Carl Stål
Carl Stål (21 March 1833 – 13 June 1878) was a Swedish entomologist specialising in Hemiptera. He was born at Karlberg Castle, Stockholm on 21 March 1833 and died at Frösundavik near Stockholm on 13 June 1878. He was the son of architect, author and officer Carl Stål then Colonel, Swedish Corps of Engineers. He matriculated at Uppsala University in 1853, studying medicine and passing the medico-philosophical examination in 1857. He then turned to entomology and completed his Ph.D. at the University of Jena in 1859. The same year he became assistant to Carl Henrik Boheman in the Zoological department of the Swedish Museum of Natural History in Stockholm, where, in 1867, he was appointed keeper with the title of professor. He made collecting trips in Sweden and throughout Europe and visited other museums including the collection of Johan Christian Fabricius in Kiel. His study of the Fabrician types resulted in his "Hemiptera Fabriciana". A significant part of Stål's work wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old World
The "Old World" is a term for Afro-Eurasia that originated in Europe , after Europeans became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia, which were previously thought of by their inhabitants as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas. Etymology In the context of archaeology and world history, the term "Old World" includes those parts of the world which were in (indirect) cultural contact from the Bronze Age onwards, resulting in the parallel development of the early civilizations, mostly in the temperate zone between roughly the 45th and 25th parallels north, in the area of the Mediterranean, including North Africa. It also included Mesopotamia, the Persian plateau, the Indian subcontinent, China, and parts of Sub-Saharan Africa. These regions were connected via the Silk Road trade route, and they have a p ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Hemiptera
Hemiptera (; ) is an order (biology), order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, Reduviidae, assassin bugs, Cimex, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking Insect mouthparts, 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 Ant, ants, Bee, bees, Beetle, beetles, or Butterfly, butterflies. In some variations of English, all Terrestrial animal, terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the Colloquialism, colloquial understanding of ''bug''.

Pyrrhocoridae
Pyrrhocoridae is a family of insects with more than 300 species world-wide. Many are red coloured and are known as red bugs and some species are called cotton stainers because their feeding activities leave an indelible yellow-brownish stain on cotton crops. A common species in parts of Europe is the firebug, and its genus name ''Pyrrhocoris'' and the family name are derived from the Greek roots for fire "pyrrho-" and bug "coris". Members of this family are often confused with, but can be quickly separated from, Lygaeidae by the lack of ocelli (simple eyes) on the top of the head. Description The membrane of the forewing has one or two cells from which about 7-8 branching veins emerge that may have branches that fuse together (anastomose) while the main veins reach the margins of the wing. They have three tarsal segments. They can be very difficult to separate from some members of the family Largidae, which also share some of these characters and belong to the same super family. ...

Lygaeidae
The Lygaeidae are a family in the Hemiptera (true bugs), with more than 110 genera in four subfamilies. The family is commonly referred to as seed bugs, and less commonly, milkweed bugs, or ground bugs. However, while many of the species feed on seeds, some feed on sap ( mucivory) or seed pods, others are omnivores and a few, such as the wekiu bug, are carnivores that feed exclusively on insects. Insects in this family are distributed across the world, including throughout North America. The family was vastly larger, but numerous former subfamilies have been removed and given independent family status, including the Artheneidae, Blissidae, Cryptorhamphidae, Cymidae, Geocoridae, Heterogastridae, Ninidae, Oxycarenidae and Rhyparochromidae, which together constituted well over half of the former family. The bizarre and mysterious beetle-like Psamminae were formerly often placed in the Piesmatidae, but this is almost certainly incorrect. Their true affiliations, however, are not en ...

Ocelli
A simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates. In this sense "simple eye" is distinct from a multi-lensed "compound eye", and is not necessarily at all simple in the usual sense of the word. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods. They possess a wide variety of novel solutions to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of humans and of other large animals such as most cephalopods, are ''camera eyes'' and ...

Melamphaus Agnatus
''Melamphaus'' is an Old World genus of true bugs in the family Pyrrhocoridae, the cotton stainers. They are often confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli on the head. The genus has adults with large and characteristic oval shape and the body is densely covered in short hair. The head behind the eye narrows slightly and the eyes are at a distance from the fore edge of the pronotum. The edge of the pronotum is not extended to the sides or bent down. The metathoracic scent gland has an ostiole with a peritreme and a deep furrow. The sutures on the underside of the abdominal segments between 4 and 5; and between 5 and 6 are strongly curved forwards. Many species may swarm seasonally on seeds of specific trees. ''Melamphaus faber'' is known to be found in large numbers on ''Hydnocarpus anthelmetica'' and ''H. wightiana'' in Singapore. Species that have been included in the genus include: * '' Melamphaus agnatus'' Bergroth, 1894 * ''M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
