Eristalini
Eristalini is a tribe of hoverflies. Several species are well-known honeybee mimics, such as the drone fly ''Eristalis tenax'', while other genera such as '' Helophilus'' and '' Parhelophilus'' exhibit wasp-like patterns of yellow and black stripes, both strategies to avoid predation by visual predators such as birds. They breed in decaying organic materials such as run-offs from dung heaps ('' Eristalis'') or in ponds and ditches (e.g. '' Anasimyia''). Some others, such as ''Myathropa'' and '' Mallota'', breed in wet rotting tree stumps and rot holes. A characteristic feature of this tribe is the " rat-tailed maggot" with a rear positioned telescopic breathing tube, allowing the larvae to breathe while living submerged in water or mud. This feature is also shared with another hoverfly tribe the Sericomyiini though those flies do not share the characteristic eristaline dip in wing vein R4+5.

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.

Hoverfly Genera
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae ( maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most ...

Insects Of Madagascar
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. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diptera Of Africa
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eugène Séguy
Eugene Séguy (21 April 1890 – 1 June 1985) was a French entomologist and artist who specialised in Diptera. He held a chair of entomology at the Muséum national d'histoire naturelle in Paris from 1956 to 1960. He is also known for establishing the Diptera section at that museum. This entomologist is often confused with a French artist with a similar name: Émile-Allain Séguy (1877–1951). The latter is known for his pochoir artworks representing plants and insects.

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

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 dif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
