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

Anaishi

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

Asia

Nyumbani

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

Urefu

2 cm hadi 3 cm (0.8 in hadi 1.2 in)1

Kasi ya juu

takriban km 30 kwa saa (maili 19 kwa saa)

Hula nini?

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

Jinsi ya kumtambua

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

Mara nyingi huchanganywa na: 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

Kudungwa

Sumu hutoka kupitia mdungo.

Sumu yake hufanya nini?

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

Ana hatari gani kwa watu?

Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.

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

Hufanya nini akiogopa?

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

Akidunga

Kwangua mwiba wa nyuki na upoze mahali hapo.
Mtu akipata shida ya kupumua, uso au koo likivimba, au akijisikia kuzimia, hiyo ni dharura ya mzio: piga namba ya dharura na umtumie kalamu yake ya adrenalini kama anayo.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

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

Kuvunja dhana potofu

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

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