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

Inicio

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

Que come?

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

Como recoñecelo

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

Adoita confundirse con: 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

Poder da pezoña

A pezoña sae por un ferrete.

Que fai a súa pezoña?

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

Que perigoso é para as persoas?

Perigo para as persoas: DolorosoPode doer moito, pero case nunca é grave.

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

Que fai cando ten medo?

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

Se pica

Rasca para quitar o ferrete da abella e arrefría a zona.
Se a persoa ten dificultade para respirar, a cara ou a gorxa inchadas, ou sente que se vai desmaiar, é unha emerxencia alérxica: chama ao teu número de emerxencias e usa o seu autoinxector de adrenalina se ten un.

Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos

Mantente a salvo

Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
Se un te pica: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos

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

Desmontamitos

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

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