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.

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.

Vespa (genus)
Hornets (insects in the genus ''Vespa'') are the largest of the eusocial wasps, and are similar in appearance to their close relatives yellowjackets. 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.

Palaeovespa
''Palaeovespa'' is an extinct genus of wasp in the Vespidae subfamily Vespinae. The genus currently contains eight species, five from the Priabonian stage Florissant Formation in Colorado, United States two from the middle Eocene Baltic amber deposits of Europe. and one species from the late Paleocene of France. History and classification The genus was first described by Dr. Theodore Cockerell in a 1906 paper published in the ''Bulletin of the Museum of Comparative Zoology''. The genus name is a combination of the Greek ', meaning "old" and ''vespa'' from the genus ''Vespa'', the type genus of the family Vespidae where ''Palaeovespa'' is placed. Along with the genus description, the paper contained the description of the type species ''P. florissantia'', ''P. scudderi'' and ''P. gillettei'' all from the Florissant Formation. Cockerell described a fourth species, ''P. baltica'' in 1909 from a specimen in Baltic amber. Five years later, in 1914, Cockerell described another specie ...

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. (1999) Size and composition of swarming colonies in ''Provespa anomala'' (Hymenoptera, Vespidae), a nocturnal social wasp. Insectes Sociaux Volume 46,pp 219-223. They tend to build their nests from fibrous plant material, making them a uniform greyish brown colour which is often difficult to locate.

Vespidae
The Vespidae are a large (nearly 5000 species), diverse, cosmopolitan family of wasps, including nearly all the known eusocial wasps (such as ''Polistes fuscatus'', ''Vespa orientalis'', and ''Vespula germanica'') and many solitary wasps. Each social wasp colony includes a queen and a number of female workers with varying degrees of sterility relative to the queen. In temperate social species, colonies usually last only one year, dying at the onset of winter. New queens and males (drones) are produced towards the end of the summer, and after mating, the queens hibernate over winter in cracks or other sheltered locations. The nests of most species are constructed out of mud, but polistines and vespines use plant fibers, chewed to form a sort of paper (also true of some stenogastrines). Many species are pollen vectors contributing to the pollination of several plants, being potential or even effective pollinators, while others are notable predators of pest insect species.

Dolichovespula
''Dolichovespula'' is a small genus of social wasps distributed widely throughout the Northern Hemisphere. The yellow and black members of the genus are known by the common name yellowjackets in North America, such as ''Dolichovespula norwegica'', along with members of their sister genus ''Vespula''. In a study on the nesting biology of ''Dolichovespula'', a colony of '' D. maculata'' with 771 workers was reported as having the largest recorded population count. Overview Several morphological differences distinguish them from ''Vespula''. The most noticeable is the long face (''dolikhos'' = "long" in Greek). Viewed from the front, ''Dolichovespula'' faces are long, while ''Vespula'' faces are short and round. The oculomalar space, the distance between the eye and the mandible, is long in ''Dolichovespula'' and short in ''Vespula''. ''Dolichovespula'' nests are usually aerial, while ''Vespula'' spp. often nest underground. Reproduction All females are born with reproductive cap ...

Eusociality
Eusociality (from Greek εὖ ''eu'' "good" and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes referred to as 'castes'. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms. Eusociality exists in certain insects, crustaceans, and mammals. It is mostly observed and studied in the Hymenoptera (ants, bees, and wasps) and in Blattodea (termites). A colony has caste differences: queens and reproductive males take the roles of the ...

Wasp
A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder. The wasps do not constitute a clade, a complete natural group with a single ancestor, as bees and ants are deeply nested within the wasps, having evolved from wasp ancestors. Wasps that are members of the clade Aculeata can Stinger, sting their prey. The most commonly known wasps, such as yellowjackets and hornets, are in the family Vespidae and are Eusociality, eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex-determination system, sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each other. However, the majority of wasp species are solitary, with each adult female living and breeding independently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vespula
''Vespula'' is a small genus of social wasps, widely distributed in the Northern Hemisphere. Along with members of their sister genus ''Dolichovespula'', they are collectively known by the common name yellowjackets (or yellow jackets) in North America. ''Vespula'' species have a shorter oculomalar space (shown in the figure below right) and a more pronounced tendency to nest underground than ''Dolichovespula''. Notable species * While most species of this genus inhabit North America, four ''Vespula'' species inhabit Europe, namely ''V. austriaca, V. germanica, V. rufa'' and ''V. vulgaris'' * Two common European species, the German wasp (''Vespula germanica'') and the common wasp (''Vespula vulgaris''), have established in other countries: both species are now found in New Zealand, Australia and South America, while the former has also been introduced in North America, and the latter in southern Africa. * The eastern yellowjacket (''Vespula maculifrons'') and western yellowjacket ...
