface and forms pools, becoming asphalt as the lighter fractions of the petroleum biodegrade or evaporate. The asphalt the ...

Transactions Of The Entomological Society Of London
The Royal Entomological Society is a learned society devoted to the study of insects. It aims to disseminate information about insects and to improve communication between entomologists. The society was founded in 1833 as the Entomological Society of London. It had many antecedents beginning as the Society of Entomologists of London. History The foundation of the society began with a meeting of "gentlemen and friends of entomological science", held on 3 May 1833 in the British Museum convened by Nicholas Aylward Vigors with the presidency of John George Children. Those present were the Reverend Frederick William Hope, Cardale Babington, William Yarrell, John Edward Gray, James Francis Stephens, Thomas Horsfield, George Thomas Rudd and George Robert Gray. Letters of Adrian Hardy Haworth, George Bennett and John Curtis were read where they expressed their regrets to be unable to attend the meeting.
