Alcimus (fly)
''Alcimus'' is a genus of flies in the family Asilidae, the robber flies and assassin flies. There are about 26 species which are native to the Afrotropics The Afrotropical realm is one of Earth's eight biogeographic realms. It includes Africa south of the Sahara Desert, the majority of the Arabian Peninsula, the island of Madagascar, southern Iran and extreme southwestern Pakistan, and the island .... These are slim, elongate robber flies; the thorax appears broad relative to the abdomen. Their colouring generally includes black or dark brown streaking on a chestnut matrix. Most species in this genus are adapted to life on bare ground, but they are also often found resting on the upper parts of bushes. Robber flies are predators, and those in the genus ''Alcimus'' prey on a wide variety of arthropods; grasshoppers and lepidoptera comprise a large part of their diet.

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachycera
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. * 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). * The configuration of the CuA2 and A1 wing veins is distinct. Brachyceran flies can also be distinguished through behavior. Many of the species are predators or scavengers. Classification The structure of subgroups wit ...

Asilomorpha
The Brachyceran infraorder Asilomorpha is a large and diverse group of flies, containing the bulk of the non muscoid Brachycera. The larvae of asilomorphs are extremely diverse in habits, as well. Classification In most modern classifications, the infraorder Asilomorpha is not recognized, as it is paraphyletic; the Empidoidea are the sister taxon to the Muscomorpha (used here in the same sense as the traditional Cyclorrhapha, not following the Tree of Life Web Project system in this one instance). However, these modern classifications are not Linnaean, and - while relatively easy to visualize on a phylogenetic tree diagram - do not lend themselves to any classification that uses Linnaean ranks (''see'' discussion ''for details''). Also, some classifications place the Nemestrinoidea Nemestrinoidea is a small, monophyletic superfamily of flies, whose relationship to the other Brachycera is uncertain; they are sometimes grouped with the Tabanomorpha rather than the Asilomorpha.

Asiloidea
The Asiloidea comprise a very large superfamily insects in the order Diptera, the true flies. It has a cosmopolitan distribution, occurring worldwide. It includes the family Bombyliidae, the bee flies, which are parasitoids, and the Asilidae, the robber flies, which are predators of other insects. Description Adult Asiloidea are large and showy flies in terms of general appearance. They can be recognised by the following features: antenna with no more than 4 flagellomeres, leg empodium usually setiform or absent; wing with cell cup elongate and vein CuA2 ending freely on the wing margin or meeting with vein A1 at or near the wing margin. In families Mydidae, Apioceridae, and Asilidae, the head is at least slightly concave between the eyes and the ocelli, and both sexes are dichoptic (with a clear separation between the eyes). In Therevidae, Apsilocephalidae, and Scenopinidae, the males are usually holoptic (eyes meet at top of head). Known larvae of this superfamily have p ...

Asilidae
The Asilidae are the robber fly family, also called assassin flies. They are powerfully built, bristly flies with a short, stout proboscis enclosing the sharp, sucking hypopharynx. The name "robber flies" reflects their notoriously aggressive predatory habits; they feed mainly or exclusively on other insects and, as a rule, they wait in ambush and catch their prey in flight. Overview The Asilidae are a family in the order Diptera, the true flies. The common name for members of the family is the robber flies. The Asilidae are cosmopolitan, with over 7000 described species. Latreille was the authority for establishing the family in 1802. The Asilidae, together with Bombyliidae and Therevidae, are the most representative families of the superfamily of Asiloidea and they form one of the most characteristic groups of the lower Brachycera. Robber flies have stout, spiny legs and three simple eyes (ocelli) in a characteristic depression on the tops of their head between their two ...

Hermann Loew
Friedrich Hermann Loew (19 July 1807 – 21 April 1879) was a German entomologist who specialised in the study of Diptera, an order of insects including flies, mosquitoes, gnats and midges. He described many world species and was the first specialist to work on the Diptera of the United States. Biography Early years Hermann Loew was born in Weissenfels, Saxony a short distance south of Halle (Germany). The Loew family, though not wealthy, was well-placed. Loew's father was a functionary for the Department of Justice of the Duchy of Saxony who later became a ''Geheimer Regierungsrath'' of Prussia. Between 1817 and 1829 Loew attended first the Convent school of Rossleben, then the University of Halle-Wittenberg, graduating in mathematics, philology and natural history. Teacher, tutor and husband Recognizing his abilities as a mathematician, the university, on his graduation, appointed him as a lecturer in the same subjects. In 1830 he went to Berlin and gave lessons in differen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afrotropics
The Afrotropical realm is one of Earth's eight biogeographic realms. It includes Africa south of the Sahara Desert, the majority of the Arabian Peninsula, the island of Madagascar, southern Iran and extreme southwestern Pakistan, and the islands of the western Indian Ocean. It was formerly known as the Ethiopian Zone or Ethiopian Region. Major ecological regions Most of the Afrotropic, with the exception of Africa's southern tip, has a tropical climate. A broad belt of deserts, including the Atlantic and Sahara deserts of northern Africa and the Arabian Desert of the Arabian Peninsula, separate the Afrotropic from the Palearctic realm, which includes northern Africa and temperate Eurasia. Sahel and Sudan South of the Sahara, two belts of tropical grassland and savanna run east and west across the continent, from the Atlantic Ocean to the Ethiopian Highlands. Immediately south of the Sahara lies the Sahel belt, a transitional zone of semi-arid short grassland and vachellia sav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
