Hover Wasp
The Stenogastrinae are a subfamily of social wasps included in the family Vespidae. They are sometimes called hover wasps owing to the particular hovering flight of some species. Their morphology and biology present interesting peculiarities. Systematic position The first reports on stenogastrine wasps can be found in a book of Guérin de Méneville (1831) with the first known species, ''Stenogaster fulgipennis''. Henri Louis Frédéric de Saussure treated their systematic position and remarked that these wasps were, in all their characters, entirely intermediate between the two subfamilies of Eumeninae and Vespinae. In 1927, Anton von Schulthess-Rechberg created the new genus ''Parischnogaster'' for some species living in the Oriental region. Dutch entomologist Jacobus van der Vecht created four new genera including species from the entire area of distribution and described tens of new species. He revised the two Papuan genera'' Anischnogaster'' and ''Stenogaster '' and the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parischnogaster Mellyi
''Parischnogaster mellyi'' is a medium-sized species of a hover wasp in the family Vespidae. It is found in Southeast Asia and is widely spread in Thailand and Malaysia. Its nests feature flexible and dynamic qualities, and they are commonly seen under roofs of houses and huts in rural areas. Hovering and patrolling behaviors are the species’ main defining behavioral features, and such activities are closely linked to its mating patterns. Taxonomy and phylogeny All hover wasp species were placed under one genus, ''Stenogaster'', until 1927, when von Schulthess created the new genus, Parischnogaster, for species populated in Asia. ''Parischnogaster'' was synonymized with Holischnogaster by Carpenter in 1982, and it is possibly the largest and the least well known genus. ''P. mellyi'' was first found by De Saussure in 1852. Understanding of phylogenetic background for ''P. mellyi'' is of particular importance because “the independence of origin and range of social organizatio ...

Parischnogaster (jacobsoni Group)
''Parischnogaster'' is a genus of hover wasps from the subfamily Stenogastrinae, a subfamily of eusocial wasps endemic to the Oriental Region which are included in the family Vespidae. Species The following species are some of those included within the genus ''Parischnogaster'': *'' Parischnogaster albofasciata'' Selis, 2018 *''Parischnogaster alternata'' Sakag., 1969 *'' Parischnogaster aurifrons'' (Smith, 1862) *'' Parischnogaster carepenteri'' Selis, 2018 *'' Parischnogaster curvylypeus'' Selis, 2018 *'' Parischnogaster depressigaster'' Rohwer, 1919 *'' Parischnogaster giglii'' Selis, 2015 *'' Parischnogaster gracilipes'' (Vecht, 1977) *'' Parischnogaster jacobsoni'' ( R. du Buysson, 1913) *''Parischnogaster mellyi'' (de Saussure, 1852) *'' Parischnogaster mindanaobis'' Selis, 2018 *'' Parischnogaster nigerrima'' Selis, 2018 *'' Parischnogaster nigricans'' ( Cameron, 1902) **''Parischnogaster nigricans serrei'' ( R. du Buysson, 1905) *'' Parischnogaster nigriterga'' Selis, 20 ...

Parischnogaster Striatula
''Parischnogaster striatula'' is a species of social hover wasps found in Southeast Asia. Their nests are uniquely shaped, mimic their surroundings and, like the other Stenogastrinae social wasps, lack a nest pedicel. They are also unique in their use of glandular secretion when laying eggs. ''P. striatula'' is also different than typical wasps because the queens are not the only ones who possess reproductive capabilities; other females also have developed ovaries. This wasp is also known for fiercely protecting its nest against enemies, such as ants or other hornets. Taxonomy and phylogeny ''P. striatula'' is under the subfamily Stenogastrinae, sometimes known as hover wasps. While the Stenogastrinae taxonomy and phylogeny are still under study, it is known that ''Parischnogaster'' species are split into two subcategories, with ''P. striatula'' being closely related to '' P. alternata''. Together, these two species make up the striatula group. Description and identification ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liostenogaster Vechti
''Liostenogaster vechti'' is a type of eusocial hover wasp within the family Vespidae. They are typically brown and yellow in color and are considered a passive aggressive species. Their stings are less painful to humans than other social wasps, and they engage in associative nest foundation. They are mostly found on the Malaysian peninsula and are known for living in large clusters of small ring-shaped nests. Taxonomy and phylogeny ''Liostenogaster vechti ''was first classified by Stefano Turillazzi in 1988. These wasps are part of the subfamily Stenogastrinae and are often referred to as hover wasps due to their manner of flying. Stenogastrinae has many other groups that are distributed across the Oriental region, but the species most closely associated with ''L. vechti'' is '' L. flavolineata'' due to similar coloring, behavioral patterns, and the similar locations of the two species. Description and identification The adult females are 14 to 16 mm in length with d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propodeum
The propodeum or propodium is the first abdominal segment in Apocrita Hymenoptera (wasps, bees and ants). It is fused with the thorax to form the mesosoma. It is a single large sclerite, not subdivided, and bears a pair of spiracles. It is strongly constricted posteriorly to form the articulation of the petiole, and gives apocritans their distinctive shape. There may be a suture between the propodeum and the thorax, like in Symphyta Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay ... or not, and the presence or absence of such suture can aid in identifying specimens. In molluscs Propodium is the anterior (frontal) part of the foot of a mollusk. References Insect anatomy Gastropod anatomy {{insect-anatomy-stub ...

