Baron Cajetan Von Felder
Baron Cajetan von Felder (; 19 September 1814 – 30 November 1894) was an Austrian lawyer, entomologist and Liberalism in Austria, liberal politician. He served as List of mayors of Vienna, 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 (Germany), ''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 Revolutions of 1848 in the Austrian Empire, March Revo ...

Butterfly
Butterflies are winged insects from the lepidopteran superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage life cycle, and like other holometabolous 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, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take s ...

Hesperiidae
Skippers are a group of butterflies placed in the family Hesperiidae within the order Lepidoptera (moths and butterflies). They were previously placed in a separate superfamily, Hesperioidea, but have since been placed 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 lack 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. The third and rather small butterfly superfamily is the moth ... [...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 ...° or in radians ... . 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, where the equivalences follow from well-known alge ...

Tagiadini
The Tagiadini are a tribe (biology), tribe of skipper butterfly, butterflies in the family Skipper (butterfly), Hesperiidae. Many of its genera were of uncertain relationships for long, and delimitation of the Tagiadini versus the Celaenorrhinini 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 * ''Abaratha'' * ''Ctenoptilum'' * ''Leucochitonea'' * ''Netrobalane'' – buff-tipped skipper * ''Semperium'' * ''Tagiades'' – water flats, snow flats Other genera * ''Abraximorpha'' * ''Albiphasma'' * ''Calleagris'' – scarce flats * ''Capila'' (formerly often placed in Celaenorrhinini) * ''Coladenia'' * ''Daimio ...
