Quick answer
The Asian giant hornet is the largest hornet in the world, with queens reaching about 5 cm (2 in) long and a wingspan near 7.5 cm (3 in). Native to East and Southeast Asia, it is a powerful predator that hunts other insects, including honey bees, to feed its larvae. Its sting is painful and its venom potent, though it is not normally aggressive toward people unless its nest is disturbed.

Biology
Asian Giant Hornet (Vespa mandarinia) is classified as Insect with conservation status Least Concern. Typical weight about 0.001 kg; lifespan around Workers a few weeks; queens about a year.
Ecology
Diet: Carnivore (insects, especially other bees and wasps). Habitat: Forests and low mountains. Movement and social systems reflect those pressures.
People and this species
Learn before you travel or keep related pets. Wild individuals are not toys; captive care needs species-specific husbandry.

Size and appearance
The Asian giant hornet is a formidable insect, with queens growing to about 5 cm (2 in) long and large orange heads with prominent jaws. Its body is banded in orange and dark brown, and its wingspan can approach 7.5 cm (3 in). This size makes it the largest hornet species in the world.
Diet and hunting
These hornets are predators that hunt large insects, including other wasps, mantises, and especially honey bees, which they carry back to feed their larvae. A small group can raid a honey bee hive, decapitating thousands of bees to claim the nest and its brood. Adult hornets themselves feed largely on sugary fluids from prey and sap.
Sting and venom
The Asian giant hornet has a long stinger and potent venom that makes its sting very painful. While a single sting is rarely dangerous to a healthy adult, multiple stings can be serious, and people who are allergic are at higher risk. The hornet usually stings only when it or its nest is threatened.
Habitat and range
The Asian giant hornet is native to the forests and low mountains of East and Southeast Asia, including Japan, China, and Korea. It typically nests underground, often in abandoned rodent burrows or among tree roots. Sightings outside its native range have prompted monitoring because of its potential impact on local bees.
Research notes
Figures for asian giant hornets (Vespa mandarinia) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter asian giant hornets in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Least Concern) when discussing conservation.
