Ennominae
Ennominae is the largest subfamily of the geometer moth family (Geometridae) with some 9,700 described species in 1,100 genera. They are usually a fairly small moths, though some (such as the peppered moth) grow to be considerably large. This subfamily has a global distribution. It includes some species that are notorious defoliating pests. The subfamily was first described by Philogène Auguste Joseph Duponchel in 1845. The status of several tribes is debated.For example, the Boarmiini are sometimes massively expanded to include the Bistonini, Bupalini, Erannini, Gnophini, Melanolophini, Phaseliini and Theriini. The Nacophorini and perhaps the Campaeini might need to be merged with the Lithinini, and all three might warrant merging into the Ennomini.The group sometimes separated as Cassymini is tentatively included in the Abraxini here. The Alsophilinae, usually treated as a small subfamily in their own right, might simply be a specialized lineage of Boarmiini. Se ...

Geometer Moth
The geometer moths are moths belonging to the family Geometridae of the insect order Lepidoptera, the moths and butterflies. Their scientific name derives from the Ancient Greek ''geo'' γεω (derivative form of or "the earth"), and ''metron'' "measure" in reference to the way their larvae, or inchworms, appear to measure the earth as they move along in a looping fashion. A very large family, it has around 23,000 species of moths described, and over 1400 species from six subfamilies indigenous to North America alone. A well-known member is the peppered moth, ''Biston betularia'', which has been subject of numerous studies in population genetics. Several other geometer moths are notorious pests. Adults Many geometrids have slender abdomens and broad wings which are usually held flat with the hindwings visible. As such, they appear rather butterfly-like, but in most respects they are typical moths; the majority fly at night, they possess a frenulum to link the wings, and the ...

Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boarmiini
The Boarmiini (also often called ''Cleorini'') are a large tribe of geometer moths in the Ennominae subfamily. Description and systematics This family is sometimes massively expanded, with the closely related Bistonini, Bupalini, Erannini, Gnophini, Melanolophini, Phaseliini and Theriini all merged into it. The eggs of all these geometer moths have the chorion cells characteristically arranged in longitudinal rows. The eggs of the Boarmiini in the narrow sense usually have a typical slender and narrow shape, with a soft chorion consisting of heavy-walled but unridged polygonal cells. However, in ''Cleora'' for example, the eggs approach the wide-walled shape found in many Bistonini. Adding further to the uncertainty is the fact that the Alsophilinae, usually treated as a small subfamily in their own right, might be a specialized lineage of Boarmiini; though their caterpillars are quite different, their pupae have a peculiar T-shaped cremaster which very much resembles that o ...

Baltic Amber
The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014, 400 tonnes in 2015. "Baltic amber" was formerly thought to include amber from the Bitterfeld Lignite, brown coal mines in Saxony (Eastern Germany). Bitterfeld amber was previously believed to be only 20–22 million years old (Miocene), but a comparison of the animal inclusions in 2003 suggested that it was possibly Baltic amber that was redeposited in a Miocene deposit. Further study of insect taxa in the ambers has shown Bitterfeld amber to be from the same forest as the Baltic amber forest, but separately deposited f ...

Newsweek
''Newsweek'' is an American weekly online news magazine co-owned 50 percent each by Dev Pragad, its president and CEO, and Johnathan Davis (businessman), Johnathan Davis, who has no operational role at ''Newsweek''. Founded as a weekly print magazine in 1933, it was widely distributed during the 20th century, and had many notable editors-in-chief. The magazine was acquired by The Washington Post Company in 1961, and remained under its ownership until 2010. Revenue declines prompted The Washington Post Company to sell it, in August 2010, to the audio pioneer Sidney Harman for a purchase price of one dollar and an assumption of the magazine's liabilities. Later that year, ''Newsweek'' merged with the news and opinion website ''The Daily Beast'', forming The Newsweek Daily Beast Company. ''Newsweek'' was jointly owned by the estate of Harman and the diversified American media and Internet company IAC (company), IAC. ''Newsweek'' continued to experience financial difficulties, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lutetian
The Lutetian is, in the geologic timescale, a stage or age in the Eocene. It spans the time between . The Lutetian is preceded by the Ypresian and is followed by the Bartonian. Together with the Bartonian it is sometimes referred to as the Middle Eocene Subepoch. Stratigraphic definition The Lutetian was named after Lutetia, the Latin name for the city of Paris. The Lutetian Stage was introduced in scientific literature by French geologist Albert de Lapparent in 1883 and revised by A. Blondeau in 1981. The base of the Lutetian Stage is at the first appearance of the nanofossil ''Blackites inflatus'', according to an official reference profile (GSSP) established in 2011. Of two candidates located in Spain, the Gorrondatxe section was chosen.See thwebsite of Eustoquio Molinafor these candidates. The top of the Lutetian (the base of the Bartonian) is at the first appearance of calcareous nanoplankton species ''Reticulofenestra reticulata''. The Lutetian overlaps with the Geisel ...

Epoch (geology)
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define gl ...

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...
