Hornets
Hornets (insects in the genus ''Vespa'') are the largest of the eusocial wasps, and are similar in appearance to yellowjackets, their close relatives. Some species can reach up to in length. They are distinguished from other vespine wasps by the relatively large top margin of the head. Worldwide, 22 species of ''Vespa'' are recognized.A.H. Smith-Pardo, J.M. Carpenter, L. Kimsey (2020) The diversity of hornets in the genus ''Vespa'' (Hymenoptera: Vespidae; Vespinae), their importance and interceptions in the United States. Insect Systematics and Diversity 4(3) https://doi.org/10.1093/isd/ixaa006 Most species only occur in the tropics of Asia, though the European hornet (''V. crabro'') is widely distributed throughout Europe, Russia, North America, and north-eastern Asia. Wasps native to North America in the genus '' Dolichovespula'' are commonly referred to as hornets (e.g., baldfaced hornets), but all of them are actually yellowjackets. Like other social wasps, hornets buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asian Giant Hornet
The Asian giant hornet (''Vespa mandarinia''), also known as the northern giant hornet, and the Japanese giant hornet, is the world's largest hornet. It is native to temperate and tropical East Asia, South Asia, mainland Southeast Asia, and parts of the Russian Far East. It was also found in the Pacific Northwest of North America in late 2019, with a few more additional sightings in 2020, and nests found in 2021, prompting concern that it could become an invasive species, but in December 2024, the hornets were announced to have been eradicated from the region, as well as from the rest of the United States.New York Times: Asian giant hornets prefer to live in low mountains and forests, while almost completely avoiding plains and high-altitude climates. ''V. mandarinia'' creates nests by digging, co-opting pre-existing tunnels dug by rodents, or occupying spaces near rotten pine roots. It feeds primarily on larger insects, colonies of other eusocial insects, tree sap, and honey fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Hornet
The European hornet (''Vespa crabro'') is the largest eusocial wasp native to Europe. It is also the only true hornet (genus ''Vespa'') found in North America, having been introduced to the United States and Canada from Europe as early as 1840. Vespines, such as ''V. crabro'', are known for making intricate paper-like nests out of surrounding plant materials and other fibers. Unlike most other vespines, reproductive suppression involves worker policing instead of queen pheromone control, as was previously thought. This species stings in response to being stepped on or grabbed, but generally avoids conflict. It is also defensive of its nest and can be aggressive around food sources. Care should be taken when they are found in these circumstances, as they may sting without warning. European hornets are largely carnivorous and hunt large insects such as beetles, wasps, large moths, dragonflies, and mantises. They also feed on fallen fruit and other sources of sugary food.

Oriental Hornet
The Oriental hornet (''Vespa orientalis'') is a social insect species of the family Vespidae. It can be found in Southwest Asia, Northeast Africa, the island of Madagascar (but no reports have been made of its presence on the island for many years), the Middle East, Central Asia, and parts of Southern Europe. Oriental hornets have also been found in a few isolated locations such as Mexico and Chile due to human introduction.Ríos, Mauro; Barrera, Roberto; Contreras, José (2020) Primer reporte del género ''Vespa'' Linnaeus (Hymenoptera: Vespidae: Vespinae) en Chile. ''Revista Chilena de Entomología'' 46:237-242. 10.35249/rche.46.2.20.14. The Oriental hornet lives in seasonal colonies consisting of caste system dominated by a queen. The hornet builds its nests underground and communicates using sound vibrations. The hornet has a yellow stripe on its cuticle (exoskeleton), which can absorb sunlight to generate a small electrical potential, and this might help supply energy for digg ...

