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 ...

Nymphalidae
The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings. Nomenclature Rafinesque i ...

Amazon Rainforest
The Amazon rainforest, also called the Amazon jungle or Amazonia, is a Tropical and subtropical moist broadleaf forests, moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses , of which are covered by the rainforest. This region includes territory belonging to nine nations and 3,344 Indigenous territory (Brazil), indigenous territories. The majority of the forest, 60%, is in Amazônia Legal, Brazil, followed by Peruvian Amazonia, Peru with 13%, Amazon natural region, Colombia with 10%, and with minor amounts in Bolivia, Ecuador, French Guiana, Guyana, Suriname, and Venezuela. Four nations have "Amazonas (other), Amazonas" as the name of one of their first-level administrative regions, and France uses the name "Guiana Amazonian Park" for French Guiana's protected rainforest area. The Amazon represents over half of the total area of remaining rainforests on Earth, and comprises the largest a ...

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically 'extent' , is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is the distance between the length from the end of an individual's arm (measured at the fingertips) to the individual's fingertips on the other arm when raised parallel to the ground at shoulder height. Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, regardless of wing shape or sweep. Implications for aircraft design and animal evolution The lift from wings is proportional to their area, so the h ...

Musa (genus)
''Musa'' is one of three Genus, genera in the family Musaceae. The genus includes 83 species of flowering plants producing edible bananas and Cooking banana, plantains, and fiber (abacá), used to make paper and cloth. Though they grow as high as trees, banana and plantain plants are not woody and their apparent "Plant stem, stem" is made up of the bases of the huge leaf Petiole (botany), stalks. Thus, they are technically gigantic herbaceous plants. Description Banana plants are among the largest extant herbaceous plants, some reaching up to in height or in the case of ''Musa ingens''. The large herb is composed of a modified underground stem (rhizome), a false trunk or pseudostem formed by the basal parts of tightly rolled leaves, a network of roots, and a large flower spike. A single leaf is divided into a leaf sheath, a contracted part called a Petiole (botany), petiole, and a terminal leaf blade. The false trunk is an aggregation of leaf sheaths; only when the plant is r ...

Heliconia
''Heliconia'' is a genus of flowering plants in the monotypic family Heliconiaceae. Most of the 194 known species are native to the tropical Americas, but a few are indigenous to certain islands of the western Pacific and Maluku (province), Maluku in Indonesia. Many species of ''Heliconia'' are found in the tropical forests of these regions. Most species are listed as either vulnerable or data deficient by the IUCN Red List of threatened species. Several species are widely cultivated as ornamentals, and a few are naturalized in Florida, Gambia, and Thailand. Common names for the genus include lobster-claws, toucan beak, wild plantain, or false bird-of-paradise; the last term refers to their close similarity to the Strelitzia, bird-of-paradise flowers in the ''Strelitzia'' genus. Collectively, these plants are also simply referred to as "heliconias". ''Heliconia'' originated in the Late Eocene (39 Ma) and are the oldest known clade of hummingbird-pollinated plants.

La Paz Waterfall, Costa Rica
La Paz (Spanish: "the peace") is a waterfall in central Costa Rica. In Spanish, it is known as ''Catarata de La Paz''. It is north of Alajuela, between Vara Blanca and Cinchona. The waterfall is located immediately alongside Route 126. The River La Paz forms the waterfall after traversing of volcanic terrain, and then continues through the rainforest of the eastern side of Poás Volcano. A short path leads behind the waterfall, where a small shrine had been located. Upstream from the waterfall is La Paz Waterfall Gardens, a hotel and park, where visitors can observe many different species of local wildlife. The waterfall and surrounding area were severely damaged in the 6.1 magnitude earthquake of January 8, 2009. Landslides damaged the road that runs alongside the waterfall, but has since been fixed and offers a roadside stop for photos and souvenirs.

Taxa Named By Cajetan Von Felder
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ...
