In brief
The Asian giant hornet (Vespa mandarinia) is the world's largest hornet, with queens reaching up to 5 cm long and a wingspan close to 7.5 cm. Native to the forests and low mountains of East and Southeast Asia, it is a powerful predator that hunts other insects and can fly at up to 40 km/h.

The Asian giant hornet (Vespa mandarinia) is the world's largest hornet, with queens reaching up to 5 cm long and a wingspan close to 7.5 cm. Native to the forests and low mountains of East and Southeast Asia, it is a powerful predator that hunts other insects and can fly at up to 40 km/h. Colonies last a single year, and despite its fearsome reputation the species is common and listed as Least Concern.

Key Facts: Asian Giant Hornet
- The Asian giant hornet earns its name: queens can reach about 5 cm in length, with workers a little smaller at around 3.5 to 4.5 cm, and a wingspan approaching 7.5 cm.
- Asian giant hornets are carnivores that prey on other insects, particularly bees and wasps.
- Like other social wasps, the Asian giant hornet lives in an annual colony that lasts a single year.
The world's largest hornet
The Asian giant hornet earns its name: queens can reach about 5 cm in length, with workers a little smaller at around 3.5 to 4.5 cm, and a wingspan approaching 7.5 cm. Its large orange-yellow head, dark thorax and boldly banded abdomen make it unmistakable. Powerful wings let it fly at speeds of up to 40 km/h and cover long distances in a day. This impressive size and strength make it a formidable hunter of other insects.
Hunting and diet
Asian giant hornets are carnivores that prey on other insects, particularly bees and wasps. Adults hunt widely, using their large jaws to dismember prey, and carry protein-rich meat back to feed the colony's developing larvae. They are best known for raiding honeybee hives, where a small group of hornets can slaughter thousands of bees to seize the brood inside. In turn the adult hornets feed largely on sugary secretions produced by their own larvae.
Colony life and life cycle
Like other social wasps, the Asian giant hornet lives in an annual colony that lasts a single year. A mated queen emerges in spring to found a nest, usually in a burrow or hollow at ground level, and raises the first workers herself. Through summer the colony grows as sterile female workers, which live only a few weeks each, expand the nest and gather food. In autumn the colony produces new queens and males; the old colony then dies, and only young mated queens survive the winter to start again.
The sting and danger to people
The Asian giant hornet has a sting several millimetres long that can pierce ordinary clothing, delivering a potent venom. A single sting is very painful, and multiple stings can be dangerous, especially to people who are allergic. In parts of its range it is responsible for a number of deaths each year, usually where victims disturb a nest and are stung many times. That said, the hornet is not aggressive away from its nest and generally ignores people who leave it alone.
Range and habitat
The species is native to eastern and southern Asia, from Japan and the Korean Peninsula through China to parts of Southeast Asia. It favours forests and low mountains, where it can find both prey and suitable ground sites for nesting. Nests are typically hidden underground in abandoned rodent burrows or among tree roots. The hornet is widespread across this range and is classed as Least Concern by the IUCN.
The "murder hornet" reputation
The Asian giant hornet drew worldwide attention when a few individuals turned up in North America, earning it the sensational nickname 'murder hornet'. The alarm centres on its ability to devastate honeybee colonies, which threatens both wild pollinators and beekeeping. Interestingly, some Asian honeybees have evolved a defence, swarming over an intruding hornet and cooking it to death with their combined body heat. Efforts to detect and remove any nests outside its native range aim to protect local bees.
What WARN Does
WARN does not run a dedicated asian giant hornet programme — this guide is part of the World Animal Rescue Network's free educational library. The asian giant hornet is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that. Building public understanding of species like the asian giant hornet supports the broader conservation awareness that underpins WARN's partner-led rescue work across its network.
If clear, science-based wildlife guides like this help you understand and value animals, please consider supporting the World Animal Rescue Network's educational and rescue work so we can keep producing them.
