Nannodastiidae
Nannodastiidae are a small family of acalyptrate flies placed in two genera. They were formerly included within the Ephydridae or shore flies. These are small to minute flies which are dull coloured with clear wings. They are identified by a combination of seta In biology, setae (singular seta ; from the Latin word for "bristle") are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Annelid setae are stiff bristles present on the body. Th ...l characters visible only under a microscope and genital features which require specimen dissection. They are found along coasts and in bat caves rich in guano. References {{sphaeroceroidea-stub Brachycera families ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acalyptratae
The Acalyptratae or Acalyptrata are a subsection of the Schizophora, which are a section of the order Diptera, the "true flies". In various contexts the Acalyptratae also are referred to informally as the acalyptrate muscoids, or acalyptrates, as opposed to the Calyptratae. All forms of the name refer to the lack of calypters in the members of this subsection of flies. An alternative name, Acalypterae is current, though in minority usage. It was first used by Pierre-Justin-Marie Macquart in 1835 for a section of his tribe Muscides; he used it to refer to all acalyptrates plus scathophagids and phorids, but excluding Conopidae. The confusing forms of the names stem from their first usage; ''Acalyptratae'' and ''Acalyptrata'' actually are adjectival forms in New Latin. They were coined in the mid 19th century in contexts such as "Muscae Calyptratae and Acalyptratae" and "Diptera Acalyptrata", and the forms stuck. The Acalyptratae are a large assemblage, exhibiting very diverse h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ephydridae
Ephydridae (shore fly, sometimes brine fly) is a family of insects in the order Diptera. Shore flies are tiny flies that can be found near seashores or at smaller inland waters, such as ponds. About 2,000 species have been described worldwide, including Ochthera. The petroleum fly, ''Helaeomyia petrolei'', is the only known insect whose larvae live in naturally occurring crude petroleum. Another notable species is '' Ephydra hians'' which lives in vast number at Mono Lake. Description For terms, see Morphology of Diptera. The flies are minute to small (0.9 to 7.0 mm), with black or gray colorations. Wings are sometimes patterned. Costa with two interruptions are present in first section, near the humeral cross-vein and again near the end of vein 1. The second basal cell is not separated from the discal cell. Arista are bare or with hairs on the upper side (plumose on the upper side). The mouth opening is very large in some species. The ratio of vertical diameter of eye ...

Seta
In biology, setae (singular seta ; from the Latin word for "bristle") are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. Crustaceans have mechano- and chemosensory setae. Setae are especially present on the mouthparts of crustaceans and can also be found on grooming limbs. In some cases, setae are modified into scale like structures. Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and allows th ...
