Cryptochetidae
The Cryptochetidae are a small family of tiny flies (generally 2 to 4 mm long). Some twenty to thirty species are known. Generally they are metallic blue black, stoutly built, with the head broad and high and with clear wings.McAlpine, J. F. et al (eds) Manual of Nearctic Diptera. Monographs No. 27 & No. 28 Biosystematics Research Institute, Ottawa. Ontario Research Branch. Pub: Agriculture Canada Vol 1 1981 & Vol 2 1987 Like other species in the superfamily Lonchaeoidea, the Cryptochetidae have antennae with a cleft in the second segment. Unlike practically all Schizophora however, they lack an arista, or if they do have one, it is too small to distinguish with any confidence. The family name refers to this unusual distinction; "Cryptochetidae" literally means "those with hidden bristles". The adult flies also are unusual among insects in that they have only a single pair of abdominal spiracles — this is not a serious physiological challenge in such small insects. Again i ...

Lonchaeoidea
The Lonchaeoidea are a superfamily of generally small or very small black flies with large heads. It contains two families, the Lonchaeidae (lance flies) and the Cryptochetidae. The superfamily was established by G. C. Griffiths in 1972Griffiths, G. C. Phylogenetic Classification of Diptera Cyclorrhapha. Publisher: Springer 1972. and came into general use as such. Characteristics of the Lonchaeoidea include antennae with the second segment cleft, and not more than one proclinate orbital bristle on each side. The frons Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insec ... is densely setulose.

Charles Thomas Brues
Charles Thomas Brues (June 20, 1879, Wheeling, West Virginia – July 22, 1955, Crescent City, Florida) was an American entomologist. Biography Brues studied at the University of Texas at Austin and at Columbia University. He was appointed field agent of the Bureau of Entomology, United States Department of Agriculture 1904-05, curator of invertebrate zoology at the Milwaukee Public Museum 1905-09, and then became instructor in economic entomology at Harvard University. His contributions on embryology and the habits of insects, notably Hymenoptera (ants, bees, etc.) and Diptera (mosquitoes, flies, fleas, etc.) are highly instructive. He was editor of the ''Bulletin'' of the Wisconsin Natural History Society 1907-09, and in 1910 was appointed editor of ''Psyche'', a journal of entomology. In 1913, while employed at the Bussey Institution, he was part of a three-person team (along with Ernest Tyzzer and Dr. Richard P. Strong) that studied tropical diseases in Peru and Ecuad ...

Agromyzidae
The Agromyzidae are a family commonly referred to as the leaf-miner flies, for the feeding habits of their larvae, most of which are leaf miners on various plants. A worldwide family of roughly 2,500 species, they are small, some with wing length of 1 mm. The maximum size is 6.5 mm. Most species are in the range of 2 to 3 mm. General description Adult agromyzids can be recognized by the distinctive sclerotization of the head. The upper part of the frons, above the ptilinal suture (known as the frontal vitta) is lightly sclerotized and lacks setae, while the lower part of the frons and the dorsal area of the head tends to be much more heavily sclerotized and setaceous. Thus, the frontal vitta often forms a distinctive patch on the head, different in colour and texture from the rest of the head. The compound eyes are usually oval and fairly small, although in some species, they are larger and more circular. The wings are usually hyaline, although those of a few ...

Taxa Named By Charles Thomas Brues
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachycera Families
The Brachycera are a suborder (biology), suborder of the order Diptera. It is a major suborder consisting of around 120 Family (biology), families. Their most distinguishing characteristic is reduced antenna (biology), antenna segmentation. Description A summary of the main physical characteristics is: * antenna (biology), Antenna size (with eight or fewer flagellomeres) is reduced. * The maxilla (arthropod mouthpart), maxillary palp (an elongated appendage near the mouth) has two segments or fewer. * The back portions of the larval head capsule extend into the prothorax (the anterior part of the thorax, which bears the first pair of legs). * Two distinct parts make up of the larval Mandible (insect mouthpart), mandible (lower jaw). * The epandrium and hypandrium of the genitalia are separated in males. * No premandible is present on the lower surface of the Insect mouthparts, labrum (the roof of the mouth). * The configuration of the CuA2 and A1 wing wing vein, veins is distinc ...

Willi Hennig
Emil Hans Willi Hennig (20 April 1913 – 5 November 1976) was a Germans, German biologist and zoologist who is considered the founder of Phylogenesis, phylogenetic systematics, otherwise known as cladistics. In 1945 as a POWs in World War II, prisoner of war, Hennig began work on his theory of cladistics, which he published in German in 1950, with a substantially revised English translation published in 1966. With his works on evolution and systematics he revolutionised the view of the natural order of beings. As a Taxonomy (biology), taxonomist, he specialised in dipterans (true flies). Hennig coined the key terms synapomorphy, Plesiomorphy and symplesiomorphy, symplesiomorphy, and paraphyly. He also asserted, in his "auxiliary principle", that "the presence of apomorphous characters in different species 'is always reason for suspecting kinship [i.e., that species belong to a monophyletic group], and that their origin by convergence should not be presumed a priori' (Hennig, 195 ...

Camillo Rondani
Camillo Rondani (21 November 1808 – 17 September 1879) was an Italian entomologist noted for his studies of Diptera. Early life, family and education Camillo Rondani was born in Parma when the city was part of the French Empire Napoleon having crowned himself King of Italy. The Rondani family were wealthy landowners and of "rich and of ancient origins" with ecclesiastical connections preliminary. Camillo's early education was in a seminary. He then passed into the public school system where, encouraged by Macedonio Melloni his physics and chemistry teacher in the preparatory course for the University of Parma, he did not attend the law lessons though his family had insisted. He attended mineralogy classes given by a Franciscan priest Father Bagatta and was taught natural history, a complementary course to botany for Medicine and Pharmacy. The Reader of Botany to the Athenaeum Parmesan was Professori Giorgio Jan, assistant at the Imperial Museum in Vienna and holder of the ...

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 ...
