The 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

Com reconèixer-lo

  • 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

Sovint es confon amb: 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

Poder del verí

Picades

El verí surt per un fibló.

Què fa el seu verí?

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

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

Què fa quan té por?

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

Si pica

  • 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
  • Rasca el fibló de l'abella per treure'l i refreda la zona.
  • Si a la persona li costa respirar, se li infla la cara o la gola, o sent que es mareja, és una emergència al·lèrgica: truca al número d'emergències i fes servir el seu autoinjector d'adrenalina si en té.

Truca sempre primer al número d'emergències (112, 000, 911). Això són pautes generals de primers auxilis, no consells mèdics. Primers auxilis bàsics

Estigues segur

  • No toquis, atrapis ni molestis mai un animal salvatge, encara que sigui petit i encara que sembli adormit o mort.
  • Deixa-li espai. Si en trobes un, mantén la calma, recula a poc a poc i deixa que segueixi el seu camí.
  • Si te'n pica un: mantén la calma, no et moguis, truca al número d'emergències (112, 000, 911) o ves de pressa a un hospital. Recorda com era, una foto ajuda.

No va a per tu. Fa servir el verí per caçar o per defensar-se, i prefereix mil vegades amagar-se. Més sobre com estar segur
