Camponotini
Camponotini is a tribe containing 2 extinct ant genera and 8 extant ant genera, including '' Camponotus'' (carpenter ants). Ants in the Camponotini tribe are the primary hosts of ''Ophiocordyceps unilateralis'', also called the zombie-ant fungus A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms.

Ophiocordyceps Unilateralis
''Ophiocordyceps unilateralis'', commonly known as zombie-ant fungus, is an entomopathogenic fungus, insect-pathogenic fungus, discovered by the British naturalist Alfred Russel Wallace in 1859. Zombie ants, infected by the ''Ophiocordyceps unilateralis'' fungus, are predominantly found in Tropical rainforest, tropical rainforests. These fungi thrive in warm, humid environments, which are ideal for their growth and reproduction. However, they can also be found in warm-temperate forest systems. The fungus primarily targets ants from the tribe Camponotini, including carpenter ants (genus ''Camponotus''). ''O. unilateralis'' infects ants of the tribe Camponotini, with the full pathogenesis being characterized by alteration of the behavioral patterns of the infected ant. Infected hosts leave their canopy nests and foraging trails for the forest floor, an area with a temperature and humidity suitable for fungal growth; they then use their Mandible (insect mouthpart), mandibles to at ...

Colobopsis
''Colobopsis'' is a genus of ants in the subfamily Formicinae. This genus was first described in 1861 by Mayr and contains 95 species. The type species is ''Colobopsis truncata''. Description As part of Camponotini, ''Colobopsis'' workers have distinctive Mandible (insect mouthpart), mandibular dentition (5-8 teeth with the 3rd tooth from the apex not being reduced), Antenna (biology), antennae 12-segmented and antennal separations well separated from the posterior Clypeus (arthropod anatomy), clypeal margin. ''Colobopsis'' workers are dimorphic, being divided into major workers and minor workers. The major workers generally have Phragmosis, phragmotic heads that are truncate to varying extents. This may cause them to be confused for ''Carpenter ant, Camponotus'' and vice versa, since some ''Camponotus'' also have phragmotic heads. Queens of ''Colobopsis'' have phragmotic heads as well. Workers in the ''Colobopsis cylindrica'' group have greatly developed mandibular glands tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overbeckia
''Overbeckia'' is a genus of ants in the subfamily Formicinae originally containing only the single species ''Overbeckia subclavata''. Although the genus has been known over 100 years only from Singapore Singapore, officially the Republic of Singapore, is an island country and city-state in Southeast Asia. The country's territory comprises one main island, 63 satellite islands and islets, and one outlying islet. It is about one degree ..., where its nests were found in hollow branches of bamboo and other plants, a revision study by Klimes and coll. in 2022 showed that these ants occur across tropical SA Asia to Australasia and re-described the genus, ''Overbeckia subclavata''. and described two new species, ''Overbeckia jambiensis'', and ''Overbeckia papuana''. The study also showed that more recent findings of ''Overbeckia'' in Australia are likely ''O. papuana,'' based on morphology.

Formicinae
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development. Formicines retain some primitive features, such as the presence of cocoons around pupae, the presence of ocelli in workers, and little tendency toward reduction of palp or antennal segmentation in most species, except subterranean groups. Extreme modification of mandibles is rare, except in the genera '' Myrmoteras'' and '' Polyergus''. However, some members show considerable evolutionary advancement in behaviors such as slave-making and symbiosis with root-feeding hemipterans. Finally, all formicines have very reduced stings and enlarged venom reservoirs, with the venom gland, specialized (uniquely among ants) for the production of formic acid. All members of the Formicinae "have a one-segmented petiole in the form of a vertical scale". Identification Formicine ants have a single node-like or scale-like petiole (postpetiole entirely lacking) and the apex of th ...

Polyrhachis
''Polyrhachis'' is a genus of formicine ants found in the Old World with over 600 species. The genus is yet to be comprehensively resolved and contains many varied species including nest-weavers (e.g. ''Polyrhachis dives''), swimming workers (e.g. '' Polyrhachis sokolova''), soil (e.g. ''Polyrhachis proxima'') and tree-dwellers (e.g. ''Polyrhachis bicolor''). The first fossil record of this genus was of '' Polyrhachis annosa'' from the Miocene. General morphology Size: Workers range in size approx 5–10mm in length. Eyes developed, no ocelli. Antennae have 12 segments. Antennal insertions situated far from posterior margin of clypeus. Mesosoma of most species have spines on one or more of its pronotal, mesonotal or propodeal components. Petiole armed with spines or teeth. First gastral tergite well developed, longer in dorsal view than exposed parts of the following terga together. Opening at gastral apex for release of venom lacking a radial fringe of hairs. Ecology ''Polyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dinomyrmex
''Dinomyrmex'' is a monotypic genus of ant containing the species ''Dinomyrmex gigas'' or giant forest ant. ''D. gigas'' is a large species of ant, native to Southeast Asian forests. It is one of the largest ants in existence, measuring in at for normal workers, and for the soldiers. Honeydew makes up 90% of their diet, but they will also consume insects and bird droppings. The ant is an effective forager, utilizing both efficient communication and recruitment. A handful of these ants may meet at night to engage in what has been observed to be ritual battle. These fights can continue for several months. Colonies consist of typically about 7,000 workers, distributed unevenly among several nests. There are two types of workers, with the larger ones almost three times as heavy. They forage mainly at night, however, some workers will be outside the nest during the day. Distribution This species is found in Southeast Asian rain forests from Sumatra, Singapore, Malaysia, Borneo to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camponotus Ligniperda
''Camponotus ligniperda'', the brown-black carpenter ant, is a common species of carpenter ant distributed widely throughout Europe. Found in a variety of woodland habitats, they commonly nest on the ground in dry tree stumps, dead fallen trees, or beneath stones and wooden logs that are partially buried. ''C. ligniperda'' is an ecologically dominant species wherever it is found due to both its large size and particularly aggressive nature. Description ''Camponotus ligniperda'' is one of if not the largest extant ant species found in Europe, with queens reaching lengths of 16–18 mm (potentially 20 mm when physogastric) followed by 14–15 mm major workers. Intermediate and minor workers measure on average 7–10 mm. Individuals are typically bicolored with a black head and a reddish brown thorax which color bleeds into the legs and anterior segment of the dark colored gaster. Considered a sister species to '' Camponotus herculeanus'', the species can be disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auguste Forel
Auguste-Henri Forel (; 1 September 1848 – 27 July 1931) was a Swiss myrmecologist, neuroanatomist, psychiatrist and former eugenicist, notable for his investigations into the structure of the human brain and that of ants. He is considered a co-founder of the neuron theory. Forel is also known for his early contributions to sexology and psychology. From 1978 until 2000 Forel's image appeared on the 1000 Swiss franc banknote. Early life Born in 1848 in a villa ''La Gracieuse'', at Morges, on Lake Geneva, Switzerland, to Victor Forel a pious Swiss Calvinist and Pauline Morin, a French Huguenot he was brought up in a protective household. Auguste Forel was born in 1848 at Morges on Lake Geneva in Switzerland. His great uncle, who was an entomologist, introduced Forel to insect natural history when he was young. After reading a book by Pierre Huber, he became interested in ants. Education He went to school at Morges and Lausanne. In 1866 he began his studies at the University o ...
