Eogeometer
''Eogeometer'' is a prehistoric genus of Ennomine geometer moths in the tribe Boarmiini. The type and only species is ''Eogeometer vadens'', the specimen of which measured about , and was estimated to be 44 million years old, dating back to Eocene epoch. Both the genus and species were described by Thilo C. Fischer, Artur Michalski and Axel Hausmann in 2019 as the first geometrid caterpillar in Baltic amber Baltic amber or succinite is amber from the Baltic region, home of its largest known deposits. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that this forested region provided the re ....

Ennominae
Ennominae is the largest subfamily of the geometer moth family (Geometridae), with some 9,700 described species in 1,100 genera. Most species are fairly small, 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. P ...

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 (derivative form of or "the earth"), and "measure" in reference to the way their larvae, or inchworms, appear to measure the earth as they move along in a looping fashion. Geometridae is a very large family, containing around 23,000 described species; over 1400 species from six subfamilies are indigenous to North America alone. A well-known member is the peppered moth, ''Biston betularia'', which has been the subject of numerous studies in population genetics. Several other geometer moths are notorious pests. Caterpillars The name "Geometridae" ultimately derives from Latin ' from Greek ("geometer", "earth-measurer"). This refers to the means of locomotion of the larvae or caterpillars, which lack the full complement of prolegs seen in other caterpillars, with only two or three pairs at the posteri ...

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 ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boarmiini
The Boarmiini (also often called ''Cleorini'') are a large tribe (biology), 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 Chrysalis#Chrysalis, cremaster ...

Baltic Amber
Baltic amber or succinite is amber from the Baltic region, home of its largest known deposits. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that this forested region provided the resin for 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 and 400 tonnes in 2015. Baltic amber is also found in Poland, as well as the Baltic states. Bitterfeld amber from the brown coal mines near Bitterfeld in Germany was previously thought to be redeposited Baltic amber, but is now known to be chemically distinct, though like with Ukrainian Rovno amber, it is thought to have been deposited around the same time as Baltic amber. Because Baltic amber contains from 3 to 8% succinic acid, it is also termed succinite. Geologic context ''In situ'' Balt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutetian
The Lutetian is, in the geologic timescale, a stage (stratigraphy), stage or age (geology), 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 language, 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.

Monotypic Prehistoric Insect Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Eocene Insects Of Europe
The Eocene ( ) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period in the modern Cenozoic 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.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." 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 13C in the atmosphere was exceptionally low in com ...

Newsweek
''Newsweek'' is an American weekly news magazine based in New York City. Founded as a weekly print magazine in 1933, it was widely distributed during the 20th century and has had many notable editors-in-chief. It is currently co-owned by Dev Pragad, the president and chief executive officer (CEO), and Johnathan Davis, who sits on the board; each owns 50% of the company. In August 2010, revenue decline prompted Graham Holdings, the Washington Post Company to sell ''Newsweek'' to the audio pioneer Sidney Harman for one US 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, later called ''NewsBeast''. ''Newsweek'' was jointly owned by the estate of Harman and the company IAC (company), IAC. ''Newsweek'' continued to experience financial difficulties, leading to the suspension of print publication at the end of 2012. In 2013, IBT Media acquired ...
