Ithomeis Eulema
''Ithomeis'' is a genus in the butterfly family Riodinidae present only in the Neotropical realm. Species *''Ithomeis aurantiaca'' Bates, 1862 present in Guyana, Brazil, Colombia, Venezuela, Ecuador and Peru *'' Ithomeis eulema'' Hewitson, 1870 present in Costa Rica, Panama, Venezuela and Colombia Biology Both species are mimics. The pattern of black, orange, and large translucent areas found in ''Ithomeis'' is shared by toxic genera from the Ithomiinae (examples are '' Ithomia'' and ''Oleria'') and a number of toxic Arctiidae. The pattern is also shared with several other Riodinidae genera (examples are ''Stalachtis'', ''Ithomiola'', and '' Brachyglenis''), which may be part of mimicry rings. ''I. aurantiaca'' has several subspecies; some are very different in appearance and were formerly regarded as full species. '' I. a. satellites'' and '' I. a. astrea'' closely resemble species of '' Heliconius''. Other subspecies include '' I. a. mimica'' and ''I a. stalachtina'', whic ...

Hyaline
A hyaline substance is one with a glassy appearance. The word is derived from el, ὑάλινος, translit=hyálinos, lit=transparent, and el, ὕαλος, translit=hýalos, lit=crystal, glass, label=none. Histopathology Hyaline cartilage is named after its glassy appearance on fresh gross pathology. On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus Diabetes, also known as diabetes mellitus, is a group of metabolic disorders characterized by a high blood sugar level (hyperglycemia) over a prolonged period of time. Symptoms often include frequent urination, increased thirst and increased ... and in association with some drugs (e.g. calcineurin inhibitors) ...

Heliconius
''Heliconius'' comprises a colorful and widespread genus of brush-footed butterflies commonly known as the longwings or heliconians. This genus is distributed throughout the tropical and subtropical regions of the New World, from South America as far north as the southern United States. The larvae of these butterflies eat passion flower vines (Passifloraceae). Adults exhibit bright wing color patterns which signal their distastefulness to potential predators. Brought to the forefront of scientific attention by Victorian naturalists, these butterflies exhibit a striking diversity and mimicry, both amongst themselves and with species in other groups of butterflies and moths. The study of ''Heliconius'' and other groups of mimetic butterflies allowed the English naturalist Henry Walter Bates, following his return from Brazil in 1859, to lend support to Charles Darwin, who had found similar diversity amongst the Galápagos finches. Model for evolutionary study ''Heliconius'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
