Formiscurra Indicus
''Formiscurra indicus'' is a species of planthopper in the family Caliscelidae found in southern India. A related species, '' Formiscurra atlas'' occurs in southwestern Ethiopia. Like others of its family they have short wings, suck plant sap and escape by leaping. The species shows great sexual dimorphism. The male of this half centimeter-long insect has an enlarged lobe in front of its head, the frons or metope, giving it an ant-like appearance. Females do not have such an enlarged structure but have a slightly long snout and differ slightly in body shape. The species is found mainly on low vegetation in open scrub and grass habitats. Discovery This species was described in 2011 on the basis of specimens collected from around southern India from as far back as 1978. The holotype was collected in the campus of the University of Agricultural Sciences at Bangalore in the state of Karnataka in India. Other specimens have been collected from a widely separated locations in souther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Insects Described In 2011
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formiscurra Dorsal
''Formiscurra'' is a genus of planthopper in the family Caliscelidae with two species: ''Formiscurra indicus'' of southern India and ''Formiscurra atlas'' from southwestern Ethiopia. Like others of its family they have short wings, suck plant sap and escape by leaping. The species shows great sexual dimorphism Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most an .... The males of this half centimeter-long insect have an enlarged lobe in front of its head, the frons or metope, giving it an ant-like appearance. Females do not have such an enlarged structure but have a slightly long snout and differ slightly in body shape. The species is found mainly on low vegetation in open scrub and grass habitats. It has been suggested, based on the Afro-Indian distribution, that the ancestral species o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Müllerian Mimicry
Müllerian mimicry is a natural phenomenon in which two or more well-defended species, often foul-tasting and sharing common predators, have come to mimicry, mimic each other's honest signal, honest aposematism, warning signals, to their mutualism (biology), mutual benefit. The benefit to Müllerian mimics is that predators only need one unpleasant encounter with one member of a set of Müllerian mimics, and thereafter avoid all similar coloration, whether or not it belongs to the same species as the initial encounter. It is named after the German naturalist Fritz Müller, who first proposed the concept in 1878, supporting his theory with the first mathematical model of frequency-dependent selection, one of the first such models anywhere in biology. Müllerian mimicry was first identified in tropical butterfly, butterflies that shared colourful wing patterns, but it is found in many groups of insects such as bumblebees, and other animals including Ranitomeya, poison frogs and co ...

Buprestidae
Buprestidae is a family of beetles known as jewel beetles or metallic wood-boring beetles because of their glossy iridescent colors. Larvae of this family are known as flatheaded borers. The family is among the largest of the beetles, with some 15,500 species known in 775 genera. In addition, almost 100 fossil species have been described. The larger and more spectacularly colored jewel beetles are highly prized by insect collectors. The elytra of some Buprestidae species have been traditionally used in beetlewing jewellery and decoration in certain countries in Asia, like India, Thailand and Japan. Description and ecology Shape is generally cylindrical or elongate to ovoid, with lengths ranging from , although most species are under . '' Catoxantha'', '' Chrysaspis'', '' Euchroma'' and '' Megaloxantha'' contain the largest species. A variety of bright colors are known, often in complicated patterns. The iridescence common to these beetles is not due to pigments in the exosk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batesian Mimicry
Batesian mimicry is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both. It is named after the English naturalist Henry Walter Bates, after his work on butterflies in the rainforests of Brazil. Batesian mimicry is the most commonly known and widely studied of mimicry complexes, such that the word mimicry is often treated as synonymous with Batesian mimicry. There are many other forms however, some very similar in principle, others far separated. It is often contrasted with Müllerian mimicry, a form of mutually beneficial convergence between two or more harmful species. However, because the mimic may have a degree of protection itself, the distinction is not absolute. It can also be contrasted with functionally different forms of mimicry. Perhaps the sharpest contrast here is with aggressive mimicry where a predator or parasite mimics a harmless species, avoiding detection and improving it ...

Myrmecomorphic
Ant mimicry or myrmecomorphy is mimicry of ants by other organisms. Ants are abundant all over the world, and potential predators that rely on vision to identify their prey, such as birds and wasps, normally avoid them, because they are either unpalatable or aggressive. Spiders are the most common ant mimics. Additionally, some arthropods mimic ants to escape predation ( protective mimicry), while others mimic ants anatomically and behaviourally to hunt ants in aggressive mimicry. Ant mimicry has existed almost as long as ants themselves; the earliest ant mimics in the fossil record appear in the mid Cretaceous alongside the earliest ants. Indeed one of the earliest, '' Burmomyrma'', was initially classified as an ant. In Wasmannian mimicry, mimic and model live commensally together; in the case of ants, the model is an inquiline in the ants' nest. Wasmannian mimics may also be Batesian or aggressive mimics. To simulate ants' powerful defences, mimics may imitate ants chemica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Populonia (planthopper)
Populonia or Populonia Alta ( Etruscan: ''Pupluna'', ''Pufluna'' or ''Fufluna'', all pronounced ''Fufluna''; Latin: ''Populonium'', ''Populonia'', or ''Populonii'') today is a of the ''comune'' of Piombino (Tuscany, central Italy). As of 2009 its population was 17. It is one of I Borghi più belli d'Italia ("The most beautiful villages of Italy"). Populonia is especially noteworthy for its Etruscan remains, including one of the main necropolis in Italy, discovered by Isidoro Falchi.

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree. History The theoretical ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four ...