Eumeninae
Potter wasps (or mason wasps), the Eumeninae, are a cosmopolitan wasp group presently treated as a subfamily of Vespidae, but sometimes recognized in the past as a separate family, Eumenidae. Recognition Most eumenine species are black or brown, and commonly marked with strikingly contrasting patterns of yellow, white, orange, or red (or combinations thereof), but some species, mostly from tropical regions, show faint to strong blue or green metallic highlights in the background colors. Like most vespids, their wings are folded longitudinally at rest. They are particularly recognized by the following combination of characteristics: # a posterolateral projection known as a parategula on both sides of the mesoscutum; # tarsal claws cleft; # hind coxae with a longitudinal dorsal carina or folding, often developed into a lobe or tooth, and; # fore wings with three submarginal cells. Biology Eumenine wasps are diverse in nest building. The different species may either use existi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masarinae
Pollen wasps, the Masarinae, are unusual wasps that are typically treated as a subfamily of Vespidae, but have in the past sometimes been recognized as a separate family, "Masaridae", which also included the subfamilies Euparagiinae and Gayellinae. It is a small subfamily, unique among wasps in feeding their larvae exclusively with pollen and nectar, in a fashion quite similar to many solitary bees. Most species are black or brown, marked with strikingly contrasting patterns of yellow, white, or red (or combinations thereof). They are most diverse and abundant in the desert regions of southern Africa, but also occur in the deserts of North and South America. Some species of '' Pseudomasaris'' in California, such as '' Pseudomasaris vespoides'', bear a remarkable resemblance to yellow jackets, but can be recognized by their strongly clubbed antennae, a characteristic feature of the subfamily. Males have greatly elongated antennae, but still ending in a strong club. They carry poll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vespinae
The subfamily Vespinae contains the largest and best-known eusocial wasps, including true hornets (the genus ''Vespa''), and the "yellowjackets" (genera ''Dolichovespula'' and ''Vespula''). The remaining genus, ''Provespa'', is a small, poorly known group of nocturnal wasps from Southeast Asia. One genus, ''Palaeovespa'', has been described from the Eocene fossil record, from Colorado. Collectively, the group can be found on all continents except Antarctica, and several of these wasps are invasive species An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species ad ..., introduced beyond their native ranges, and can be major pests.

Polistinae
The Polistinae is a subfamily of eusocial wasps belonging to the Family (biology), family Vespidae. They are closely related to the more familiar wasps (“yellowjackets” as they are called in North America) and true hornets of the subfamily Vespinae, containing four tribes. With about 1,100 species total, it is the second-most diverse subfamily within the Vespidae, and while most species are tropical or subtropical, they include some of the most frequently encountered large wasps in temperate regions. The Polistinae are also known as paper wasps, which is a misleading term, since other wasps (including the wasps in the subfamily Vespinae) also build nests out of paper, and because some epiponine wasps (e.g., ''Polybia emaciata'') build theirs out of mud, nonetheless, the name "paper wasp" seems to apply mostly, but not exclusively, to the Polistinae, especially the Polistini. Many polistines, such as ''Polistes fuscatus,'' ''Polistes annularis'', and ''Polistes exclamans'', m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henri Louis Frédéric De Saussure
Henri Louis Frédéric de Saussure (; ; 27 November 1829 – 20 February 1905) was a Swiss mineralogist and entomologist specialising in studies of Hymenoptera and Orthopteroid insects. He also was a prolific taxonomist. Biography Saussure's elementary education was at Alphonse Briquet's then, as an adolescent, at the Hofwyl school run by Philipp Emanuel von Fellenberg. At the University of Geneva he was taught by François Jules Pictet de la Rive, who introduced him to entomology. After several years of study in Paris he received the degree of licentiate of the Faculty of Paris and obtained the degree of Doctor from the University of Giessen. He worked mainly on Hymenoptera and Orthoptera. His first paper, in 1852, was on solitary wasps. In 1854 he traveled to the West Indies, then to Mexico and the United States of America. There he met Louis Agassiz. He returned to Switzerland in 1856 with collections of American insects, myriapods, crustaceans, birds and ...
