Melitaea Telona
''Melitaea ornata'', the eastern knapweed fritillary, is a butterfly in the family Nymphalidae. The species rank of ''Melitaea ornata'' (type locality Guberlya, Russia) was only very recently recognised by two research groups independently (Russell et al., 2005; Varga et al., 2005). They realized that there was an unrecognised species in Europe under the name of '' M. phoebe''. The separation of this cryptic species was based on larval morphology from the fourth instar onwards. ''M. phoebe'' larvae have a black head capsule while the larvae of this recently recognised Ponto-Mediterranean species have a brick-red head capsule (Russell et al., 2007). The separation of the two taxa was also supported by the results of enzyme electrophoresis study (Pecsenye et al., 2007). Based on these observations, the name ''M. telona'' Fruhstorfer (type locality: Jerusalem, Israel) was taken into use for this species. In a recent molecular study, the ''M. phoebe'' group forms a monophyletic clade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hugo Theodor Christoph
Hugo Theodor Christoph (16 April 1831 – 5 November 1894) was a German and Russian entomologist. Born in Herrnhut in Saxony, Hugo Theodor Christoph moved to Russia in 1858. He became a member of the Russian Entomological Society in 1861. From 1880, he was curator of the Lepidoptera collection of Grand Duke Nicholas Mikhailovich of Russia. His own collection was sold to Thomas de Grey, 6th Baron Walsingham, a member of the Royal Entomological Society, and it is now in the Natural History Museum A natural history museum or museum of natural history is a scientific institution with natural history collections that include current and historical records of animals, plants, fungi, ecosystems, geology, paleontology, climatology, and more. ... in London.

Sensu Stricto
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: *''sensu stricto'' – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; *''sensu lato'' – "in the broad sense", abbreviation ''s.l.''; *''sensu amplo'' – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense". When appropriate, comparative and superlative adjectives may also be used to convey the meaning o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterflies Of Asia
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, it fli ...

Melitaea
''Melitaea'' is a genus of brush-footed butterflies (family Nymphalidae). They are here placed in the tribe Melitaeini of subfamily Nymphalinae; some authors elevate this tribe to subfamily rank. As delimited here, ''Melitaea'' includes the genus ''Mellicta'', making the subtribe Melitaeina monotypic (but see below). For long, it was believed that ''Mellicta'' was a junior objective synonym of ''Melitaea'', sharing the same type species (the Glanville fritillary, ''M. cinxia''). This was in error, however; the type species of ''Mellicta'' is actually the heath fritillary (''M. athalia''), making the two taxa junior subjective synonyms and thus eligible to be separated again. However, several other taxa are in fact objective synonyms (or at least have type specimens belonging to the same biological species) of ''Melitaea'' and ''Mellicta'' – ''Schoenis'' and the preoccupied ''Lucina'' and ''Melinaea'' for the former, ''Athaliaeformia'' for the latter.

Centaurea
''Centaurea'' () is a genus of over 700 species of herbaceous thistle-like flowering plants in the family Asteraceae. Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich. In the western United States, yellow starthistles are an invasive species. Around the year 1850, seeds from the plant had arrived to the state of California. It is believed that those seeds came from South America. Common names Common names for this genus are centaury, centory, starthistles, knapweeds, centaureas and the more ambiguous "bluets"; a vernacular name used for these plants in parts of England is "loggerheads" (common knapweed). The ''Plectocephalus'' group – possibly a distinct genus – is known as basketflowers. "Cornflower" is used for a few species, but that term more often specifically means either '' C. cyanus'' (the annual cornflower) or ''Centaurea montana'' (the perennial c ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Oligophagy
Oligophagy refers to the eating of only a few specific foods, and to monophagy when restricted to a single food source. The term is usually associated with insect dietary behaviour.''Oligophagy'' on Dictionary.com Accessed on 9 January 2010. Organisms may exhibit narrow or specific oligophagy where the diet is restricted to a very few foods or broad oligophagy where the organism feeds on a wide variety of specific foods but none other.Huffaker & Gutierrez ''Ecological Entomology'', pg 201. , on the contrary, refers to eating a broad spectrum of foods. In the insect world it refers usually to insects that feed on plants belonging to different families. |
Taxonomical Changes In The Melitaea Phoebe Species Group
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Hans Fruhstorfer
Hans Fruhstorfer (7 March 1866, in Passau, Germany – 9 April 1922, in Munich) was a German explorer, insect trader and entomologist who specialised in Lepidoptera. He collected and described new species of exotic butterflies, especially in Adalbert Seitz's ''Macrolepidoptera of the World''. He is best known for his work on the butterflies of Java. His career began in 1888 when he spent two years in Brazil. His expedition in Brazil was financially successful and led to his becoming a professional collector. After his successful endeavor, he spent some time in Sri Lanka (then Ceylon), then in 1890 he went to Java for three years, visiting Sumatra. Between 1895 and 1896 he collected in Sulawesi, Lombok and Bali. In 1899, he went on a three-year journey to the United States, Oceania, Japan, China, Tonkin, Annam and Siam, returning via India. Following his travels, he settled in Geneva where he wrote monographs based on the specimens in his extensive private collection. Many of th ...

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...
