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

Leef in

Eastern North America, extending west as far as the Great Plains1

Noord-Amerika

Tuis

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

Wat eet dit?

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

Hoe om dit te herken

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

Word dikwels verwar met: 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

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

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

Wat doen dit as dit bang is?

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

As dit steek

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

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
