Natalimyzidae
''Natalimyza'' is a genus of flies placed in the family Natalimyzidae and known as African grass flies. There are about 30 species in Africa which are found mainly in grasslands where their larvae are thought to feed on decaying plant material. They are small (less than long) yellow to brown and appear like flies in the families Chyromyidae or Opomyzidae Opomyzidae is a family of Acalyptratae, acalyptrate Fly, Diptera. They are generally small, slender, yellow, brown or black coloured flies. The larval food plants are grasses, including cereal crops, the adults are mainly found in open habitats. ..., but differentiated by bristles on the head, having four fronto-orbital bristles.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Chyromyidae
Chyromyidae are small to very small cyclorrhaphous, acalyptrate flies (Diptera) currently classified within the Heleomyzoidea by most authors. The majority have a pale yellow integument and bright iridescent green, red or purple eyes. The family is represented in all continents except Antarctica. There are about 150 named species in this family worldwide. There has been no comprehensive taxonomic study to elucidate the generic limits of species in the family. Currently, only four genera are recognised, but ongoing studies of the African species indicate that there are more. Biology The biology of Chyromyidae is poorly known and no life history of any species has been elucidated. Adults are xerophilic and have been collected on flowering plants. There appears to be some association with bird and mammalian nests,Smith, K.G.V. 1989. ''An introduction to the immature stages of British flies''.

Opomyzidae
Opomyzidae is a family of Acalyptratae, acalyptrate Fly, Diptera. They are generally small, slender, yellow, brown or black coloured flies. The larval food plants are grasses, including cereal crops, the adults are mainly found in open habitats. Some species being Agriculture, agricultural Pest (organism), pests. Description For terms see Morphology of Diptera. Small slender yellow, brown, reddish or black flies. The narrow wings are usually with light or dark-colored spots (darkly marked crossveins apical spot). Head with one pair of backwardly directed orbital (frontal bristles) bristles. Scattered interfrontal setulae are present Ocellar bristles are present. Postvertical bristles are absent (rarely present). Vibrissae absent but Geomyza with a strong bristle near the vibrissal angle. Ocelli are present and the arista is pubescent or with long hairs. Tibae without preapical dorsal bristles. R1 is short, the subcosta ends near the break of the costa (usually incomplete but ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachycera Families
The Brachycera are a suborder of the order Diptera. It is a major suborder consisting of around 120 families. Their most distinguishing characteristic is reduced antenna segmentation. Description A summary of the main physical characteristics is: * Antenna size (with eight or fewer flagellomeres) is reduced. In many species the third segment, the flagellum, is fused, except from a bristle called the arista that is sticking out from the fused flagellum. The arista consist of no more than three segments called aristomeres. * The 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 (lower jaw). * The epandrium and hypandrium of the genitalia are separated in males. * No premandible is present on the lower surface of the labrum (the roof of the mouth). * T ...
