The western yellowjacket is a social wasp with a yellow and black body. It lives across the western half of North America and has spread to the Hawaiian Islands, where it is considered a major pest. Its colonies can grow very large in places without cold winters.1

It lives in open forest, prairies, urban areas, gardens, parkland, meadows and houses. Nests are usually built 10 to 15 cm below ground or in dark cavities such as rodent burrows or old logs.1

Kaj je?
Workers hunt insects and scavenge dead animals for meat, and feed on plant nectar for sugars. They chew prey into pieces, usually removing the head first from large insects, and in Hawaii they also raid honey bee colonies.1

Kako jo prepoznaš

  • Yellow and black pattern, typical of social wasps in the genus Vespula1
  • Most females have a continuous yellow ring around each eye, known as an eye-loop1
  • A diamond-shaped black mark on the first tergum (the upper plate of the abdomen)1
  • Nests are made of wood fibres and enclosed in a paper envelope, with an entrance tunnel of 10 to 30 cm at the bottom1

Pogosto zamenjujejo z: It is often misidentified as V. germanica, which has a similar diamond-shaped black mark. The continuous yellow eye-loop around each eye usually tells the western yellowjacket apart, though males often lack it.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: BolečeLahko zelo boli, a skoraj nikoli ni resno.

Če piči

  • Čebelje želo postrgaj ven in mesto ohladi.
  • Če ima poškodovanec težave z dihanjem, otekel obraz ali grlo ali se mu vrti, kot da bo omedlel, gre za nujno stanje zaradi alergije: pokliči številko za klic v sili in uporabi njegov adrenalinski avtoinjektor, če ga ima.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

  • Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
  • Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
  • Če te piči: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

1

Workers settle dominance within the nest by mauling, where one wasp chews on another that stays still.1

2

In Hawaii, the western yellowjacket has become so invasive that it is labelled a major pest.1

3

The nest is kept cleaner than those of many other social wasps, with waste, prey remains and dead larvae removed.1

4

Only the inseminated queen survives the winter, entering diapause (a resting state) until spring.1

5

Most foraging happens close to the nest, usually within about 335 metres, though some trips reach about 550 metres.1

6

Cold weather limits the number of western yellowjackets, but in places without cold winters their population can grow very quickly.1
