European hornet
StekeThe European hornet is the largest wasp that lives in Europe. It is a true hornet, and it is the only one of its kind found in North America, where it was introduced from Europe. It is best known for its large paper nests and its striking reddish wings and striped abdomen.1
Hoe om dit te herken
- Eyes deeply indented and shaped like a "C"1
- Reddish-orange wings1
- Abdomen striped with brown and yellow1
- Workers average about 2.5 cm long; queens can reach about 3.5 cm1
- Has hair on the thorax and abdomen, but is not as hairy as most bees1
Word dikwels verwar met: It is often mistaken for the Asian giant hornet because of its colours and abdomen pattern. The European hornet is significantly smaller than the Asian giant hornet, and it is larger than most common wasps, such as Vespula vulgaris.1
Gifkrag
Gif kom deur 'n angel uit.
Wat doen sy gif as dit byt of steek?
Its venom contains neurotransmitters such as dopamine, serotonin, histamine and noradrenaline, along with enzymes, proteins such as melittin and bradykinin, and a neurotoxin called apamin, which attacks the nerves. In one documented case, a person developed tingling at the sting, headaches and shortness of breath, along with a fast, irregular heartbeat.1
Hoe gevaarlik is dit vir mense?
Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.Most stings do not need medical attention, but in rare cases they can be serious. In one documented case the victim needed hospital treatment, though that person may have been unusually sensitive to hornet and wasp stings.1
Wat doen dit as dit bang is?
It stings when it is stepped on or grabbed and is defensive of its nest, and it may sting without warning when near its nest or food. When alarmed, it performs a dance outside the nest with loud buzzing, darting in and out, and attacking or approaching the target.1
As dit steek
- Most stings do not require medical attention. In rare serious cases, hospital treatment is needed; in one documented case, electrical cardioversion or the drug propafenone were effective treatments for the heart reactions.1
- 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

Feite
It is known to steal prey from spiders. This was first documented in 2011, when one took a wrapped insect from a yellow garden spider's web.1
It is the largest eusocial wasp native to Europe.1
Only females have a stinger, because it is a modified egg-laying device. Males cannot sting.1
In Germany, killing a European hornet or destroying its nest has been illegal since 1 January 1987, with a fine of up to €50,000, though fines are rarely imposed.1
It is the only true hornet found in North America, where it was introduced from Europe as early as 1840.1
Mite-breker
Mite: European hornets are aggressive and will attack people for no reason.
Waarheid: It generally avoids conflict. It stings mainly when it is stepped on or grabbed, or when its nest or food is threatened.1
