Kermes (genus)
''Kermes'' is a genus of gall-like scale insects in the family Kermesidae. They feed on the sap of oaks; the females produce a red dye, also called " kermes", that is the source of natural crimson. The word "kermes" is derived from Turkish ''qirmiz'' or ''kirmizi'' ( قرمز), "crimson" (both the colour and the dyestuff), itself deriving from Persian *کرمست (*kermest) via Proto-Indo-Iranian *kŕ̥miš, from Proto-Indo-European *kʷŕ̥mis (“worm”). The first instars are called "crawlers". They are less than long, salmon-colored, and wingless with well-developed legs. As adults, they demonstrate significant sexual dimorphism. Males are gnat-like with fragile wings, while females are bulbous with reduced legs and antennas, and are easily mistaken for buds or gall Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants. Plant galls are abnormal outgrowths of plant tis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sexual Dimorphism
Sexual dimorphism is the condition where sexes of the same species exhibit different Morphology (biology), morphological characteristics, including characteristics not directly involved in reproduction. The condition occurs in most dioecy, dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits. Male-male reproductive competition has evolved a diverse array of sexually dimorphic traits. Aggressive utility traits such as "battle" teeth and blunt heads reinforced as battering rams are used as weapons in aggressive interactions between rivals. Passive displays such as ornamental feathering or song-calling have also evolved mainly through sexual selection. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', when both biological sexes are phenotype, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls can be such highly organized structures that their cause can be determined without the actual agent being identified. This applies particularly to insect and mite plant galls. The study of plant galls is known as cecidology. Anatomy Shape and size Galls develop on various plant organs, providing nutrition and shelter to inducing insects. Galls display vast variation in morphology, size, and wall composition. The size of insect galls can range significantly, from approximately two inches in diameter to less than one-sixteenth of an inch. Some galls are so small that they are merely slightly thick ...

Gnat
GNAT is a free-software compiler for the Ada programming language which forms part of the GNU Compiler Collection (GCC). It supports all versions of the language, i.e. Ada 2012, Ada 2005, Ada 95 and Ada 83. Originally its name was an acronym that stood for ''GNU NYU Ada Translator'', but that name no longer applies. The front-end and run-time are written in Ada. History The GNAT project started in 1992 when the United States Air Force awarded New York University (NYU) a contract to build a free compiler for Ada to help with the Ada 9X standardization process. The 3-million-dollar contract required the use of the GNU GPL for all development, and assigned the copyright to the Free Software Foundation. The first official validation of GNAT occurred in 1995. In 1994 and 1996, the original authors of GNAT founded two sister companies, Ada Core Technologies in New York City and ACT-Europe (later AdaCore SAS) in Paris, to provide continuing development ...

Instar
An instar (, from the Latin '' īnstar'' 'form, likeness') is a developmental stage of arthropods, such as insects, which occurs 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 ny ...

Crimson
Crimson is a rich, deep red color, inclining to purple. It originally meant the color of the kermes dye produced from a scale insect, '' Kermes vermilio'', but the name is now sometimes also used as a generic term for slightly bluish-red colors that are between red and rose. It is the national color of Nepal. History Crimson (NR4) is produced using the dried bodies of a scale insect, ''Kermes'', which were gathered commercially in Mediterranean countries, where they live on the kermes oak, and sold throughout Europe. Kermes dyes have been found in burial wrappings in Anglo-Scandinavian York. They fell out of use with the introduction of cochineal, also made from scale insects, because although the dyes were comparable in quality and color intensity, ten to twelve times as much kermes is needed to produce the same effect as cochineal. Carmine is a slightly different shade of red, extracted from a different insect (female cochineal), although these denominations are somet ...
