The eastern yellowjacket is a black and yellow wasp that lives in eastern North America. It builds paper nests, many of them underground, and lives in large family groups called colonies. People often meet it around recreational areas and buildings, and it can give a painful sting if its nest is threatened.1

Most nests are underground and not deep, usually covered by less than 50 mm of soil. Nests are also found in hardwood forests, on creek banks, in urban and suburban areas, and in sheltered places such as tree stumps and attics. Because nests are so often found in recreational and residential areas, it is considered a pest.1

Kaj je?

It is a polyphagous species, meaning it feeds on a variety of foods. Foraging workers can learn smells, which helps them find food.1

Kako jo prepoznaš

Black and yellow lines on the head, thorax and abdomen1
Length of about 12.7 to 15.9 mm1
Spots on the head, which give the species its scientific name1
Queens have one flared black line nearest the thorax, followed by thinner black lines, with two black dots between each line1

Pogosto zamenjujejo z: It can be told apart from other wasp species by its smaller size and its abdominal pattern. Other yellowjacket species are also black and yellow, and in most areas where it lives, this is the most common yellowjacket species.1

Its sting is painful. Wasps, bees, ants and sawflies (the order Hymenoptera) are the leading cause of anaphylaxis in humans, a severe allergic reaction. These reactions are usually triggered by proteins in the venom. Peptides called vespulakinins were first found in this species and are insecticidal, meaning they kill insects.1

It is known to inflict painful stings and defends its nest aggressively. Its nests are often treated as a pest because they are found so often in recreational and residential areas.1

Kaj naredi, ko se prestraši?

When threatened, workers release an alarm pheromone that calls others to attack. Wasps near the nest entrance circle in a zigzag pattern and fly straight at the target.1

Če piči

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.

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

A large nest can have 10,000 to 15,000 cells, and about a third of them are queen cells.1

The nest envelope is made from chewed, decaying wood mixed with saliva, which makes it fragile.1

The species is a host for a social parasite, Vespula squamosa, which can take over its nests.1

Males gather in groups around prominent trees and bushes, where they patrol and wait for queens.1

Queens can mate with several males, and both queens and males can mate more than once.1
