Large Chequered Skipper
The large chequered skipper (''Heteropterus morpheus'') is a butterfly of the family Hesperiidae. It is the single member of the monotypic genus ''Heteropterus''. The species can be found in isolated populations in Europe and east across the Palearctic to Central Asia and Korea. It is endangered in the Netherlands. The length of the forewings is 15–18 mm. The butterfly is on the wing from June to August, depending on the location. The larvae feed on ''Eriophorum'', ''Poa annua'', ''Calamagrostis canescens'', ''Brachypodium'' and ''Molinia'' species (including ''Molinia coerulea''). As can be seen, the butterfly has a very distinctive and attractive underside but a drab upperside (which is rarely seen, as it usually settles with wings closed). This butterfly is very similar to the Chequered skipper, but they have their own attributes that allow them to be distinguished. The flight is just as distinctive and indeed provides immediate identification of the species: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
André Marie Constant Duméril
André Marie Constant Duméril (1 January 1774 – 14 August 1860) was a French zoologist. He was professor of anatomy at the Muséum national d'histoire naturelle from 1801 to 1812, when he became professor of herpetology and ichthyology. His son Auguste Duméril was also a zoologist. Life André Marie Constant Duméril was born on 1 January 1774 in Amiens and died on 14 August 1860 in Paris. He became a doctor at a young age, obtaining, at 19 years, the ''prévot'' of anatomy at the medical school of Rouen. In 1800, he left for Paris and collaborated in the drafting of the comparative anatomy lessons of Georges Cuvier. He replaced Cuvier at the Central School of the Panthéon and had, as his colleague, Alexandre Brongniart. In 1801, he gave courses to the medical school of Paris. Under the ''Restauration'', he was elected a member of the Académie des Sciences (French Academy of Sciences) and after 1803 succeeded Lacépède, who was occupied by his political offic ...

Poa Annua
''Poa annua'', or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass may have originated as a hybrid between ''Poa supina'' and '' Poa infirma''. Description It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm (6-10 in.) high. It is slightly flattened, due to being folded rather than rolled. The panicle is open and triangular shaped, 5 to 7.5 cm (2 to 3 in.) long. The spikelets are stalked, awnless, 1 to 2 cm (3/8 to 3/4 in.) long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe. They are soft and drooping. Long sheaths clasp the stem. The leaves are smooth above and below, with fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterflies Described In 1771
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, ...

Consortium For The Barcode Of Life
The Consortium for the Barcode of Life (CBOL) was an international initiative dedicated to supporting the development of DNA barcoding as a global standard for species identification. CBOL's Secretariat Office is hosted by the National Museum of Natural History, Smithsonian Institution, in Washington, DC. Barcoding was proposed in 2003 by Prof. Paul Hebert of the University of Guelph in Ontario as a way of distinguishing and identifying species with a short standardized gene sequence. Hebert proposed the 658 bases of the Folmer region of the mitochondrial gene cytochrome-C oxidase-1 as the standard barcode region. Hebert is the Director of the Biodiversity Institute of Ontario, the Canadian Centre for DNA Barcoding, and the International Barcode of Life Project (iBOL), all headquartered at the University of Guelph. The Barcode of Life Data Systems (BOLD) is also located at the University of Guelph. CBOL was created in May 2004 with support of the Alfred P. Sloan Foundation, f ...

Carterocephalus Palaemon
''Carterocephalus palaemon'', the chequered skipper or arctic skipper, not to be confused with the large chequered skipper, is a small woodland butterfly in the family Hesperiidae. This butterfly can live in grasslands. The upperside of the butterfly is brown with orange spots and on its underside the chequered skipper is orange with brown spots. Chequered skippers are found in Great Britain and other European regions, but seen locally in Japan and in North America. The size of the chequered skipper ranges from 19 to 32 mm with females being larger. In the 1970s, the chequered skipper went extinct in England due to the new management of the woodlands. Description This butterfly has a wingspan of 29 to 31 mm. The uppersides of chequered skippers are dark brown with orange scales at the base of the wings and golden spots, giving it its English name of chequered skipper. The basic pattern on the underside is similar but the forewings are orange with dark spots, and the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brachypodium
''Brachypodium'' is a genus of plants in the grass family, widespread across much of Africa, Eurasia, and Latin America. The genus is classified in its own tribe Brachypodieae. Flimsy upright stems form tussocks. Flowers appear in compact spike-like racemes with 5-25 flowers on each short-stalked spikelet in summer. Leaves are flat or curved. According to an October 18, 2010 issue of "Nature Online" Laura Longo, an archeologist at University of Siena in Italy found evidence of ''Brachypodium'' and cattail ('' Typha'' spp.) residues on prehistoric human grinding tools dated 28,000 years ago from Bilancino in central Italy. A related article authored by Anna Revedin, Biancamaria Aranguren, Roberto Becattini, Laura Longo, Emanuele Marconi, Marta Mariotti Lippi, Natalia Skakun, Andrey Sinitsyn, Elena Spiridonova, and Jiří Svoboda, was contemporaneously published in the Proceedings of the National Academy of Sciences of the United States of America and clarifies that the grain r ...

Eriophorum
''Eriophorum'' (cottongrass, cotton-grass or cottonsedge) is a genus of flowering plants in the family Cyperaceae, the sedge family. They are found throughout the arctic, subarctic, and temperate portions of the Northern Hemisphere in acid bog habitats, being particularly abundant in Arctic tundra regions.Flora Europaea''Eriophorum''/ref> They are herbaceous perennial plants with slender, grass-like leaves. The seed heads are covered in a fluffy mass of cotton-like fibers which are carried on the wind to aid dispersal. The cotton grass also maintains a height of 12 inches and around 2 inches in water. In cold Arctic regions, these masses of translucent fibres also serve as 'down' – increasing the temperature of the reproductive organs during the Arctic summer by trapping solar radiation. Paper and the wicks of candles have been made of its fiber, and pillows stuffed with the same material. The leaves were formerly used in treating diarrhea, and the spongy pith of the stem ...
