Baron Cajetan Von Felder
Baron Cajetan von Felder (german: link=no, Cajetan Freiherr von Felder; 19 September 1814 – 30 November 1894) was an Austrian lawyer, entomologist and liberal politician. He served as mayor of Vienna from 1868 to 1878. Life and career Felder was born in Wieden, today the fourth district of Vienna. An orphan from 1826, he attended the ''Gymnasium'' of Seitenstetten Abbey, as well as schools in Brno and Vienna, and began to study law at the University of Vienna in 1834. He completed his legal internship in Brno and articled clerk in Vienna, obtaining his doctorate in 1841. Since 1835 he had made intensive travels throughout Western and Southern Europe, mostly on foot, and studied foreign languages. From 1843 he also worked as an assistant at the Theresianum academy and as a court interpreter in Vienna, before passing the Austrian bar examination in 1848, only a few days before the outbreak of the March Revolution. In October 1848 Felder was elected to the newly established m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), 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 Holometabolism, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hesperiidae
Skippers are a family of the Lepidoptera (moths and butterflies) named the Hesperiidae. Being diurnal, they are generally called butterflies. They were previously placed in a separate superfamily, Hesperioidea; however, the most recent taxonomy places the family in the superfamily Papilionoidea, the butterflies. They are named for their quick, darting flight habits. Most have their antenna tips modified into narrow, hook-like projections. Moreover, skippers mostly have an absence of wing-coupling structure available in most moths. More than 3500 species of skippers are recognized, and they occur worldwide, but with the greatest diversity in the Neotropical regions of Central and South America.Ackery et al. (1999) Description and systematics Traditionally, the Hesperiidae were placed in a monotypic superfamily Hesperioidea, because they are morphologically distinct from other Rhopalocera (butterflies), which mostly belong to the typical butterfly superfamily Papilionoidea.

Jharkhand
Jharkhand (; ; ) is a state in eastern India. The state shares its border with the states of West Bengal to the east, Chhattisgarh to the west, Uttar Pradesh to the northwest, Bihar to the north and Odisha to the south. It has an area of . It is the 15th largest state by area, and the 14th largest by population. Hindi is the official language of the state. The city of Ranchi is its capital and Dumka its sub-capital. The state is known for its waterfalls, hills and holy places; Baidyanath Dham, Parasnath, Dewri and Rajrappa are major religious sites. The state was formed on 15 November 2000, after carving out what was previously the southern half of Bihar. Jharkhand suffers from what is sometimes termed a resource curse: it accounts for more than 40% of the mineral resources of India, but 39.1% of its population is below the poverty line and 19.6% of children under five years of age are malnourished. Jharkhand is primarily rural, with about 24% of its population living in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odisha
Odisha (English: , ), formerly Orissa ( the official name until 2011), is an Indian state located in Eastern India. It is the 8th largest state by area, and the 11th largest by population. The state has the third largest population of Scheduled Tribes in India. It neighbours the states of Jharkhand and West Bengal to the north, Chhattisgarh to the west, and Andhra Pradesh to the south. Odisha has a coastline of along the Bay of Bengal in Indian Ocean. The region is also known as Utkala and is also mentioned in India's national anthem, " Jana Gana Mana". The language of Odisha is Odia, which is one of the Classical Languages of India. The ancient kingdom of Kalinga, which was invaded by the Mauryan Emperor Ashoka (which was again won back from them by King Kharavela) in 261 BCE resulting in the Kalinga War, coincides with the borders of modern-day Odisha. The modern boundaries of Odisha were demarcated by the British Indian government when Orissa Province wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Golden Angle (Caprona Ransonnetii Potifera)
In geometry, the golden angle is the smaller of the two angles created by sectioning the circumference of a circle according to the golden ratio; that is, into two arcs such that the ratio of the length of the smaller arc to the length of the larger arc is the same as the ratio of the length of the larger arc to the full circumference of the circle. Algebraically, let ''a+b'' be the circumference of a circle, divided into a longer arc of length ''a'' and a smaller arc of length ''b'' such that : \frac = \frac The golden angle is then the angle subtended by the smaller arc of length ''b''. It measures approximately 137.5077640500378546463487 ...° or in radians 2.39996322972865332 ... . The name comes from the golden angle's connection to the golden ratio ''φ''; the exact value of the golden angle is : 360\left(1 - \frac\right) = 360(2 - \varphi) = \frac = 180(3 - \sqrt)\text or : 2\pi \left( 1 - \frac\right) = 2\pi(2 - \varphi) = \frac = \pi(3 - \sqrt)\text, wh ...

Tagiadini
The Tagiadini are a tribe in the skipper butterfly subfamily Pyrginae. Many of its genera were of uncertain relationships for long, and delimitation of the Tagiadini versus the Celaenorrhini was quite disputed at times. The species of this tribe are found in mostly tropical regions of Africa, Asia and Australia.Brower (2007) Genera Altogether, the tribe contains 27 genera. Some of these seem to form a close-knit group around the tribe's type genus ''Tagiades''. These genera are often collectively called "Tagiades group" and may form a clade: "Tagiades group" * '' Abantis'' – paradise skippers * '' Caprona'' – ragged skippers * '' Ctenoptilum'' * '' Leucochitonea'' * '' Netrobalane'' – buff-tipped skipper * '' Odontoptilum'' * ''Semperium'' * ''Tagiades'' – water flats, snow flats Other genera * '' Abraximorpha'' * ''Calleagris'' – scarce flats * '' Capila'' (formerly often in Celaenorrhini) * '' Chaetocneme'' * ''Chamunda'' * '' Coladenia'' * '' Daimi ...
