Probergrothius Angolensis
''Probergrothius angolensis'', sometimes known as the Welwitschia bug, is a species of true bug found in the Namib desert and nearby regions. Relationship with ''Welwitschia'' They are best known for their association with the unusual plant ''Welwitschia mirabilis'', also endemic to the area, but it is in doubt whether they actually serve a role in pollination or only drink ''Welwitschia'' sap.

True Bug
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles. The term is a ...

Namib Desert
The Namib ( ; pt, Namibe) is a coastal desert in Southern Africa. The name is of Khoekhoegowab origin and means "vast place". According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to inland to the foot of the Great Escarpment. Annual precipitation ranges from in the most arid regions to at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and conta ...

Probergrothius Angolensis On Welwitschia 1
''Probergrothius'' is an Old World genus of true bugs in the family Pyrrhocoridae. The genus was previously referred to as '' Odontopus'', but that name was already in use for a genus of weevils, and was therefore replaced by ''Probergrothius'' in 1904. Members of this genus are reported to feed mainly on members of the plant order Malvales, including '' Sterculia,'' baobab (''Adansonia''), and kapok ('' Ceiba'' or ''Bombax''), but will feed on others as well. The welwitschia bug, ''Probergrothius angolensis,'' feeds on ''Welwitschia'' seeds, which is a gymnosperm, unlike the Malvales, which are angiosperms.

Welwitschia Mirabilis
''Welwitschia'' is a monotypic gymnosperm genus, comprising solely the distinctive ''Welwitschia mirabilis'', endemic to the Namib desert within Namibia and Angola. ''Welwitschia'' is the only living genus of the family Welwitschiaceae and order Welwitschiales in the division Gnetophyta, and is one of three living genera in Gnetophyta, alongside ''Gnetum'' and ''Ephedra''. Informal sources commonly refer to the plant as a "living fossil". Naming ''Welwitschia'' is named after the Austrian botanist and doctor Friedrich Welwitsch, who described the plant in Angola in 1859. Welwitsch was so overwhelmed by the plant that he, "could do nothing but kneel down ..and gaze at it, half in fear lest a touch should prove it a figment of the imagination." Joseph Dalton Hooker of the Linnean Society of London, using Welwitsch's description and collected material along with material from the artist Thomas Baines who had independently recorded the plant in Namibia, described the species.

Fungus
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspergillus Niger
''Aspergillus niger'' is a mold classified within the ''Nigri'' section of the ''Aspergillus'' genus. The ''Aspergillus'' genus consists of common molds found throughout the environment within soil and water, on vegetation, in fecal matter, on decomposing matter, and suspended in the air. Species within this genus often grow quickly and can sporulate within a few days of germination. A combination of characteristics unique to ''A. niger'' makes the microbe invaluable to the production of many acids, proteins and bioactive compounds. Characteristics including extensive metabolic diversity, high production yield, secretion capability, and the ability to conduct post-translational modifications are responsible for ''A. niger's'' robust production of secondary metabolites. ''A. niger's'' capability to withstand extremely acidic conditions makes it especially important to the industrial production of citric acid. ''A. niger'' causes a disease known as "black mold" on certain fruits an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Probergrothius sexpunctatus'' is a species of true bug found in West-Central Africa. The name has been misattributed for many decades to a related species, ''Probergrothius angolensis ''Probergrothius angolensis'', sometimes known as the Welwitschia bug, is a species of true bug found in the Namib desert and nearby regions.

''P. sexpunctatus'', as its name suggests, has six prominent black spots on its wings (3 per wing; 2 anteriorly and 1 posteriorly), distinguishing it from the visually similar ''P. angolensis'' where the two anterior wing spots are typically fused, making four wing spots (2 per wing; 1 anteriorly and posteriorly). ''P. sexpunctatus'' also typically has a reddish pronotum and legs, which are black (or almost black) in ''P. angolensis'', however this characte ...

Insects Described In 1902
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
