Plectroctena Mandibularis
''Plectroctena mandibularis'', called the ringbum ant or millipede munching ant, is a large species of ant that ranges from the Eastern Cape, South Africa, through East Africa to Ethiopia. Their workers forage singly in open terrain, and their colony size seldom exceeds fifty individuals. It is one of the large ''Plectroctena'' species, including '' P. conjugata'' and '' P. minor'', that specialize on adult millipedes as prey. The nest is composed of chambers that are typically located two feet or more below the surface, and the nest entrances are usually marked by large piles of earth. They get their colloquial, common name from their tendency to prey on millipedes Millipedes (originating from the Latin , "thousand", and , "foot") are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derive ....

Frederick Smith (entomologist)
Frederick Smith (30 December 1805 – 16 February 1879) was a British entomologist who worked at the zoology department of the British Museum from 1849, specialising in the Hymenoptera. Smith was born near York to William Smith and went to school at Leeds. He then studied under landscape engraver William Bernard Cooke, W.B. Cooke along with his nephew William Edward Shuckard. Together they took an interest in insects, especially the ants and bees. In 1841, following the death of William Bainbridge, he became a curator of the collections and the library of the Entomological Society of London. As an engraver he produced copies based on the works of Turner, Constable and David Roberts. He also worked with Gray arranging Hymenoptera in the British Museum. In 1849 he succeeded Edward Doubleday as a member of the zoologicy department. He then gave up his art work but produced the plates for Wollaston's ''Insecta Maderensia'' (1854) and for papers in the Transactions of the Entomologic ...

Millipede
Millipedes (originating from the Latin , "thousand", and , "foot") are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from Latin for "thousand feet", no species was known to have 1,000 or more until the discovery in 2020 of '' Eumillipes persephone'', which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures. Most millipedes are slow-moving detritivores, eat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Cape
The Eastern Cape ( ; ) is one of the nine provinces of South Africa. Its capital is Bhisho, and its largest city is Gqeberha (Port Elizabeth). Due to its climate and nineteenth-century towns, it is a common location for tourists. It is also known for having been home to many anti-apartheid activists, including Nelson Mandela. The second largest province in the country (at 168,966 km2) after the Northern Cape, it was formed in 1994 out of the Xhosa people, Xhosa homelands or bantustans of Transkei and Ciskei, together with the eastern portion of the Cape Province. The central and eastern part of the province is the traditional home of the indigenous Xhosa people. In 1820 this area, which was known as the Xhosa Kingdom, began to be settled by Europeans who originally came from England, Scotland and Ireland. Eastern Cape is the only province in South Africa were the number of Black Africans declined from 86.6% to 85.7% since Apartheid ended in 1994. History The Eastern Cape p ...

East Africa
East Africa, also known as Eastern Africa or the East of Africa, is a region at the eastern edge of the Africa, African continent, distinguished by its unique geographical, historical, and cultural landscape. Defined in varying scopes, the region is recognized in the United Nations Statistics Division United Nations geoscheme for Africa, scheme as encompassing 18 sovereign states and 4 territories. It includes the Horn of Africa to the North and Southeastern Africa to the south. Definitions In a narrow sense, particularly in English-speaking contexts, East Africa refers to the area comprising Kenya, Tanzania, and Uganda, largely due to their shared history under the Omani Empire and as parts of the British East Africa Protectorate and German East Africa. Further extending East Africa's definition, the Horn of Africa—comprising Djibouti, Eritrea, Ethiopia, and Somalia—stands out as a distinct geopolitical entity within East Africa.Robert Stock, ''Africa South of the Sahara, ...

Plectroctena Conjugata
230px, ''Plectroctena mandibularis'' ''Plectroctena'' is an Afrotropical genus of ants, with most species occurring in the rainforest zones of West and Central Africa. Some species are cryptic or subterranean foragers, while others forage in open grassland terrain. The workers forage singly or in groups of 2 to 3. They nest in the earth at varying depths, or in collapsed logs. They prey mainly on millipedes, including their young or eggs. Colony structure A colony of '' P. lygaria'' (a small species of the ''mandibularis''-group) may number in excess of 300 adults. An excavated colony in the Ivory Coast consisted of 277 workers, 8 alate queens, and 42 alate males. Consequently 15% of their number was allocated to reproductives at the specific time. The colony size of '' P. mandibularis'' however, seldom exceeds 50 individuals. Nests In a colony of '' P. lygaria'', the nest chambers are located at shallow depth, in moist soil under dense leaf litter. The deepest chamber may be lo ...

Anthill
An ant colony is a population of ants, typically from a single species, capable of maintaining their complete lifecycle. Ant colonies are eusocial, communal, and efficiently organized and are very much like those found in other social Hymenoptera, though the various groups of these developed sociality independently through convergent evolution. The typical colony consists of one or more egg-laying queens, numerous sterile females (workers, soldiers) and, seasonally, many winged sexual males and females. In order to establish new colonies, ants undertake flights that occur at species-characteristic times of the day. Swarms of the winged sexuals (known as alates) depart the nest in search of other nests. The males die shortly thereafter, along with most of the females. A small percentage of the females survive to initiate new nests. Etymology The term "ant colony" refers to a population of workers, reproductive individuals, and brood that live together, cooperate, and treat on ...
