Hornet
Hornets (insects in the genus ''Vespa'') are the largest of the Eusociality, 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 Vespinae, vespine wasps by the relatively large vertex (anatomy), 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. ...

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] |
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 ...

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.

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 ...

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 sting their prey. The most commonly known wasps, such as yellowjackets and hornets, are in the family Vespidae and are 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 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. Females typically have an oviposit ...

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 ...

Australian Hornet
The Australian "hornet" (''Abispa ephippium''), a type of potter wasp or "mason wasp", is a vespid native to the Australian states and territories of the Australian Capital Territory, New South Wales, Northern Territory, Victoria, Queensland and Western Australia. Despite its namesake, it is not a true hornet. The Australian hornet is a solitary insect, forming small nests against buildings and other structures. The adult wasp feeds on flower nectar, while the larvae are fed caterpillars captured by the female. Description ''A. ephippium'' is in length. The insect is mostly orange, with a large central black patch on the top of the thorax, and a wide black band marking the abdomen. The insect's wings are largely translucent, but tinted orange with black areas at the wing's end. Life cycle Being a member of the potter wasp subfamily In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inc ...

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 ...

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, and a f ...
