Rhynocoris Tristis
''Rhynocoris tristis'' is a species of assassin bug family (Reduviidae), in the subfamily Harpactorinae. ''R. tristis'' is a polyphagous predator found in sub-Saharan Africa Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the List of sov .... Life History ''R. tristis'' is associated with '' Stylosanthes guinaensis'', and this association is thought to be due to the prey species attracted by flowers of ''S. guinaensis''. ''R. tristis'' is unusual in the insect world in that males provide paternal care by guarding egg masses from parasitic wasps and insect predators. Males will also cannibalize some of the eggs that they guard. ''R. tristis'' prefers to lay its eggs on the stems of plants, in contrast to most members of the harpactorinae, which prefer to lay them on the undersides of leaves. Refere ...

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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assassin Bug
The Reduviidae are a large cosmopolitan family of the order Hemiptera (true bugs). Among the Hemiptera and together with the Nabidae almost all species are terrestrial ambush predators: most other predatory Hemiptera are aquatic. The main examples of nonpredatory Reduviidae are some blood-sucking ectoparasites in the subfamily Triatominae. Though spectacular exceptions are known, most members of the family are fairly easily recognizable; they have a relatively narrow neck, sturdy build, and a formidable curved proboscis (sometimes called a rostrum). Large specimens should be handled with caution, if at all, because they sometimes defend themselves with a very painful stab from the proboscis. Taxonomy The Reduviidae are members of the suborder Heteroptera of the order Hemiptera. The family members are almost all predatory, except for a few blood-sucking species, some of which are important as disease vectors. About 7000 species have been described, in more than 20 recogniz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harpactorinae
The Harpactorinae are a large subfamily of the Reduviidae (assassin bugs). About 300 genera and 2,000 species worldwide have been described. Some of the species of the genera ''Zelus'', ''Pselliopus'', ''Sinea'', and ''Apiomerus'' are of interest as biological pest control agents. Tribes and genera The genera of six tribes include: Apiomerini New World resin bugs: auth. Amyot & Audinet-Serville, 1843 *''Agriocleptus'' Stål, 1866 *''Agriocoris'' Stål, 1866 *''Amauroclopius'' Stål, 1868 *''Apiomerus'' Hahn, 1831 *''Beharus'' Fabricius, 1803 *'' Calliclopius'' Stål, 1868 *'' Foucartus'' Berenger, 2006 *''Heniartes'' Spinola, 1840 *'' Manicocoris'' Fabricius, 1787 *'' Micrauchenus'' Amyot & Servile, 1843 *'' Ponerobia'' Amyot & Serville, 1843 *'' Sphodrolestes'' Stål, 1866 Diaspidiini African resin bugs: auth.

Sub-Saharan Africa
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region (e.g. UN, WHO, World Bank, etc.). The African Union uses a different regional breakdown, recognizing all 55 member states on the continent - grouping them into 5 distinct and standard regions. The term serves as a grouping counterpart to North Africa, which is instead grouped with the definition of MENA (i.e. Middle East–North Africa) as it is part o ...

Stylosanthes Guinaensis
''Stylosanthes'' is a genus of flowering plants in the legume family, Fabaceae and contains numerous highly important pasture and forage species. It was recently assigned to the informal monophyletic ''Pterocarpus'' clade of the Dalbergieae. The common name pencilflower is sometimes used for plants in this genus. Description The genus is characterised by trifoliate leaves and small yellow flowers Species may be annual or perennial and morphology varies between species as well as within species in response to grazing pressure. Some species such as '' S. scabra'' grow as a low woody shrub to 1.5 m, while others such as '' S. humilis'' will grow as a herbaceous shrub but can adopt a prostrate growth form and thrive under high grazing pressure. Taxonomy and range Taxonomy of the genus remains unsettled and controversial, with various authors favouring between 25 and 42 species, with at least 40 additional synonyms. The taxonomy is complicated by the existence of numerous na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hemiptera Of Africa
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.

Insects Described In 1855
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] |
