Theagenes Dichrous
Theagenes (), also spelled Theogenes, is a masculine given name which may refer to: People :''Ordered chronologically.'' * Theagenes of Megara, 7th century BC tyrant of Megara * Theagenes of Rhegium (), Greek literary critic * Theagenes of Thasos, 5th century BC Greek boxer * Theagenes (patrician) (), Athenian politician, Roman senator and archon * Theagenes, an Athenian who was appointed with Cleon in 425 BC to go to Pylos and investigate the truth of the tidings of the difficulties of the blockade of Sphacteria, according to Thucydides (though Cleon persuaded the people to abandon the inquiry. huc. iv. 27 It is possible that this Theagenes is the person who is mentioned by Aristophanes (Vesp. 1183), and who, the scholiast tells us, was an Acharnian (Arnold, ad Thuc. I.e.). A man of the same name is satirized also by Aristophanes (Pax, 894) for his swinish propensities. (See also Arist.

Animal
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...

Arthropod
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...

Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidoptera
Lepidoptera ( ) or lepidopterans is an order (biology), order of winged insects which includes butterflies and moths. About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, making it the second largest insect order (behind Coleoptera) with 126 family (biology), families and 46 Taxonomic rank, superfamilies, and one of the most widespread and widely recognizable insect orders in the world. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, large triangular Insect wing, wings, and a proboscis for siphoning nectars. The scales are modified, flattened "hairs", and give butterflies and moths their wide variety of colors and patterns. Almost all species have some form of membranous wings, except for a few that have reduced wings or are wingless. Mating and the laying of eggs is normally performe ...

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] |
Pyrginae
Pyrginae, commonly known as spread-winged skippers, are a subfamily of the skipper butterfly family (biology), family (Hesperiidae). The subfamily was established by Hermann Burmeister in 1878. Their delimitation and internal systematics has changed considerably in recent years with the most recent review being in 2019. It still is the second-largest subfamily of skipper butterflies, although of its over 1,000 species a considerable number are no longer in that classification. Description and distribution Spread-winged skippers bask with their wings held wide open. The wings are held closed when they are at rest. They are usually brown, black, or checkered, but some are brilliantly coloured. Some have long tailed hind wings.Daniels (2003): p.12 Males maintain territories and frequently perch on overhanging branches and tree trunks. They do not visit flowers for sustenance, but rather drink fluids from Feces, dung, carrion, and rotting fruit. A large and successful subfamily, ...

Erynnini
The Erynnini are a tribe in the skipper butterfly subfamily Pyrginae. They are a moderately diverse but quite plesiomorphic and inconspicuous group, and except for the Holarctic species of the type genus '' Erynnis'' occur only in the Neotropics.Brower (2009) Formerly, when only four tribes of Pyrginae were recognized, they were included in the Pyrgini, which at that time contained a massive number of genera. But the Pyrginae have since been reorganized to make them and their tribes monophyletic, leading most modern authors to treat the Erynnini as distinct tribe. However, the old circumscription of the Pyrgini was by and large just as correct from a phylogenetic perspective. The tribe of the Pyrgini '' sensu lato'' most closely related to the Pyrgini ''sensu stricto'' are the strikingly different Achlyodidini. As many consider it desirable to treat this lineage as a distinct tribe, the Erynnini naturally need to be considered distinct too. Genera The genera are listed here ...

Frederick DuCane Godman
Frederick DuCane Godman (15 January 1834 – 19 February 1919) was an English lepidopterist, entomology, entomologist and ornithology, ornithologist. He was one of the twenty founding members of the British Ornithologists' Union. Along with Osbert Salvin, he is remembered for studying the fauna and flora of Central America. Godman collected Iznik pottery, Iznik, Hispano-Moresque ware, Hispano-Moresque and early Iranian pottery. His collection of more than 600 pieces was donated to the British Museum through the will of his younger daughter, Catherine, who died in 1982. Early life and Cambridge years Frederick DuCane Godman was born on 15 January 1834 at Park Hatch, Godalming, Surrey, and was one of the thirteen children of Joseph Godman and Caroline Smith. Joseph Godman was a partner in the brewery firm Whitbread & Company. Frederick was sent to study at Eton College in 1844 but left three years later due to poor health and was educated at home by private tutors. At the age of ...

Osbert Salvin
Osbert Salvin (25 February 1835 – 1 June 1898) was an English natural history, naturalist, Ornithology, ornithologist, and Herpetology, herpetologist best known for co-authoring ''Biologia Centrali-Americana'' (1879–1915) with Frederick DuCane Godman. This was a 52-volume encyclopedia on the natural history of Central America. Biography Osbert Salvin was born in Finchley, north London, the second son of the architect Anthony Salvin, of Hawksfold, Sussex. He was educated at Westminster School and Trinity Hall, Cambridge, taking his degree in 1857. Shortly afterwards he accompanied his second cousin by marriage, Henry Baker Tristram, in a natural history exploration of Tunisia and eastern Algeria. Their account of this trip was published in ''Ibis (journal), The Ibis'' in 1859 and 1860. In the autumn of 1857, he made the first of several visits to Guatemala, returning there with Frederick DuCane Godman in 1861. It was during this journey that the ''Biologia Centrali-Americana ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
