Novomessor
''Novomessor'' is a genus of ants that was described by Italian entomologist Carlo Emery in 1915. Until recently, the genus was thought to be a synonym of ''Aphaenogaster'', but a 2015 phylogenetic study concluded that the two genera were distinct, reviving ''Novomessor'' from synonymy. Three species are currently described. This genus is known to inhabit the deserts of southwestern United States and Northern Mexico.

Novomessor Albisetosus
''Novomessor albisetosus'', also known as the desert harvester ant, is a species of ant found in the United States and Mexico. A member of the genus ''Novomessor'' in the subfamily Myrmicinae, it was first described by Austrian entomologist Gustav Mayr in 1886. It was originally placed in the genus ''Aphaenogaster'', but a recent phylogenetic study concluded that it is genetically distinct and should be separated. It is a medium-sized species, measuring and has a ferruginous body color. It can be distinguished from other ''Novomessor'' species by its shorter head and subparallel eyes. ''Novomessor albisetosus'' is found in desert and woodland habitats, nesting underground or under stones. The ants are active during the morning and evening but not when it is midday or the middle of the night. They forage for foods such as insect pieces, plant tissues and fruit. They may forage individually but cooperate when transporting large food items. Army ants are known to prey on this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Novomessor Ensifer
''Novomessor ensifer'' is a species of ant endemic to Mexico. A member of the genus ''Novomessor'' in the subfamily Myrmicinae, it was first described by Swiss entomologist Auguste Forel in 1899. ''N. ensifer'' was originally a part of the genus ''Aphaenogaster'' until a recent phylogenetic study concluded that ''Novomessor'' was genetically distinct and should be separated. The ant is a medium-sized species, measuring . The ant is ferruginous-colored in some certain parts of the body, and small workers (nanitics) in incipient colonies are noticeably different in color and body structure. ''N. ensifer'' is active throughout the day, where they forage on the ground and sometimes on low herbs. Colonies are found under stones and other objects in tropical dry forests and pine-oak forests. These ants are solitary foragers and predominantly feed on insects such as wasps and moths. The only known predator of ''N. ensifer'' is the giant horned lizard (''Phrynosoma asio''). While noth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Novomessor Cockerelli
''Novomessor cockerelli'' is a species of ant in the subfamily Myrmicinae. It is native to the deserts of the Southwestern United States and Mexico. It lives in large underground colonies in which there is a single queen. The worker ants leave the nest daily to forage for seeds, plant material and dead insects. Description ''Novomessor cockerelli'' is a large brown ant with a blackish gaster, long legs and an elongated head. It can be recognised by the two distinctive spines on the propodeum. It can be distinguished from the rather similar '' Novomessor albisetosus'' by the shape of its head. It cannot sting but is very aggressive and has a powerful bite. Distribution and habitat ''Novomessor cockerelli'' is found in arid areas of the Southwestern United States including Texas and the Franklin Mountains, New Mexico, Arizona, Nevada and California. It is also present in northern Mexico in the states of Sonora, Chihuahua, Durango, Coahuila and Nuevo León. Its typical hab ...

Myrmicinae
Myrmicinae is a subfamily of ants, with about 140 extant genera; their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees.Goulet, H & Huber, JT (eds.) (1993) Hymenoptera of the world: an identification guide to families. Agriculture Canada. p. 224 Identification Myrmicine worker ants have a distinct postpetiole, i.e., abdominal segment III is notably smaller than segment IV and set off from it by a well-developed constriction; the pronotum is inflexibly fused to the rest of the mesosoma, such that the promesonotal suture is weakly impressed or absent, and a functional sting is usually present. The clypeus is well-developed; as a result, the antennal sockets are well separated from the anterior margin of the head. Most myrmicine genera possess well-developed eyes and frontal lobes that partly conceal the an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carlo Emery
Carlo Emery (25 October 1848, Naples – 11 May 1925) was an Italian entomologist. He is remembered for Emery's rule, which states that insect social parasitism (biology), social parasites are often closely related to their hosts. Early in his career Carlo Emery pursued a course in general medicine, and in 1872 narrowed his interests to ophthalmology. In 1878 he was appointed Professor of Zoology at the University of Cagliari, remaining there for several years until 1881 when he took up an appointment at the University of Bologna as Professor of Zoology, remaining there for thirty-five years until his death. Emery specialised in Hymenoptera, but his early work was on Coleoptera. Prior to 1869, his earliest works were a textbook of general zoology and papers on fishes and molluscs. From 1869 to 1925 he devoted himself almost entirely to the study of ants. Emery published extensively between 1869 and 1926 describing 130 genera and 1057 species mainly in Philogène Auguste Gali ...

Aphaenogaster
''Aphaenogaster'' is a genus of myrmicine ants. About 200 species have been described, including 18 fossil species. They occur worldwide except in South America south of Colombia, sub-Saharan Africa, and Antarctica. They are often confused with ''Pheidole'' or ''Pheidologeton''. These two have major and minor workers, while ''Aphaenogaster'' has only a single worker caste. ''Pheidole'' has three-segmented clubs on its antennae, while ''Aphaenogaster'' has four segments and a larger body size. ''Pheidologeton'' has 11-segmented antennae, while the antennae in ''Aphaenogaster'' are 12-segmented.Genus ''Aphaenogaster'' In Australia, they often build dense, conspicuous nests.Richards, P.J.

Ant Genera
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists. Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens" (gynes). The colonies are described as superorganisms because the ants a ...

Hymenoptera Of North America
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Of The United States
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 eg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
