![]() Queens can exceed 50 mm (2 in), while workers are between 35 and 40 mm ( 1 + 2⁄ 5 and 1 + 3⁄ 5 in). The queens are considerably larger than workers. Its stinger is typically 6 mm ( 1⁄ 4 in) long and delivers a potent venom that, in cases of multiple hornets stinging simultaneously, can kill a human. ![]() ![]() The abdomen alternates between bands of dark brown or black, and a yellow-orange hue (consistent with its head color). The base of the fore legs is darker than the rest. Its fore legs are brighter than the mid and hind legs. The thorax is dark brown, with two grey wings varying in span from 35 to 76 mm ( 1 + 3⁄ 8 to 3 in). Its orange mandible contains a black tooth that it uses for digging. mandarinia is distinguished from other hornets by its pronounced clypeus and large genae. Its eyes and ocelli are dark brown to black. Regardless of sex, the hornet's head is a light shade of orange and its antennae are brown with a yellow-orange base. In July 2022, the Entomological Society of America stated that they will adopt the common name northern giant hornet for the species to avoid potentially discriminatory language, citing the rise in anti-Asian sentiment and hate crimes in the wake of the COVID-19 pandemic. Since its discovery in North America, the scientific literature and official government sources refer to this species by its established common name, Asian giant hornet, whilst the mainstream media have taken to using the nickname " murder hornet". The most recent revision in 2020 eliminated all of the subspecies rankings entirely, with "japonica", "magnifica", and "nobilis" now relegated to informal non-taxonomic names for different color forms. japonica has not been considered valid since 1997. Īs of 2012, three subspecies were recognized: V. ![]() The species has been around since the Miocene as indicated by fossils found in Shanwang formation. ĭivision of the genus into subgenera has been attempted in the past, but has been abandoned, due to the anatomical similarity among species and because behavioral similarity is not associated with phylogeny. The triangular shape of the apical margin of the clypeus of the female is diagnostic, the vertex of both species is enlarged, and the shape of the apex of the aedeagus is distinct and similar. The most closely related species within the species group is V. tropica species group, defined by the single notch located on the apical margin of the seventh gastral sternum of the male. mandarinia is a species in the genus Vespa, which comprises all true hornets. The hornet has a body length of 45 mm ( 1 + 3⁄ 4 in), a wingspan around 75 mm (3 in), and a stinger 6 mm ( 1⁄ 4 in) long, which injects a large amount of potent venom. It feeds primarily on larger insects, colonies of other eusocial insects, tree sap, and honey from honey bee colonies. mandarinia creates nests by digging, co-opting pre-existing tunnels dug by rodents, or occupying spaces near rotten pine roots. Īsian giant hornets prefer to live in low mountains and forests, while almost completely avoiding plains and high-altitude climates. However, by the end of the season in November 2022, there were no confirmed sightings in North America at all, suggesting they may have been eradicated in that region. 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. It is native to temperate and tropical East Asia, South Asia, Mainland Southeast Asia, and parts of the Russian Far East. The Asian giant hornet ( Vespa mandarinia) or northern giant hornet, including the color form referred to as the Japanese giant hornet, is the world's largest hornet. Vespa mandarina Dalla Torre, 1894 (misspelling).
