The Asian hornet is a hornet from Southeast Asia that has spread to many other countries, including most of Europe, where it is an invasive species. It is a concern because it hunts honeybees and its stings can be serious for people.1

Leef in

Native to Southeast Asia. Invasive in much of Europe, Japan, South Korea, parts of the United States, New Zealand and Algeria.1

Asië

Tuis

Hornets build paper nests, which can hold several thousand individuals. Nests start in a low shrub and are often moved high into a tree after some months. Hornets hunt over beehives and apiaries, where people keeping bees can meet them, and people may be attacked when they disturb a nest.1

Lengte

2 cm tot 3 cm (0,8 in tot 1,2 in)1

Topspoed

omtrent 30 km/h (19 mph)

Vlieënd, rowwe skatting

Wat eet dit?

It hunts a wide range of insects, including flies, dragonflies and grasshopper-type insects (Orthoptera), usually by chasing them in flight. Where it finds honeybee colonies, it tends to specialise in catching honeybees.1

Hoe om dit te herken

Queens are about 3 cm long, males about 2.4 cm and workers about 2 cm, so it is significantly smaller than the European hornet.1
Its legs (tarsi) are yellow, which gives it the name yellow-legged hornet.1
The thorax is velvety brown or black, with a brown abdomen.1
Each abdominal segment has a narrow yellow border at the back, except the fourth segment, which is orange.1
The head is black and the face is yellow.1

Word dikwels verwar met: It looks like the European hornet (V. crabro), which is much larger. Its nest exit is usually on the side rather than at the bottom.1

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

Multiple stings have caused anaphylactic shock, a severe allergic reaction, in people who were hospitalised in France.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

Although the species is not aggressive, people have been attacked after disturbing nests. A man in Galicia, Spain, was killed in 2017 after being stung over 20 times while pruning an apple tree. Several people have died in south west France, including in 2019 and 2020. Because of its larger size, its stings are more serious than those of western honeybees.1

Wat doen dit as dit bang is?

When it feels its nest is threatened, it charges in a group.1

As dit steek

Skraap 'n byangel uit en koel die plek af.
As die persoon sukkel om asem te haal, die gesig of keel swel, of hy voel flou, is dit 'n allergiese noodgeval: bel jou noodnommer en gebruik sy adrenalienpen (outo-inspuiter) as hy een het.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Hoe groot is dit?

Hoe lank is dit?

Feite

In its native range, its main prey is the eastern honeybee, which defends the hive by balling hornets and raising the temperature inside the ball to a level that kills the hornet.1

A hornet hunting honeybees holds a territory of about 0.5 m² above a beehive and catches bees as they return to the hive.1

It is believed to have reached France in boxes of pottery from China in 2004.1

A colony often starts a nest in a low shrub, then abandons it after some months and builds a new one high in a tree, possibly to avoid parasites.1

Young queens leave the colony in late autumn and hibernate over winter.1

Mite-breker

Mite: Asian hornets are aggressive and will attack anyone who comes near.

Waarheid: The species is not aggressive, but it will charge in a group when it feels its nest is threatened.1
