The Asian giant hornet (Vespa mandarinia), also known as the northern 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 briefly found in the Pacific Northwest of North America from late 2019 but was eradicated by December 2024. Asian giant hornets prefer to live in low mountains and forests, while almost completely avoiding plains and high-altitude climates. They create nests by digging, co-opting pre-existing tunnels dug by rodents, or occupying spaces near rotten pine roots. The Asian giant hornet feeds primarily on larger insects, colonies of other eusocial ins…

Vespa soror, also known as the southern giant hornet, is a species of hornet present in India, Northern Thailand, Laos, Northern Vietnam, and parts of South China, including Hong Kong, Guangdong, Fujian, and Hainan Island. V. soror is one of the largest hornets, though smaller than the Asian giant hornet (V. mandarinia). The body lengths of the workers range from 26–35 mm, and those of queens range from 39–46 mm. Their nests are typically subterranean and found in forested areas. They are aggressive predators and have been observed to attack the nests of honeybees, wasps, and smaller hornet species. They also prey on mantids, dragonflies, butterflies, grasshoppers, and small vertebrates suc…

Asian Giant Hornet Vespa mandarinia Smith (1852) (Insecta: Hymenoptera: Vespidae). 
 
 
 
 
 
 
 Vespa mandarinia Smith, commonly called the Asian giant hornet, is the largest hornet in the world. Its size and distinctive markings make it easily distinguishable from other Asian hornet species. Not only is the wasp occasionally life-threatening to humans, it can decimate a number of insect colonies, most notably wild and farmed honey bees. Vespa mandarinia is native to Japan and occurs in several countries in Asia. The first Vespa madarinia hornet detected in the United States was in Washington State in 2019. This 5-page fact sheet written by Caitlin Gill,…

Geographic potential of the world's largest hornet, <i>Vespa mandarinia</i> Smith (Hymenoptera: Vespidae), worldwide and particularly in North America.. The Asian giant hornet (AGH, Vespa mandarinia ) is the world's largest hornet, occurring naturally in the Indomalayan region, where it is a voracious predator of pollinating insects including honey bees. In September 2019, a nest of Asian giant hornets was detected outside of Vancouver, British Columbia; multiple individuals were detected in British Columbia and Washington state in 2020; and another nest was found and eradicated in Washington state in November 2020, indicating that the AGH may have successfully wintered in North America. Be…

Phylogeographic Reconstruction to Trace the Source Population of Asian Giant Hornet Caught in Nanaimo in Canada and Blaine in the USA.. The Asian giant hornet, Vespa mandarinia , is an invasive species that could potentially destroy the local honeybee industry in North America. It has been observed to nest in the coastal regions of British Columbia in Canada and Washington State in the USA. What is the source population of the immigrant hornets? The identification of the source population can shed light not only on the route of immigration but also on the similarity between the native habitat and the potential new habitat in the Pacific Northwest. We analyzed mitochondrial COX1 sequences of…

Hornets are wasps of the genus Vespa in the subfamily Vespinae (the vespine wasps). They are the largest of the eusocial wasps. Species like the European hornet can grow to 35 mm (1.4 in) in length, while other species like the Asian giant hornet (Vespa mandarinia) can exceed 50 mm (2.0 in). They are similar in appearance to their close relatives, the yellowjackets, but are distinguished from other vespine wasps by the relatively large top margin of the head, or vertex. Worldwide, 22 species of Vespa are recognized. 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. Wa…

Risk assessment for the establishment of the Asian giant hornet ( <i>Vespa mandarinia</i> ) in the Pacific Northwest. Abstract The recent introduction of the Asian giant hornet ( Vespa mandarinia Smith) in the United States in late 2019 has raised concerns about its establishment in the Pacific Northwest and its potential deleterious effects on honey bees and their pollination services in the region. Therefore, we conducted a risk assessment of the establishment of V. mandarinia in Washington and Oregon on a county-by-county basis. Our tier-1 qualitative and semi-quantitative risk assessment relied on the biological requirements and ecological relationships of V. mandarinia in the environme…

Independent centromeric expansions define giant hornet genomes.. BACKGROUND: The Vespa lineage of hornets demonstrate the potential to displace native species and cause significant damage to US apiculture through predation. In spite of introductions in recent years to North America, eradication efforts have prevented the Northern Giant Hornet, Vespa mandarinia, from establishing. Improved genomic resources could offer insight into the traits that define this lineage: large body size variance, adaptability to new environments, and high potential for invasiveness. RESULTS: We sequenced and assembled genomes of two lineages of the northern giant hornet, Vespa mandarinia, and one of the Europea…

Insects, which are a type of arthropod, are the most numerous group of multicellular organisms on the planet, with over a million species identified so far. The title of heaviest insect in the world has many contenders, the most frequently crowned of which is the larval stage of the goliath beetle, Goliathus goliatus, the maximum size of which is at least 115 g (4.1 oz) and 11.5 cm (4.5 in). The highest confirmed weight of an adult insect is 71 g (2.5 oz) for a gravid female giant wētā, Deinacrida heteracantha, although it is likely that one of the elephant beetles, Megasoma elephas and Megasoma actaeon, or goliath beetles, both of which can commonly exceed 50 g (1.8 oz) and 10 cm (3.9 in),…

Early Alarm on the First Occurrence of the Southern Giant Hornet <i>Vespa soror</i> du Buysson, 1905 (Vespidae) in Europe.. An eco-monitoring program to assess the biodiversity of insects affected by yellow-legged hornet ( Vespa velutina ) trapping in the north of the Iberian Peninsula (Spain) revealed the first occurrence of the southern giant hornet Vespa soror (Hymenoptera, Vespidae) on the European continent. We present a detailed characterization, combining morphological characteristics and molecular tools for genetic identification, as well as key information on its identification with respect to other hornets found on the Iberian Peninsula. We discuss the most plausible pathways and…
