Zelus Annulosus
''Zelus annulosus'' is an assassin bug found in South America. It frequently associates with ''Hirtella physophora'' (Chrysobalanaceae), a plant that houses colonies of plant-ants ''Allomerus decemarticulatus'' and provides the ants with nectar. Some species of ''Zelus In Greek mythology, Zelus or Zelos (; Ancient Greek: Ζῆλος ''Zēlos,'' literally 'zeal') was the daimon that personifies dedication, emulation, eager rivalry, envy, jealousy, and zeal. The English word "zeal" is derived from his name.

''Zelus annulosus'' apparently is able to avoid being attacked by the ants by walking primarily on the plant's trichomes, which shield the assassin bug from the ants, but still allow ''Z. annulosus'' to be protected by having the ants in the vicinity.

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] |
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 recognized subfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Hirtella Physophora
''Hirtella physophora'' is a species of plant in the family Chrysobalanaceae Chrysobalanaceae is a family of flowering plants, consisting of trees and shrubs in 27 genera and about 700 species of pantropical distribution with a centre of diversity in the Amazon. Some of the species contain silica in their bodies for ri .... It forms an association with the ant species, '' Allomerus decemarticulatus''. The ants live in honeycombed cylinders they attach to the plant's stems. The plant nearly always has these ants associated with it. References physophora {{Malpighiales-stub ...

Allomerus Decemarticulatus
''Allomerus decemarticulatus'' is an Amazonian ant species found in the tropics of South America. This species is most notable for the workers’ complex and extreme predatory behavior, which involves a symbiosis with both a plant and fungal species. They live in leaf pockets of a host plant species, '' Hirtella physophora''. These leaf pockets are areas inside of the plant between the leaves and the stem. Each colony, which consists of about 1,200 workers, inhabits a single tree; however, the ants are spread among the leaf pockets, with typically 40 workers per pocket. Their diet primarily consists of large insects that are captured on the plant, but they also eat some kinds of food bodies produced by the plant as well as its nectar. They are able to capture their prey, which is much larger than themselves, by constructing a platform that acts as a trap for the unsuspecting prey. The ants hide in the trap and attack when any insect lands on it. This technique is an example ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zelus
In Greek mythology, Zelus or Zelos (; Ancient Greek: Ζῆλος ''Zēlos,'' literally 'zeal') was the daimon that personifies dedication, emulation, eager rivalry, envy, jealousy, and zeal. The English word "zeal" is derived from his name. His Roman equivalent was Invidia. Family Zelus was the son of Pallas (the Titan) and Styx (an Oceanid). His siblings were Nike (Victory), Kratos (Strength) and Bia (Force). Mythology Titanomachy Zelus together with his siblings were winged enforcers who stood in attendance at Zeus' throne and formed part of his retinue. Theogony : And Styx the daughter of Okeanos (Oceanus) was joined to Pallas and bare Zelos (Zelus, Emulation) and trim-ankled Nike (Victory) in the house. Also she brought forth Kratos (Cratus, Strength) and Bia (Force), wonderful children. These have no house apart from Zeus, nor any dwelling nor path except that wherein God leads them, but they dwell always with Zeus the loud-thunderer. For so did Styx the ...

Insects Of South America
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] |
