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. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Hoverfly
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 mammals, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eristalinae
Eristalinae (or Milesiinae) are one of the four subfamilies of the fly family Syrphidae, or hoverflies. A well-known species included in this subfamily is the dronefly, ''Eristalis tenax''. Species in this subfamily are often misclassified as bees instead of flies due to their exceptional Mimicry, especially to resemble Honeybees (family Apidae). The best strategy for proper identification is to look at their eyes and wings and compare with fly morphology, to determine membership of family Syrphidae and/or of order Hymenoptera. Taxonomy This subfamily consists of the following tribes: * Brachyopini * Callicerini * Cerioidini * Eristalini * Sericomyiini * Eumerini * Milesiini * Pipizini * Rhingiini * Spheginobacchini * Volucellini gallery Brachyopa daeckei.jpg, '' Brachyopa daeckei'' actual size Sphiximorpha subsessilis, Parc de Woluwé, Brussels (34851582946).jpg, ''Sphiximorpha subsessilis'' Namaste!

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.

Helophilus
''Helophilus'' are a diverse genus of moderate to large hoverflies, that appear somewhat bee-like. Larvae filter-feed in organic rich water.

Peter Fredrik Wahlberg
Peter Fredrik Wahlberg (19 June 1800, in Gothenburg – 22 May 1877, in Stockholm) was a Sweden, Swedish entomologist and professor at the University College of Stockholm. Wahlberg was a member of the Royal Swedish Academy of Sciences from 1830, and served as the academy's secretary from 1848 to 1866. The island Wahlbergøya, the largest of Vaigattøyane, is named after him. Works *''Om Rhaphium flavipalpe Zett. fvers. K. Vetenskapsakad.

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Blac ...

Diptera Of Europe
Flies are insects of the Order (biology), order Diptera, the name being derived from the Ancient Greek, 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-fly, horse-flies, crane fly, crane flies, hoverfly, hoverflies and others, although only about 125,000 species have Species description, 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 ...