Baldfaced Hornet
''Dolichovespula maculata'' is a species of wasp in the genus ''Dolichovespula'' and a member of the Eusociality, eusocial, cosmopolitan distribution, cosmopolitan family Vespidae. It is taxonomically an aerial yellowjacket but is known by many colloquial names, primarily bald-faced hornet, but also including bald-faced aerial yellowjacket, bald-faced wasp, bald hornet, white-faced hornet, blackjacket, white-tailed hornet, spruce wasp, and bull wasp. Technically a species of yellowjacket wasp, it is not one of the true hornets, which are in the genus ''hornet, Vespa''. Colonies contain 400 to 700 workers, the largest recorded colony size in its genus, ''Dolichovespula''. It builds a characteristic large hanging paper nest up to in length. Workers aggressively defend their nest by repeatedly stinging invaders. The bald-faced hornet is distributed throughout the United States and southern Canada, but is most common in the Southeastern United States. Males in this species are hapl ...

Provespa
''Provespa'' is a small genus of Vespidae, made up of nocturnal wasps from Southeast Asia, sometimes referred to as "night wasps" or "night hornets", though they are not true hornets (genus ''Vespa''). They are the only nocturnal members of the subfamily Vespinae, and also the only vespines where new colonies are formed by swarming (one queen attended by a large number of workers, similar to honey bees).Matsuura, M.

Yellowjacket
Yellowjacket or yellowjacket is the common name in North America for predatory social wasps of the genus, genera ''Vespula'' and ''Dolichovespula''. Members of these genera are known simply as "wasps" in other English-speaking countries. Most of these are black and yellow like the eastern yellowjacket (''Vespula maculifrons'') and the Dolichovespula arenaria, aerial yellowjacket (''Dolichovespula arenaria''); some are black and white like the Dolichovespula maculata, bald-faced hornet (''Dolichovespula maculata''). Some have an abdomen with a red background color instead of black. They can be identified by their distinctive markings, their occurrence only in colonies, and a characteristic, rapid, side-to-side flight pattern prior to landing. All females are capable of stinger, stinging. Yellowjackets are important predators of pest insects. Identification Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as ''Polistes dominula''. A typical y ...

Potter Wasp
Potter wasps (or mason wasps), the Eumeninae, are a Cosmopolitan distribution, cosmopolitan wasp group currently considered a subfamily of Vespidae, but sometimes recognized in the past as a separate family, Eumenidae. Mud dauber wasps, which also build their nests with mud, are in the families Sphecidae and Crabronidae and not discussed here. 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 Tropics, tropical regions, show faint to strong blue or green Metallic color, 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 Mesothorax#Mesoscutum, mesoscutum; # tarsal claws cleft; # hind Arthropod leg, coxae with a long ...

Vertex (anatomy)
In arthropod and vertebrate anatomy, the vertex (or ''cranial vertex'') is the highest point of the head. In humans, the vertex is formed by four bones of the skull: the frontal bone, the two parietal bones, and the occipital bone. These bones are connected by the coronal suture between the frontal and parietal bones, the sagittal suture between the two parietal bones, and the lambdoid suture between the parietal and occipital bones. ''Vertex baldness'' refers to a form of male pattern baldness in which the baldness is limited to the vertex, resembling a tonsure. In childbirth, ''vertex birth'' refers to the common head-first presentation of the baby, as opposed to the buttocks-first position of a breech birth. In entomology, the color and shape of an insect's vertex and the structures arising from it are commonly used in identifying species.

Khanty-Mansiysk
Khanty-Mansiysk (, lit. ''Khanty-Mansi Town''; Khanty: , ''Jomvoćś''; Mansi: , ''Abga'') is a city in west-central Russia. Technically, it is situated on the eastern bank of the Irtysh River, from its confluence with the Ob, in the oil-rich region of Western Siberia. Though it is an independent city, Khanty-Mansiysk also functions as the administrative centre of Khanty-Mansiysky District, and the administrative center of Khanty-Mansi Autonomous Okrug–Yugra. With 101,466 estimated inhabitants, Khanty-Mansiysk is among Russia's few regional capitals that are not the largest cities in their surrounding area, as it is surpassed in population by Surgut, Nizhnevartovsk and Nefteyugansk. Etymology Khanty-Mansiysk is a hyphenated word combining the names of two Russian indigenous peoples local to the region, the Khanty and the Mansi, ending in "-''sk''" as is typical for the names of Russian towns, which means city. Before 1940, the settlement's name was Ostyako-Vogulsk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
